Objective: Cistus creticus L. is widespread in the coastal regions of Türkiye. In this study, we investigated the cytotoxic, antiobesity, antimicrobial and antibiofilm properties as well as the total phenolic and flavonoid content of both aqueous and ethanolic extracts in vitro. Material and Method: Two different extracts were prepared from the flowering aerial parts of Cistus creticus using ethanol and water. The total phenolic content and total flavonoids were determined by the Folin-Ciocalteu method and the aluminum chloride colorimetry, respectively. The effect of extracts on the cell viability of 3T3-L1 was determined by methyl thiazole tetrazolium (MTT), and the evaluation of differentiation and the effects of the plant extracts on lipid accumulation in 3T3-L1 adipocytes was performed by Oil-Red O staining. In addition, MIC values and antibiofilm activities were also investigated. Result and Discussion: The total phenol content of the EtOH and water extract was determined to be 134.2849 mg GAE/g and 96.1803 mg GAE/g, respectively. The total flavonoids in the water and EtOH extracts were found to be 33.1942 mgQE/g and 22.8338 mgQE/g, respectively. The lowest MIC values were determined for the strains Bacillus subtilis DSM 1971, Bacillus licheniformis DSM 13 and Bacillus amyloliquefaciens DSM 7, while the highest MIC concentration was found for the strains Escherichia coli and Eenterococcus gallinarum. The MIC/16 concentration of Pseudomonas aeruginosa ATCC 27853 and Escherichia coli ATCC 25922 also proved to be effective in inhibiting biofilm formation. We observed that noticeable but not strong effects on lipid accumulation were observed in 3T3-L1 adipocytes treated with EtOH extract.

Cistus monspeliensis L. (C. monspeliensis) is used in Italian folk medicine. This study was performed to determine genotoxic and antigenotoxic effects of C. monspeliensis leaf extract against mitomycin C (MMC) using an in vitro cytokinesis-block micronucleus assay (CBMN) in the Chinese Hamster Ovarian K1 (CHO-K1) cell line. The phytochemical composition of C. monspeliensis extract was evaluated using an untargeted metabolomic approach by employing UPLC-PDA-ESI/MS. The automated in vitro CBMN assay was carried out using image analysis systems with a widefield fluorescence microscope and the ImageStreamX imaging flow cytometer. The phytochemical profile of C. monspeliensis extract showed, as the most abundant metabolites, punicalagin, myricetin, gallocathechin, and a labdane-type diterpene. C. monspeliensis, at the tested concentrations of 50, 100, and 200 μg/mL, did not induce significant micronuclei frequency, thus indicating the absence of a genotoxic potential. When testing the C. monspeliensis extract for antigenotoxicity in the presence of MMC, we observed a hormetic concentration-dependent effect, where low concentrations resulted in a significant protective effect against MMC-induced micronuclei frequency, and higher concentrations resulted in no effect. In conclusion, our findings demonstrate that C. monspeliensis extract is not genotoxic and, at low concentration, exhibits an antigenotoxic effect. In relation to this final point, C. monspeliensis may act as a potential chemo-preventive against genotoxic agents.
... A prior study demonstrated that the chemical composition and, hence, the biological properties of Cistus species were highly affected by many habitat factors and environmental conditions. Besides, no Cistus monograph was available despite the long traditional use of many Cistus species and their implication in diverse medicinal purposes (Lukas et al., 2021). Thus, more indepth investigations on Cistus species grown in different geographical regions are needed to provide guidelines for their pharmacological and nutraceutical applications. ...
... Phenolic acids and coumarins represented, respectively, 6%-9% and 3%-10% of the phytoconstituents in the three species. Lukas et al. (2021) proposed a classification of selected Cistus species, including C. creticus and C. salviifolius, into two main chemovariants: flavonol-rich, purple-flowered clade (C. creticus) and the more ellagitannin-rich, white-or whitish-pink-flowered clade (C. ...
... Lukas et al. 's (2021) classification is based on the chemical profile of leaves' aqueous extracts, while methanol was used to prepare the extracts in the present study, and, therefore, the extraction solvent might have affected compound recovery (Hemmer et al., 2024). In addition, Lukas et al. (2021) reported that the separation of the purpleflowered and the white-and whitish-pink-flowered clade was not entirely perfect, and more investigations are needed, as many Italian, Croatian, and Cypriot accessions of C. creticus exhibited comparatively high percentages of punicalagin derivatives (tannins). Considering the distribution of the other metabolites, four diterpenes, namely isoabienol and manool or 13-epimanool, sclareol, and labda-7,14-dien-13-ol, in addition to abscisic acid (a sesquiterpenoid phytohormone), were only identified in the C. creticus extracts. ...

Helianthemum nummularium (HN) and Helianthemum oelanticum subsp. incanum (HO) are plant species, among Cistaceae, that are highly distributed in the Mediterranean region. In the current study, extracts of the aerial parts from both species have been analyzed phytochemically. The non-polar extract analysis resulted in the identification of 15 compounds in each species, mainly terpene and fatty acid derivatives, through GC–MS. The methanolic extract analysis, conducted through UHPLC–MS/MS, led to the identification of 39 metabolites in HN and 29 in HO, respectively, the majority of which were phenolics. Among the identified compounds, several have also been isolated and structurally determined (from HN: rutin, linoleic acid, gallic acid, and isoquercetin, and from HO: quercetin-3-O-(2″-O-galloyl)-galactopyranoside, methyl gallate, catechin-3-O-glucopyranoside, and astragalin, while hyperoside, and cis- and trans-tiliroside have been determined in both species). Furthermore, the methanolic extracts of HN and HO displayed a high total phenolic content (177.2 mg GA/g extract and 150.6 mg GA/g extract, respectively) and considerable free-radical scavenging activity against the DPPH radical (94.6% and 94.0% DPPH inhibition, respectively). Antimicrobial testing showed stronger inhibition of HN against Gram (+) bacterial strains (MIC values 0.07–0.15 mg/mL), while both extracts exhibited low tyrosinase-inhibitory activity. Considering the lack of studies conducted on the chemistry and biological activities of the genus Helianthemum, the chemical characterization of extracts could contribute to new sources of bioactive metabolites to be explored and exploited for further potential applications such as food and/ or the cosmetic industry.

The objective of this study was to determine the optimal conditions for the recovery of bioactive and antioxidant compounds in aqueous solutions of Cistus creticus leaves and then employ the optimal extract for the enrichment of yogurt samples. The optimal conditions were established by a response surface methodology and were determined to be a liquid-to-solid ratio of 48 mL/g at 76 °C for 41 min. The optimum extract yielded TPC 157.17 mg GAE/g dw and TFC 2.38 mg QE/g dw, while FRAP and DPPH values were 1258.52 and 933.67 µmol AAE/g dw, respectively. HPLC-DAD was utilized to identify and quantify specific polyphenols, like myricetin rhamnoside, in the extract. The optimal extract was then added to yogurt desserts during their preparation at three different concentrations to study how the physicochemical characteristics of the yogurt, as well as the antioxidant capacity added during enrichment, were affected. Statistical analysis of the results was carried out in order to obtain more valid data. It seems that the most suitable concentration for yogurt fortification was 0.1% w/v of the extract as, at this concentration, the yogurts exhibited higher antioxidant capacity, and their physicochemical characteristics were improved.

Cistus parviflorus L. (Cistaceae) is a medicinal plant with several folkloric applications, including being used for urinary tract infections and as a food additive. In this study, the polyphenolic diversity and the antioxidant, antidiabetic, and antimicrobial activities of the C. parviflorus methanolic extract were evaluated. Spectrophotometric and HPLC-based analyses using standard polyphenolic compounds were conducted to measure the phenolics and flavonoids in the plant extract. The in vitro DPPH, ORAC, FRAP, and α-glucosidase assays were used to evaluate the plant’s antioxidant and antidiabetic activities. Furthermore, disc diffusion and MIC-based microdilution tests were applied to evaluate the antimicrobial activity of the plant against broad-spectrum microorganisms. The analysis revealed the existence of high phenolic and flavonoid quantities that were measured at 302.59 ± 0.6 μg GAE and 134.3 ± 0.5 μg RE, respectively. The HPLC-based analysis revealed the existence of 18 phenolic acids and 8 flavonoids. The major phenolic acid was ellagic acid (169.03 ppm), while catechin was the major flavonoid (91.80 ppm). Remarkable antioxidant activity was measured using three different assays: DPPH, ORAC, and FRAP. Furthermore, strong inhibition of α-glucosidase compared to acarbose was recorded for the plant extract (IC50 0.924 ± 0.6). The results showed that C. parviflorus’s extract had a strong anti-Escherichia coli effect with MIC value of 0.98 μg\mL and IZD value of 32.2 ± 0.58 mm compared to 25.3 ± 0.18 mm for gentamycin, the positive control. Moreover, Aspergillus niger, Aspergillus fumigatus, Staphylococcus aureus, Streptococcus pyogenes, and Salmonella typhimurium all showed significant growth inhibition in response to the extract, a result that may be related to the use of the plant in traditional medicine to treat urinary tract infections. The docking study indicated the higher binding affinity of the major identified compounds, i.e., ellagic acid, rutin, naringin, catechin, and punicalagin, to the S. aureus gyrase-DNA complex, which might suggest the possible mechanisms of the plant as antimicrobial agents.
... Regarding the main identified compound (i.e., myricetin rhamnoside), an increase of 869% was recorded [15]. Additionally, in comparison with another report that studied Mediterranean northern shore Cistus creticus L. from different countries, an increased extraction yield of about 175% and 155% was recorded for all myricetin derivatives and quercetin derivatives, respectively [37]. Next, we also evaluated the content of the three abovementioned extracts from the single-solvent extraction, in the same polyphenols (Table 4). ...

The aim of this study was to evaluate the efficiency of successive extraction (using solvents of increasing polarity, namely hexane, ethyl acetate, acetone, ethanol, and water) of polyphenols from Cistus creticus L. The results were compared with the ones obtained from a single-solvent extraction (ethanol, water, and 50% ethanol: water). According to the results, each solvent used for extraction had a significant effect on the yield of extracted polyphenols and the antioxidant activity of the extracts. The highest extraction yield for successive extraction was achieved with ethanol (95.33 mg GAE/g), whereas a comparable amount could also be extracted with 50% ethanol: water mixture single-solvent extraction (96.51 mg GAE/g). The ethanolic and aqueous extracts had the highest antioxidant activity as indicated by their lowest IC 50 values in the DPPH assay, specifically 350.99 µg/mL for ethanolic extract of successive extraction and 341.18 µg/mL for 50% ethanol: water mixture of single-solvent extraction, followed by the extract produced using acetone. However, the acetone extract contained more flavonoids than the other two extracts up to 28.03 mg QE/g. The results obtained were in line with those for the single-solvent extraction. It is concluded that using a range of solvents in succession is a more efficient way of extracting higher amounts of antioxidant compounds with varying antioxidant activity.
... Cluster 0, the smallest cluster with only 6% of the total articles (99 articles), brings together articles that deal mainly with the effect of tannins present in plants of the Cistus genus, especially C. ladanifer, that certain ruminants, such as goats, consume in their diet, since there are indications that relate the levels of these phenols with better health and quality of these animals' meat and milk [12][13][14][15]. Cluster 1, the second-largest cluster with 31% of the total articles (489 articles), groups articles that address the bioactive and medicinal properties of the extracts and essential oils obtained from Cistus, such as its antioxidant and antibacterial capacity [6,16,17].

Reviews have traditionally been based on extensive searches of the available bibliography on the topic of interest. However, this approach is frequently influenced by the authors’ background, leading to possible selection bias. Artificial intelligence applied to natural language processing (NLP) is a powerful tool that can be used for systematic reviews by speeding up the process and providing more objective results, but its use in scientific literature reviews is still scarce. This manuscript addresses this challenge by developing a reproducible tool that can be used to develop objective reviews on almost every topic. This tool has been used to review the antibacterial activity of Cistus genus plant extracts as proof of concept, providing a comprehensive and objective state of the art on this topic based on the analysis of 1601 research manuscripts and 136 patents. Data were processed using a publicly available Jupyter Notebook in Google Collaboratory here. NLP, when applied to the study of antibacterial activity of Cistus plants, is able to recover the main scientific manuscripts and patents related to the topic, avoiding any biases. The NLP-assisted literature review reveals that C. creticus and C. monspeliensis are the first and second most studied Cistus species respectively. Leaves and fruits are the most commonly used plant parts and methanol, followed by butanol and water, the most widely used solvents to prepare plant extracts. Furthermore, Staphylococcus. aureus followed by Bacillus. cereus are the most studied bacterial species, which are also the most susceptible bacteria in all studied assays. This new tool aims to change the actual paradigm of the review of scientific literature to make the process more efficient, reliable, and reproducible, according to Open Science standards.

In this study phytochemical compounds and antioxidant capacity, cytotoxic, antimicrobial and anti‐biofilm activities of hydroethanolic extracts of five Cistus species (C. creticus L., C. laurifolius L., C. monspeliensis L., C. parviflorus Lam. and C. salviifolius L.) distributed in Turkey were investigated. (+)‐catechin, epigallocatechin gallate, quercetin‐3‐O‐rutinoside, quercetin‐3‐O‐glucoside, kaempferol‐3‐O‐glucoside, luteolin were detected in different amounts. Strongest antioxidant capacities were observed with C. creticus, and C. parvifolius (0.476 and 0.452, respectively). Minimum inhibitory concentrations (MIC) of the extracts were determined between 32 and 128 μg/mL against different bacteria and Candida strains. C. monspeliensis and C. laurifolius extracts were inhibited the biofilm production levels of three Gram‐negative bacteria (E. coli, S. enterica, P. aeruginosa), two Gram‐positive bacteria (S. aureus, B. subtilis) and three Candida strains (C. albicans, C. parapsilosis, C. krusei). C. creticus extract showed strongest cytotoxic activity against human breast adenocarcinoma (MCF‐7) and prostate cell lines (PC‐3) (IC50: 14.04±2.78 μg/mL and 34.04±2.74 μg/mL, respectively) among all plants tested.

Psychological stress exerts its effects mainly through the release of corticotropin releasing hormone (CRH), which activates inflammatory pathways in skin (inter alia), resulting in redness, extracellular matrix degradation, loss of skin elasticity and firmness, and the appearance of wrinkles—namely, accelerated skin aging. In order to propose a solution to this neurogenic aging phenomenon, we report here on studies using a myricitrin-rich extract of Cistus incanus, a Mediterranean shrub used in traditional medicine for the treatment of inflammatory and other diseases. These studies include a CRH receptor (CRH-R1) blocking assay; in vitro inflammatory cytokine reduction under CRH stimulation, and ex vivo NF-kB inhibition; and a double-blind clinical trial performed on highly stressed panelists, evaluating skin inflammation and wrinkling (active formulation vs. placebo control, applied split-face following a computer-generated randomization scheme; 36 subjects recruited and randomized, 30 analyzed; no adverse effects recorded; EMA/INFARMED registration #118505, internally funded). The results show that this extract can effectively block the CRH-R1 receptor, preventing NF-κB activation and the production of related pro-inflammatory cytokines. In a clinical setting, this same extract delivered significant anti-inflammatory and anti-aging effects. Taken together, these results demonstrate the value of this extract as a cosmetic active to counter neurogenic inflammation and skin aging.
