Abstract

Salvia leriifolia is an endemic to Iran belongs to Lamiaceae. This plant has numerous valuable properties, including analgesics, anti-inflammatories, sedatives, antioxidants and has significant applications in the medical, pharmaceutical and food industries. The purpose of this study was to evaluate the chemical composition and antioxidant activity of essential oils roots S. leriifolia collected from six natural habitats in the northeast of Iran. Analysis of essential oils was performed by GC/FID and GC/MS techniques. Torbat-e Heydarieh (0.06 % w/w) had the highest and Baghjar (0.02 % w/w) had the lowest oil content. It was found that the essential oils were rich in diterpenes such as abietatriene (32.5-39.4 %), labda-7,13-dien-15-ol acetate (23.2-30.8%) and ferruginol (7.9-12.0 %). The essential oils were assessed for radical scavenging activity using the DPPH assay. The most active sample was the essential oil from Torbat-e Heydarieh with an IC₅₀ value of 0.15 ± 0.09 mg/ml.

摘要

丹参为伊朗的特有种，属于唇形科。该植物具有许多有价值的特性，包括止痛药，消炎药，镇静剂，抗氧化剂，并且在医疗，制药和食品工业中具有重要的应用。这项研究的目的是评估香精油根S的化学成分和抗氧化活性。紫草收集自伊朗东北部的六个自然栖息地。精油的分析是通过GC / FID和GC / MS技术进行的。Torbat-e Heydarieh（0.06％w / w）的油含量最高，而Baghjar（0.02％w / w）的油含量最低。发现该精油富含二萜，例如己二三烯（32.5-39.4％），labda-7，13-二烯-15-醇乙酸酯（23.2-30.8％）和铁氨酚（7.9-12.0％）。使用DPPH分析评估香精油的自由基清除活性。活性最高的样品是Torbat-e Heydarieh的香精油，IC ₅₀值为0.15±0.09 mg / ml。
