Abstract

The crude methanol, acetone and water extracts of leaves and pits of three varieties ofPhoenix dactylifera were tested for antibacterial action against selected Gram positive and Gram negative pathogenic bacteria. Barring Enterococcus faecalis, the acetone and methanol extracts showed good antibacterial activity against Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa, Shigella flexeneri, Staphylococcus aureus, and Streptococcus pyogenes, whereas the water extract had very little effect on all test bacterial species and there was almost negligible effect on P. aeruginosa. Pits extracts of all three varieties of P. dactylifera were found to be more effective than leaves extracts. Results clearly showed that S.pyogenes was most sensitive pathogen to the crude extracts and had shown maximum zone of inhibition. Minimum inhibitory concentration (MIC) for S. pyogenes was found to be 1.3, 1.1, 1.6 and 1.4 mg/ml for methanol leaves and pits extracts and acetone leaves and pits extracts, respectively. Key words: Date palm, Phoenix dactylifera L, antibacterial, crude extracts.

Antibiotic-resistant microorganisms have been an ever-growing concern over the past years. This has led researchers to direct their attention onto plants to be able to discover new possible antimicrobial compounds. The Middle East encompasses a wide spectrum of plant diversity with over 20,000 different species in habitats ranging from deserts to snow-capped mountains. Several plant secondary metabolites and their derivatives have been identified as possible antimicrobial agents. Among the secondary metabolites studied, alkaloids and polyphenols have shown strong antimicrobial activity. Polyphenols are one of the most numerous and diverse group of secondary metabolites; their antioxidant properties provide the basis for antimicrobial effects. Alkaloids provided the underlying structure for the development of several antibiotics with a diverse range of action. The ability of some plant secondary metabolites to act as resistance-modifying agents is a promising field in mitigating the spread of bacterial resistance.

A new ingredient from date palm coproducts (pits) was obtained and tested as a preservative in burgers. Different concentrations of date pit (0%, 1.5%, 3%, and 6%) were added to beef burgers, and its effect on the safety and quality was evaluated during 10 days of storage. The incorporation of date pit was able to improve the shelf life and the cooking properties of the burgers. The date pit stabilized the color, lipid oxidation, and microbial growth of the burgers during the storage time due to the antioxidant activity and the phytochemical content of the date pits. For the consumer panel, the color and the off-odors were improved, and the addition of 1.5% and 3% date pit in cooked burgers obtained similar scores. Based on the obtained results, the new ingredient from date pit may have potential preservative properties for enhancing stability during shelf life and could improve the composition of bioactive compounds (fiber and phenolic content) of beef burgers.

The biochemical composition, secondary metabolites (phenolic compounds, flavonoids) and antimicrobial potential of different varieties of Emirati date (Phoenix dactylifera L.) pits were investigated. Total phenolic acids (TPC) and total flavonoid contents (TFC) of the different date pits were measured using a Folin-Ciocalteau reagent. Different organic solvents [(n-hexane; H 2 O: EtOH (1:1); ethyl acetate; acetone: Water (1:1); and methanol: Chloroform (1:1)] were compared to evaluate the phytotoxicity of Ajwa, Fard, Khalas, Khodari, Abu Maan, Lulu, and Mabroom date pits. The antimicrobial activity of the date pit extracts were evaluated by means of agar-well diffusion assay on Staphylococcus aureus (ATCC 29123), Escherichia coli (ATCC 25922) and Candida albicans (ATCC 66027). Minimum inhibitory concentrations (MICs) were measured following clinical laboratory standardization institute (CLSI) protocol. The biochemical analyses of date pits indicate that TPC were ranged from 7.80 mg of equivalent gallic acid⁄100 g dry weight in Ajwa to 4.65 mg in Mabroom. The TFC were ranged between 1.6-4.54 mg of equivalent catechin⁄100 g dry weight. Ajwa pit extract showed good quality traits (higher protein, lower ash content, and intermediate dietary fiber). The results indicate that the ethyl acetate extract of Khalas and Khodari inhibited S. aureus with an inhibition zone diameter of 20 mm and MIC of 10 mg/mL. Abu Mann pit extract inhibited the S. aureus and also decreased the population of E. coli. The diameter of inhibition zone was 15, 16, and 18 mm after treatment with Ajwa extracts, while the MICs were 7.5 and 5 mg/mL. The MeOH: CFM extract of Abu Mann and Ajwa was more potent against E. coli bacteria than any other extract. This work demonstrates that the Emirati date pits extract has antimicrobial (antibacterial, antifungal) potential and can be used as phytotoxic natural compounds.

This nonrandomized controlled trial determined the effects of Phoenix dactylifera palm date (Ajwa) intake on the number of infections and hospitalizations associated with fever, neutropenia, and mortality of pediatric cancer patients admitted between 2008 and 2017 to King Abdulaziz University Hospital (Jeddah, Saudi Arabia). Patients were eligible to be enrolled if they fulfilled the inclusion criteria, were not allergic to Ajwa, and were not enrolled in another study. Of 200 screened patients, 56 were included and 144 were excluded. Of the 56, 26 agreed to take Ajwa, and 30 served as controls. Both groups were assessed based on infection rates, frequency of hospital admissions for fever and neutropenia, and mortality rate. Background information regarding demographics, clinicopathological data, and treatment options was documented. Supplementation of Ajwa significantly reduced hospital admissions (for fever-associated neutropenia) and infections (P =.009 and P <.001, respectively). Off-treatment did not significantly differ between the Ajwa and control groups. The Ajwa group had a better survival rate in comparison to the non-Ajwa group (stratified log-rank P =.005), where the main cause of death of patients in the non-Ajwa group was disease progression associated with infections (77%). In summary, Ajwa intake during the standard treatment of pediatric cancer patients improved their treatment outcome.

The present work aims to study the possibilities of developing silver nanoparticles using natural extracts of grape pomace wastes originating from the native variety of Fetească Neagră 6 Șt. This study focused on investigating the influence of grape pomace extract obtained by two different extraction methods (classical temperature extraction and microwave-assisted extraction) in the phytosynthesis process of metal nanoparticles. The total phenolic content of the extracts was assessed using the spectrophotometric method with the Folin–Ciocâlteu reagent, while the identification and quantification of specific components were conducted through high-performance liquid chromatography with a diode array detector (HPLC-DAD). The obtained nanoparticles were characterized by UV–Vis absorption spectroscopy, X-ray diffraction (XRD), and transmission electron microscopy (TEM), along with assessing their antioxidant and antimicrobial properties against Gram-positive bacteria. The data collected from the experiments indicated that the nanoparticles were formed in a relatively short period of time (96 h) and, for the experimental variant involving the use of a 1:1 ratio (v/v, grape pomace extract: silver nitrate) for the nanoparticle phytosynthesis, the smallest crystallite sizes (from X-ray diffraction—4.58 nm and 5.14 nm) as well as spherical or semispherical nanoparticles with the lowest average diameters were obtained (19.99–23 nm, from TEM analysis). The phytosynthesis process was shown to enhance the antioxidant properties (determined using the DPPH assay) and the antimicrobial potential (tested against Gram-positive strains) of the nanoparticles, as evidenced by comparing their properties with those of the parent extracts; at the same time, the nanoparticles exhibited a selectivity in action, being active against the Staphylococcus aureus strain while presenting no antimicrobial potential against the Enterococcus faecalis strain.

This study explored the impact of date palm seeds ethanolic extract (DSEE) on the microbiological, physicochemical, and sensory qualities of chicken breast meat kept refrigerated at 4 °C. DSEE was applied at 0.156% (DSEE1), 0.312% (DSEE2), and 0.624% (DSEE4). Microbiological parameters, chemical stability, and sensory features of DSEE were monitored for 14 days at refrigerated conditions (4 °C). DSEE considerably (p < 0.05) decreased lipid/protein oxidation processes. Interestingly, at 14 days, DSEE at 0.624% delayed microbial growth. Moreover, the addition of 0.312% (DSEE2) and 0.624% (DSEE4) and storage time substantially affected the sensory (appearance, odor, color, and overall acceptability) parameters of chicken breast meat. By expertly employing chemometric techniques such as principal component analysis (PCA) and heat maps, the acquired evidence brought useful information to regroup all samples and to associate microbiological and oxidation characteristics to organoleptic attributes using correlation models. PCA and heat maps provided effective information to differentiate all samples and relate lipid and protein oxidative processes and microbiological properties to sensory parameters. The obtained findings contribute to a better knowledge of the impact of chemical and microbial alterations on sensory quality in fortified meat products. This study displayed the potential functional and economic benefits of using DSEE as an encouraging component in chicken meat preservation.

Phoenix pusilla (Arecaceae), commonly known as "small wild date palm", is regarded as one of the underutilized fruit crops in South India. Methanol extract of P. pusilla ripened fruits (PPRF) was analyzed for in vitro porcine pancreatic alpha-amylase (PPAA) and rat small intestine alpha-glucosidase (RIAG) inhibition activities, and through gas chromatography-mass spectrometry (GC-MS) analysis. The GC-MS analysis showed the presence of 25 phytoconstituents from PPRF which was further assessed on the docking behavior of five targeted enzymes diabetes mellitus (DM) namely (i) human aldose reductase, (ii) protein tyrosine phosphatase 1B, (iii) pancreatic alpha-amylase, (iv) peroxisome proliferator-activated receptor gamma, and (v) dipeptidyl peptidase IV by using the AutoDock Vina method. In addition to this physicochemical, bioactivity score, absorption, distribution, metabolism, excretion, and toxicity (ADMET) analysis was performed using the Molinspiration and pkCSM free online servers. Methanolic extract of PPRF showed 50% inhibition concentration (IC 50) at 69.86 and 72.60 μg/ mL levels against PPAA and RIAG enzymes activities, respectively. Interestingly in the present study, GC-MS analysis showed the presence of 25 phytoconstituents from PPRF. Physicochemical analysis of PPRF has exhibited that 13 ligands have complied well with Lipinski's Rule of Five (RoF). With regard to ADMET analysis, one ligand (9,12-octadecadienoic acid [Z,Z]) has predicated to possess both the hepatotoxicity (HT) and skin sensitization (SS) effect. The docking studies showed that 1-formyl-2,5-dimethoxy-6,9,10-trimethyl-anthracene exhibited the maximum atomic contact energy (ACE) for all the five target enzymes of DM. Thus, the current study suggested that the methanolic extract of PPRF and its phytoconstituents could be considered as potent antidiabetic agents.

Humans cultivate plants for their daily commodities, like food and medicines. Innumerable varieties of crops and plant-derived products like cotton, fruits, vegetables, grains, pulses, and oils have been developed. A variety of seed oils have been used by humankind in dietary supplements and are regarded as feedstock for the production of biofuels. Date palm (Phoenix dactylifera L.) is one such plant used in the production of oil. Date palm is a commercial fruit that is primarily cultivated in South Mediterranean countries. Date palm fruit and its processed products such as jams, jellies, and syrup are globally consumed. However, tons of seed waste is generated after processing and raises environmental problems due to poor seed waste disposal practices. Scientific reports suggest that date palm seed oil is rich in minerals, fatty acids, and various phytochemicals like phenols, flavonoids, sterols, and tocopherols. These bioactive molecules possess significant pharmacological activities like antidiabetic, anti-inflammatory, antioxidant, antimicrobial, and hepatoprotectivity. This chapter summarizes the phytochemicals present in date palm seed oil, discusses the fatty acid composition in various date palm cultivars worldwide, and highlights the pharmacological activities exhibited by date seed oil. The chapter also discusses the effective utilization of date seed oil in the food and pharmaceutical industry and the seed oil by-products in biofuel production.

The abusive use of antibiotics causes the destruction of intestinal flora and the proliferation of antibiotic-resistant pathogens. Date palm is used in traditional medicine in the Saharan regions due to its biological properties. The study aimed to identify the phytochemical composition and assess the antibacterial activity of the methanolic extracts of three date cultivars from Algeria. Their total phenolic, flavonoid, and flavonol contents were measured spectrophotometrically. The phytochemical screening was conducted by HPLC fingerprinting using twenty-three pure phenolic compounds as standards. The antibacterial activity against pathogenic bacterial species was assessed using the disk diffusion method. The colorimetric methods showed that the total phenolic, flavonoid, and flavonol contents ranged from 2.13 ± 0.09 to 2.67 ± 0.02 mg GAE/100 g DW, 1.33 ± 0.21 to 1.55 ± 0.13 mg CEQ/100 g DW, and 0.41 ± 0.23 to 0.47 ± 0.05 mg REQ/100 g DW, respectively. HPLC fingerprinting showed that the extracts of date cultivars served as an excellent source of bioactive compounds (gallic acid, tannic acid, ferulic acid, vanillin, caffeine, quercetin, luteolin, rutin, aspegenin, isorhamnetin, and hesperidin). They also exhibited an antibacterial potential with an inhibition zone diameter ranging from 8.40 to 12.50 mm. The results clearly demonstrate the antibacterial potency of date palm fruits, which could be attributed to their considerable content of phenolic compounds such as gallic acid, rutin, quercetin, and luteolin.

Date palm tree (Phoenix dactylifera) has traditionally been grown in South-West Asia and North Africa, principally for date fruit consumption. Nevertheless, its cultivation has recently spread to other areas of America, sub-Saharan Africa, Oceania and Southern Europe. During date fruit processing, several by-products are generated, like low-quality dates, pits, leaves and pollen. These wastes, together with the date fruit, constitute an important source of biocomponents such as hydroxycinnamic and hydroxybenzoic acids, flavonoids, tannins, carotenoids, tocopherols, tocotrienols, phytosterols and phytoestrogens. This review provides detailed information about the sensory properties, nutritional profile and biocompounds with health-promoting properties present in date fruit and its by-products. Furthermore, recent findings regarding the potential of these products to develop new functional foodstuffs was also highlighted. Several studies have reported that the date fruit and its by-products present an outstanding richness in bioactive compounds with potential healthy properties that make them suitable to be used as nutraceutical ingredients in several foodstuffs. Their incorporation in the formulation of foods would contribute to cover the increasing demand of consumers by products elaborated with natural ingredients. Moreover, an important aspect to take into account is that food matrixes are an excellent vehicle for the availability of biomolecules present in the date palm products.

Background: Phoenix dactylifera fruit has been widely reported for its effective anti-inflammatory properties. Therefore, the effect of P. dactylifera on immune responses was evaluated in Aeromonas hydrophila infected Clarias gariepinus. Methods: P. dactylifera fruit powder was used as feed inclusion at 0 (control), 0.5, 1.0 and 2.0% concentrations to the pelleted fish diet of C. gariepinus juveniles. A total of 75 fish were divided into fourgroups (n=15) . The fish were fed with the formulated feed twice a day (08:00 h and 17:00 h), and terminated 24 h before the commencement of the microbial inoculation with inactivated Aeromonas hydrophila bacteria. The fish were later challenged with active Aeromonas hydrophila after seven weeks of experimental feeding. Blood samples were collected from fish while haemagglutination and phagocytic assays were used to determine the antibody titres and phagocytic action of the immune cells, respectively. Then, the micronucleus assay was used to determine the chromosomal damage effect of Aeromonas hydrophila pathogen on exposed C. gariepinus. Results: After the challenge, the groups fed with 0.5 and 2.0% date showed significantly (p˂0.05)elevated level of immune responses with antibody titres of 231.49±77.06 and 257.18±51.37, and phagocytic activity values of 0.07±0.01 and 0.04±0.00, respectively. The clastogenic effect of A. hydrophilaon the peripheral blood of infected C. gariepinus was observed, this was significantly reduced in 2% P. dactylifera fed group. Also, increase white blood cell count was observed in the C. gariepinus group fed with 0.5% date supplement. A higher lymphoid organ index was also observed in fish fed with the supplemented diet, as compared to the control. Conclusions: These results indicate that P. dactylifera fruit powder enriched diet showed an immune-boosting and reduction of the DNA damaging effect in bacteria-infected C. gariepinus

Ethnopharmacological relevance: Over the past thousand years, Islamic physicians have collected cultural, philosophical, sociological and historical backgrounds for understanding diseases and medications. The Prophet Mohammed (Peace Be Upon Him (PBUH) said: "There is no disease that Allah has created, except that Allah also has created its cure." Therefore, Islamic scholars are encouraged to explore and use both traditional and modern forms of medicine. Aim of the study: (1) To identify some of the medicinal plants mentioned in the Holy Qur'ân and Ahadith textbooks of the period 700-1500 AD; (2) to compare them with presently used traditional medicines; (3) to evaluate their value based on modern research; and (4) to investigate the contributions of Islamic scholars to the development of the scientific branches, particularly medicine. Materials and methods: A literature search was performed relating to 12 medicinal plants mentioned in the Holy Qur'ân and Ahadith using textbooks, Al-Azhar scholars, published articles, the plant list website (http://www.theplantlist.org/), the medicinal plant names services website (http://mpns.kew.org/mpns-portal/) and web databases (PubMed, Science Direct, and Google Scholar). Results and discussion: The Islamic Golden Age was a step towards modern medicine, with unique insights and multi-disciplinary aspects. Traditional Islamic Medicine has had a significant impact on the development of various medical, scientific and educational activities. Innumerable Muslim and non-Muslim physicians have built on the strong foundation of Traditional Islamic Medicine by translating the described natural remedies and effects. The influences of different ancient cultures on the traditional uses of natural products were also documented in Islamic Scriptures in the last part of the second millennium. The divine teachings of Islam combine natural and practical healing and incorporate inherited science and technology. Conclusion: In this review, we discuss Traditional Islamic Medicine with reference to both medical recommendations mentioned in the Holy Qur'ân and Prophetic Traditional Medicine (al-Tibb al-Nabawi). Although the molecular mechanisms and functions of some of the listed medicinal plants and their derivatives have been intensively studied, some traditional remedies have yet to be translated into clinical applications.

Date palm fruits and their seeds are excellent sources of dietary fiber (DF). Date fruits contain 8.1–12.7 % Total DFs (of which 84–94 % is insoluble and 6–16 % soluble DF) and is very rich in phenolic antioxidants (1–2 %). Date fruit fibers are composed of cellulose and NSP. Moreover, date DF has important functional properties, such as water-holding capacity and oil-holding capacity. Date seeds contain about 15 % fiber, characterized by a high level of water-insoluble mannan fibers. It has been suggested that date fruits and seeds can be exploited in some food applications. In order to improve fiber yields, pretreatment procedures can be applied, which give excellent results in the case of date palm fibers. Date fruits are widely available in the global market, but there is still room for improvement, particularly in the revalorization of date processing waste, and secondary cultivars. The incorporation of date fruits and seeds as food ingredients would promote the presence of dates in the modern's consumer shopping basket. Present knowledge about different aspects of date DF, and suitable extraction methods and applications of date fiber (flesh and seed), will be the focus of this report.
... The antimicrobical activity of Palm pollen draws from containing the auxiliary anabolic materials as sterols, flavonoids ,alkaloids and saponoids, coumarin and pectin [9] , and the activity of the alcoholic extract may draw from the capacity of some material melting in alcohol more than in water. [19] appeared that the activity of the Palm pollen extract against the bacterial species draw from its containing the flavonoids like querectin, and [20] indicated that the Palm pollen extract has an activity in inhibiting certain strains of bacteria including E.coli and staphylococcus as well as the fungus Fusarium oxysporium that is one of the morbigenous fungus to plant and isolated from soil and that because the pollen is rich with Cinnamic , flavonoid and Gallic acid , whreas [21] showed there was no important role for the aqueos extract of the Palm pollen against the numerous practical bacterial species. [11] found that the crud ethanol extract had an important role in inhibiting numerous negative and positive gram bacterial species as Pseudomonas aeroginosa, Escherichia coli , Bacillus subtillis, streptococcus pyogenes, Staphylococcus aureus and Shiglla flexeneri. ...

The aim of the present study was to investigate the potential antimicrobial activity of Olea europaea fatty oil against a collection of bacterial (Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa) and fungal (Candida albicans) clinical isolates. The antimicrobial and antibiofilm activity were evaluated by broth microdilution method for establishing the minimal inhibitory concentration (MIC) and microtiter assay for determining the minimal biofilm eradication concentration (MBEC). Some of the potential microbial targets of the fatty oil were investigated by flow cytometry (FCM). The results obtained hereby revealed that Olea europaea fatty oil inhibited microbial planktonic growth (MICs values of 5.23-41.8 mg/ mL) and biofilm development on inert substrata (MBEC values of 1.31-20.9 mg/ mL). The FCM measurements confirmed that the analyzed oil induced microbial membrane damages and inhibited microbial efflux pump activity.

The pharmaceutical research sector’s inability to develop new drugs has made it challenging to combat microbial resistance. Secondary metabolites from plant extracts have been identified as potential protective agents against multi-drug-resistant bacteria. This study aimed to analyze hydro-ethanol extracts’ antioxidant and antimicrobial activities from various parts of the Zahidi date (whole fruit, pit powder, and flesh). Phytochemical screening of phenolic and flavonoid compounds was performed using high-performance liquid chromatography (HPLC). Total phenolic and flavonoid compounds were extracted at their maximum levels, 71.89 mg/100 g and 843.06 mg/100 g, respectively, using EoH 60%. The whole fruit had the highest concentration of flavonoid quercetin (0.83 μg/g) and phenolic compoundsinapic acid (20.03 μg/g) at the same concentration. The findings from the broth micro-dilution method showed that the whole fruit had the strongest antimicrobial effects at 60% EoHagainst Salmonella typhi (30 mg/ml), Helicobacter pylori (27 mg/ml), Escherichia coli (22 mg/ml), and Staphylococcus aureus (44 mg/ml). Zahidi whole fruit extracts showed higher antioxidant potential at EoH 60% using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) scavenging potential (78%) and ferric-reducing antioxidant power. Principal component analysis (PCA) revealed a significant negative correlation between antioxidant activity and the minimum inhibitory concentration (MIC). Evidence from this study highlights the considerable antioxidant and antimicrobial properties of Zahidi date fruit, suggesting its potential use in producing natural drugs and value-added foods to counteract contagious diseases.

Introduction et objectifs Les dattes, un fruit miraculeux cité dans le Coran constitue un aliment de base des populations des zones désertiques vu ses valeurs nutritionnelles et biologiques élevées d’où la nécessité de son exploitation dans différents domaines. Dans cette optique, la présente étude cible une évaluation qualitative et quantitative de différents composants de la datte en vue de sa valorisation particulièrement comme alternative naturelle à l’antibiothérapie. Matériels et Méthodes Une caractérisation morphométrique (poids et taille) et physicochimique (pH, acidité titrable, humidité, cendres) de douze (12) variétés de dattes algériennes a été réalisée. Par la suite, différents composants (pulpe, noyaux et mixture) de trois variétés choisies ; Tamesrit, Deglet Nour et H’mira ont servi au calcul de la teneur en polyphénols totaux et l’évaluation de l'effet antibactérien de leurs extraits méthanoliques vis à-vis S. aureus et E. coli par la technique de la microdilution où les CMIs et les CMBs ont été déterminées. Résultats et discussion Les analyses morphométriques et physicochimiques ont montré des différences hautement significatives (P<0.001) entre les variétés quel que soit le paramètre étudié où la majorité des cultivars ont présenté un bon caractère. Pour les trois variétés, le taux des polyphénols totaux varie très significativement (P<0.001) et est plus important dans les extraits méthanoliques (24.25 à 156.84 mg EAG/100g d’extrait) que les extraits aqueux (20.24 à 113.69 mg EAG/100g d’extrait). Un effet antibactérien plus important a été noté dans les noyaux des extraits méthanoliques avec des CMIs et des CMBs allant de <0.61 à 1.17mg. Cet effet était particulièrement intéressant chez les variétés H’mira et Tamesrit pour inhiber la croissance des deux souches. Conclusion Les dattes possèdent des propriétés antibactériennes intéressantes qui méritent d’être exploitées.

Many natural candidates of plant origin like fruits, fruit skin, fruit seeds, barks etc. have been studied to determine their antibacterial activity. This study came for the rapidly increasing antibiotic resistant bacteria which are now becoming difficult to deal with. So natural phytochemicals are screening out to find the effective phytochemicals which can act against these antibiotic resistant bacteria. In the current study we chose five different dates (ajwa, maryam, sagai, safawi, amber) and the leave of date tree to determine their efficacy against five clinical isolates (Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Klebsiella pneumoniae, and Enterococcus spp.). Dates and leaves samples were first homogenized directly for the preparation of crude extract and subjected to antibacterial activity test following agar well diffusion method. Sun dried samples were powdered and then subjected to ethanol, methanol and aqueous extract production. Clinical isolates were used to determine the antibacterial activity of the extracts against them. The isolates were found to be multi drug resistant. Out of twenty eight antibiotics, Pseudomonas aeruginosa was resistant to ten antibiotics and Enterococcus spp. was resistant to eight antibiotics. Rather than the crude extracts of the fruits ad leaves, ethanol, methanol extract showed much higher antibacterial activity towards multi drug resistant pathogenic bacteria. Aqueous extract were found to exhibit the lowest degree of effectiveness compared to other extracts. Methanol extracts exhibited higher efficacy than ethanol extracts. Extracts of amber showed highest results whereas other dates showed nearly similar results on an average. As the clinical isolates were able to be inhibited by the extracts, they can be used as an alternative for treating infections caused by these bacteria.
