“…Nevertheless, Keskes et al 14 reported the methanol extract to show a stronger ability to scavenge DPPH radicals (EC 50 value = 2 μg mL −1 ). Taviano et al 35 studied the antioxidant activity of methanol and water extracts of five different Turkish Juniperus species, which showed a weaker activity in comparison with the herein studied extracts. On the other hand, the C. cinerea infusion extract demonstrated a higher DPPH radical scavenging activity (EC 50 = 24.8 ± 0.2 µg mL −1 ) in comparison with its hydroethanolic extract (EC 50 = 26.0 ± 0.1 µg mL −1 ), contrary to what happened for all the remaining methods for both species.…”

The aim of this study was to characterize the individual phenolic profile and antioxidant, anti-inflammatory, cytotoxic, and antimicrobial activities of hydroethanolic and infusion extracts prepared from Algerian Saharan Juniperus phoenicea L. and Cotula cinerea (Del). The phenolic profile was determined using a liquid chromatograph coupled to a diode array detector and an electrospray ionization mass spectrometer (LC-DAD-ESI/MS). A total of thirteen and nine individual phenolic compounds were identified in J. phoenicea and C. cinerea, respectively. 3-p-Coumaroylquinic acid, quercetin- and myricetin-O-pentoside were the major compounds present in J. phoenicea; on the other hand, C. cinerea presented luteolin-7-O-glucoside, luteolin-O-malonylhexoside, and 5-O-caffeoylquinic acid as the main molecules. In general, all samples exhibited interesting antioxidant activity when compared to the standard Trolox, but J. phoenicea extracts presented the highest bioactivity. Likewise, all the samples exhibited anti-inflammatory activity; thus J. phoenicea hydroethanolic extracts showed the highest potential (88 ± 8 μg mL-1). In addition, their cytotoxicity was evaluated towards a panel of four selected cell lines (HeLa, NCI-H460, MCF-7 and HepG2), and all the extracts showed cytotoxic effects, with J. phoenicea extracts being the most effective. The in vitro antimicrobial activity of the plant extracts was moderate, Gram-positive bacteria thus being more sensitive than the Gram-negative strains (MIC values between 5 and 20 mg mL-1). The present work suggests that J. phoenicea and C. cinerea are sources of bioactive ingredients with potential use in the food and pharmaceutical industries.

Chemical characterization of three Juniperus species: J. foetidisima (JF), J. excelsa (JE) and J. communis (JC) from Macedonian flora enclosed determination of yield and essential oil composition of the oils obtained by hydro-distillation of dried leaves and determination of the content of total phenols and total flavonoids in dried plant material. GC/FID/MS analysis showed mainly monoterpene profile of the JC oil and combined monoterpene/sesquiterpene profile of JF and JE oils. Sesquiterpene cedrol was found as an important constituent of the JF and JE, thus the JF oil was characterized by three main components (a-pinene, limonene and cedrol, in amount up to 67.63%, 27.11% and 33.91%, respectively) and JE oil by four components (a-pinene, sabinene, cis-thujone and cedrol, in amount up to 33.83%, 29.49%, 26.20% and 24.44%, respectively). The JC oil was free of cedrol, but contained relatively large sesquiterpene fraction (sesquiterpene hydrocarbons and oxygen containing sesquiterpenes in amounts up to 28.64% and 13.57%, respectively). The JC oil was characterized by three monoterpene components (a-pinene, sabinene and terpinen-4-ol, presented up to 28.68%, 16.27% and 12.16%, respectively). The content of total phenols determined by Folin-Ciocalteu method ranged from 96.18-122.91 mg GAE/g dw (water extraction) while the content of total flavonoids ranged from 2.05-11.91 mg CE/g dw (ethanol extraction). Both water and ethanol extracts possessed radical scavenging activity against DPPH radical. Water extracts were more powerful with % of inhibition of DPPH ranging up to 64.52%, 67.40% and 78.23% for water extract (10 mg/ml) of JF, JE and JC, respectively. Obtained results showed correlation with the content of total phenols.

“…For example, Pinus nigra (tar, resin, and gum) exhibited strong antimicrobial [55], wound healing [56], and antiparasitic [57] activity properties. Allium sativum was found to have antibacterial [31] and antiparasitic [32][33][34] effects. Rhus coriaria was found to have potent antibacterial [35] and antioxidant properties [36].…”

Aim: The aims of the present study are to determine the significant plant species utilized in ethnoveterinary medicine of Central Anatolia region (Turkey), identify methods used for different veterinary preparations, and to compare the plants used in the treatment of different animal dermatological diseases in other regions of Turkey and different parts of the world. Methods: Interviews were conducted with 173 individuals in total by means of a semi-structured questionnaire, between 2009 and 2013, for the purpose of recording traditional veterinary remedies and practices employed in animal health care. In order to evaluate the reliability and richness of the knowledge of medicinal plants in the area, quantitative indices, such as "informant consensus factor (FIC)," "use value (UV)," "relative frequency citation," and "fidelity level," were used for the data analysis. Results: The findings of this study have revealed about 26 species, including herbs, trees, and green algae belonging to 22 botanical families utilized in the treatment of veterinary dermatological diseases by breeders in Central Anatolia. In the present study, the highest FIC score (0.90) was identified for cracked nipples. It was determined that Pine tar and Cydonia oblonga were used for the above-mentioned purpose. The second highest FIC value (0.87) was identified for ringworm. A number of medicinal plants were very popular and utilized intensively in the present research area. In accordance with the calculation performed on the basis of the UV, it was determined that Pinus nigra (0.43) and Allium sativum (0.28) had the highest UVs. Conclusion: The current study has emphasized the ethnoveterinary knowledge of plants recently in use and their new usage in the Central Anatolia region of Turkey.
