Abstract Salvia is the largest genus of the Lamiaceae family, representing approximately 1000 species and possessing a high rate of endemism all over the world. S. candidissima Vahl. ssp. occidentalis is a herbaceous perennial native throughout Turkey. This study aimed to estimate the phytochemical composition of S. candidissima Vahl. ssp. occidentalis. The main constituents were sclareol (35.24 %), spathulenol (7.98 %), and caryophyllene oxide (6.64 %), among the detected 45 constituents representing 97.65 % of the total essential oil content. Total phenolic content and antioxidant activity were determined in the 70 % and 95 % ethanol extracts of the plant. The total phenolic content was higher in 95 % ethanol extract (25.16 mg equivalent of gallic acid per g dry weight (dw)). The antioxidant activity of the ethanol extracts was determined using four antioxidant assays, including methods based on radical scavenging activity and methal reducing capacity, respectively (DPPH, ABTS, FRAP and CUPRAC assays). Among the samples, 70 % ethanol extract exhibited the highest CUPRAC activity (670.39 mM TE/g dw) followed by DPPH radical scavenging activity of 95 % ethanol extract (275.67 mM TE/g dw).

Salvia candidissima Vahl 的植物化学成分。ssp。来自土耳其的 occidentalis

摘要 鼠尾草是唇形科最大的属，约有 1000 种，在世界范围内具有很高的特有率。S. candidissima Vahl。ssp。occidentalis 是一种遍及土耳其的多年生草本植物。本研究旨在估计 S. candidissima Vahl 的植物化学成分。ssp。西方人。检测到的45种成分占精油总含量的97.65%，主要成分为香紫苏醇（35.24%）、匙羹藤醇（7.98%）和石竹烯氧化物（6.64%）。在植物的 70% 和 95% 乙醇提取物中测定总酚含量和抗氧化活性。95% 乙醇提取物中的总酚含量更高（每克干重 (dw) 相当于 25.16 mg 没食子酸）。乙醇提取物的抗氧化活性使用四种抗氧化试验测定，包括分别基于自由基清除活性和金属还原能力的方法（DPPH、ABTS、FRAP 和 CUPRAC 试验）。在这些样品中，70% 乙醇提取物表现出最高的 CUPRAC 活性（670.39 mM TE/g dw），其次是 95% 乙醇提取物的 DPPH 自由基清除活性（275.67 mM TE/g dw）。
