... Modern techniques, such as supercritical fluid extraction (SFE), microwave-assisted extraction (MAE), pressurized fluid extraction (PFE), and ultrasonic-assisted extraction (USAE), are used in the extraction process [8]. Recent studies have revealed more effective extraction methods, such as microwave-assisted and ultrasonic-assisted extraction, which provide high efficiency in yielding bioactive compounds from Jasmine leaves [9,10]. While microwave-assisted extraction has merits for optimizing high phenolic compounds, its limitation is that the low boiling point of bioactive compounds can render them inactive. ...
This study focus was on the optimization and evaluation of phenolic and flavonoid compounds in Jasmine leaf extract using microwave and ultrasonication-assisted extraction methods. Bioactive compounds, including phenolic and flavonoid compounds, were extracted by evaluating various process parameters. The optimized leaf extract was assessed based on solute-to-solvent ratio, microwave power, extraction time, and frequency. The optimized results from microwave-assisted extraction yielded a total phenolic content of 180.05 mg/g and a total flavonoid content of 60.5 mg/g in the extract. In contrast, the ultrasonication-assisted extraction achieved a higher yield, with a total phenolic content of 210.8 mg/g and a total flavonoid content of 90.4 mg/g in the extract. The extract contained significant amounts of gallic acid (13.49%), rutin (37.37%), and octadecenoic acid (23.98%). Additionally, esters, aromatic compound derivatives, and unsaturated fatty acids were highlighted in the extract owing to their potential antioxidant and antimicrobial applications. The antioxidant activity of Jasmine leaf extract was evaluated using both extraction methods, with the ultrasonication-assisted extract showing significantly higher effectiveness. The extraction process was optimized using response surface methodology with a face-centered composite design model. This study provides new data on the chemical composition of Jasmine leaf extract and its sources, offering valuable insights for various applications. However, detailed investigations are still needed to isolate compounds from optimized extracts for various applications.

Scientists have been working on developing a green bio-TENG for portable remote devices, including wearables in the biomedical sector. The process involves obtaining pectin, a green material with anti-microbial properties, as a Triboelectric material. This study focuses on the extraction of essential oil (EO) and pectin from Assam lemon peel simultaneously. A single-step strategy was optimized using a central composite design-based response surface approach. The extracted pectin yielded 4.19 ± 0.31 % and 11.53 ± 0.11 %, respectively. GC-MS analysis revealed 52 volatile components in the Assam lemon EOs, with limonin being 94.47 % and β-Bisabolene being 1.26 %. Only khusilal was found in the EOs, a rare discovery in the scientific domain. The extracted pectin showed good purity and antimicrobial properties. The in vitro activities of the citrus EO against microbial cultures revealed its activity in controlling and eradicating bacterial and fungal growth. Hydro distillation followed by enzyme treatment is a promising approach that combines two separate extraction procedures. The produced biopolymer showed the generation of electrical signals under minimal pressure and stretching and prevented microbial degeneration when applied to a nanogenerator.

Hydrodistillation (HD) systems have been popular for essential oils extraction from medicinal and aromatic plants for several decades. Nevertheless, they substantially consume thermal or electrical energy and have a visible carbon footprint on the environment. This article describes a state‐of‐the‐art review of the HD systems used for essential oil extraction to examine their effectiveness. From this study, it has been found that, for a microwave‐assisted system, the yield of an essential oil varies from 0.079% to 8.62%. The microwave‐assisted hydrodistillation (MAHD) system yields 32% more than a conventional HD system. The average extraction time saved using the MAHD system is 67.17% compared with the traditional one. Ohmic‐assisted HD system is better than the microwave‐assisted and conventional HD system, with an 18.04% enhancement in the yield. During this study, it is also investigated that for the distillation system operating at atmospheric pressure, the extraction temperature ranges from 80°C to 120°C. This temperature can easily be attained in a solar hydrodistillation system. Several investigators have demonstrated the use of solar energy for essential oil extraction. However, these systems mostly use a concentrating collector, henceforth found bulky and expensive.

Essential oils (EOs) and Plant extracts (PEs) are gaining attention as eco-friendly alternatives to synthetic fungicides for the management of soil-borne fungi related to root rot and the wilt of marigolds. Here, EOs of Cinnamomum zeylanicum (cinnamon), Mentha piperita (peppermint), Syzygium aromaticum (clove), Thymus vulgaris (thyme), PEs of Cymbopogon citratus (lemongrass), Lantana camara (lantana), Ocimum basilicum (basil), and Zingiber officinales (ginger) were first evaluated in vitro for their inhibitory activity against the mycelium growth of the root rot and wilt fungi of marigold: Rhizoctonia solani, Sclerotinia sclerotiorum, Fusarium oxysporum, and F. solani, and in vivo for their activity in reducing disease progression. The results show that all EOs had a strong inhibitory activity on the mycelium growth of pathogens. Maximum inhibition of mycelium growth was achieved at a concentration of 1 mL/Lof S. aromaticum, C. zeylanicum, and M. piperita. The inhibition values were 100, 80.9, and 72.4% for F. solani, 100, 81.1, and 70% for S. sclerotiorum, 90.2, 79.4, and 69.1% for F. oxysporum, and 85.4, 78.2, and 68.7% for R. solani, respectively. Regarding plant extracts, the highest inhibition of mycelium growth was attained at a concentration of 20% of Z. officinales, C. citratus, and L. camara. The inhibition values were 77.4, 69.1, and 60.6% for F. solani, 76.5, 67.2, and 58% for S. sclerotiorum, 73.5, 68.2, and 56.3% for F. oxysporum, and 72, 64.8, and 55.2% for R. solani, respectively. In pot experiments, the application of EOs and PEs showed high efficiency in suppressing root rot and wilt of marigold at all concentrations used, especially at 3 mL/L for seed soaking (along with 1.5 mL/L for foliar spraying) for S. aromaticum, C. zeylanicum, and M. piperita EOs, and (40% for seed soaking along with 20% for foliar spraying) for Z. officinales, C. citratus, and L. camara PEs. All the treatments applied in the field greatly reduced the diseases in both seasons, especially S. aromaticum EO, C. zeylanicum EO, Z. officinales PE, and carbendazim treatments. This was accompanied by a significant improvement in morphological, yield, and phytochemical parameters of marigold as well as a significant increase in the activity of defense-related antioxidant enzymes. Overall, essential oils and plant extracts can be used effectively to control root rot and wilt in marigold as sustainable and eco-friendly botanical biofungicides.
... The operating pressure of supercritical carbon dioxide extraction was also enormously high, up to 300 bar, while the operating pressure of subcritical HFC-134a extraction was always below 10 bar. On the other hand, the extraction yield from hydrodistillation extraction was similar to subcritical HFC-134a extraction at approximately 0.09% [32], but the maximum temperature during the extraction process of subcritical HFC-134a extraction was only 40 • C. At a low extraction temperature, many volatile compounds seemed not to be damaged by heat. ...
... The results of volatile compounds from GC-MS showed that common components such as indole, benzyl acetate and benzyl alcohol could be found in jasmine essential oil, similarly to previous studies [9,37]. In addition to hydrodistillation, a traditional extraction method, linalool, muurolol [32], and α-farnesene [39] were the major volatile compounds that were combined to form the jasmine smell. Most of the major volatile compounds were observed in solvent extraction studies and appeared to differ from different raw material sources [31,40,41]. ...
Essential oil from Jasminum sambac flowers has demonstrated the potential of antioxidant and antimicrobial properties. However, jasmine flowers contain only a small amount of essential oil; therefore, subcritical fluid extraction (SFE) with HFC-134a, one of the effective extraction methods for flower extraction, was performed in this study. The percentage of overfilled solvent and storage time of the flowers were varied during the extraction. Antioxidant potential, antimicrobial potential and tentative volatile compounds were investigated in this study to observe the quality of the essential oil. It was discovered that a greater amount of overfilled solvent resulted in thicker essential oil and a longer storage time resulted in a lower amount of total oil yield. It could be seen that almost all extraction conditions did not have any significant difference in antioxidant and antimicrobial potential. The essential oil contained primary compounds such as indole, 9-tricosene, α-farnesene, muurolene, and benzyl alcohol. This study led to the conclusion that the amount of overfilled solvent from SFE affected the thickness of jasmine essential oil and its tentative volatile compounds. The longer storage time caused the significantly lower essential oil yield, but changing the extraction conditions had no significant effect on antioxidant or antimicrobial potential.
... Approximately 100 g of dry, crushed celery fruits were extracted by hydro-distillation for 6 h using a Clevenger-type apparatus based on the method described by Phu et al. [107]. The obtained essential oil samples were dehydrated over an anhydrous sodium sulphate (Na 2 SO 4 ) and then stored in dark sealed vials at 4 • C. The percentage of essential oil was calculated as the following equation: The leaf pigments of photosynthesis were measured according to the method described by Wellburn [108]. ...
The present study aimed to investigate the potentiality of certain biocontrol agents, namely Bacillus subtilis, B. pumilus, B. megaterium, Pseudomonas fluorescens, Serratia marcescens, Trichoderma album, T. harzianum and T. viride, as well as the synthetic fungicide difenoconazole to control celery powdery mildew caused by Erysiphe heraclei DC, in vitro (against conidia germination and germ tube length of E. heraclei) and in vivo (against disease severity and AUDPC). In vitro, it was found that the antifungal activity of the tested biocontrol agents significantly reduced the germination percentage of the conidia and germ tube length of the pathogen. The reduction in conidia germination ranged between 88.2% and 59.6% as a result of the treatment with B. subtilis and T. album, respectively compared with 97.1% by the synthetic fungicide difenoconazole. Moreover, the fungicide achieved the highest reduction in germ tube length (92.5%) followed by B. megaterium (82.0%), while T. album was the least effective (62.8%). Spraying celery plants with the tested biocontrol agents in the greenhouse significantly reduced powdery mildew severity, as well as the area under the disease progress curve (AUDPC), after 7, 14, 21 and 28 days of application. In this regard, B. subtilis was the most efficient followed by B. pumilus, S. marcescens and B. megaterium, with 80.1, 74.4, 73.2 and 70.5% reductions in disease severity, respectively. In AUDPC, reductions of those microorganisms were 285.3, 380.9, 396.7 and 431.8, respectively, compared to 1539.1 in the control treatment. On the other hand, the fungicide difenoconazole achieved maximum efficacy in reducing disease severity (84.7%) and lowest AUDPC (219.3) compared to the other treatments. In the field, all the applied biocontrol agents showed high efficiency in suppressing powdery mildew on celery plants, with a significant improvement in growth and yield characteristics. In addition, they caused an increase in the concentration of leaf pigments, and the activities of defense-related enzymes such as peroxidase (PO) and polyphenol oxidase (PPO) and total phenol content (TPC). In conclusion, the results showed the possibility of using tested biocontrol agents as eco-friendly alternatives to protect celery plants against powdery mildew.

Essential oils of five different common spices in cinnamon, cumin, cardamom, wisteria and coriander were extracted by hydrodistillation and steam distillation. The yield percentages of oils extracted by each method were calculated and compared. The yield percentages of cinnamon, cumin, cardamom, wisteria, and coriander oils obtained by hydrodistillation are 1.9, 2.0, 2.8, 1.7 and 1.0%, respectively. The yield percentages of cinnamon, cumin, cardamom, wisteria, and coriander oils obtained by steam distillation are 0.7, 0.8, 1.2, 0.5 and 0.5%, respectively. Hydrodistillation provided higher yield compared to steam distillation. The antioxidant activity of each spice was determined in terms of antioxidant activities due to volatile oil and non-volatile components of spice by DPPH radical scavenging activity method. The highest percentage antioxidant activity due to volatile oil was of cinnamon with 69.27%. The highest percentage of antioxidant activity due to non-volatile component of spice was of coriander with 90.79%. The composition of fresh spice extracts and essential oil of each spice was determined by gas chromatography-mass spectrometry (GC-MS). The most common components found in spice samples were D
... Due to the presence of an excess amount of water, thermal stress occurs caused by the rapid heating of the solution on account of the effective absorption of microwaves by water [25]. On the other hand, an insufficient amount of water is unable to melt adhesives, the essential oils are not being released and target extraction is incomplete [26]. Therefore, 1:10-1:15 was chosen as a suitable material-to-water range for further optimization. ...
The main goal of the research was to optimize microwave-assisted simultaneous distillation and extraction (MA-SDE) using response surface methodology (RSM), based on Box–Behnken design (BBD). A process was designed to extract the essential oil from the leaf sheath of Siam cardamom. The experimental data were fitted to quadratic equations, and the experiment conditions for optimal extraction of 1,8-cineole were extraction time 87.68 min, material-to-water ratio 1:13.18 g/mL and microwave power 217.77 W. Under such conditions, the content of 1,8-cineole was 157.23 ± 4.23 µg/g, which matched with the predicted value. GC–MS results indicated the presence of predominant oxygenated monoterpenes including 1,8-cineole (20.63%), iso-carveol (14.30%), cis-p-mentha-1(7),8-dien-2-ol (12.27%) and trans-p-2,8-menthadien-1-ol (9.66%), and oxygenated contents were slightly higher in the MA-SDE and extraction compared to usual SDE. In addition, the essential oil extracted by MA-SDE exhibited strong antibacterial effects against the tested Gram-positive bacteria. Scanning electron micrographs provided more evidence of destruction of the leaf sheath treated by MA-SDE. Conclusively, microwave-assisted simultaneous distillation and solvent extraction appear to be an effective technique for the separation of essential oils enriched 1,8-cineole from Siam cardamom leaf sheath in a shorter time.
