The essential oil compound, fatty acid composition and the in vitro antioxidant activity of the root and aerial of Glycyrrhiza echinata L., a medicinal plant growing in Turkey, have been studied. The antioxidant capacity tests were designed to evaluate the antioxidant activities of methanol extracts. Total phenolic and flavonoid concentrations of each extract were also determined by using both Folin-Ciocalteu reagent and aluminum chloride. The aerial part was found to possess the highest total phenolic content (146.30 ± 4.58 mg GAE/g) and total antioxidant capacity (175.33 ± 3.98 mg AE/g). The essential oil from root and aerial parts was analyzed by gas chromatography mass spectroscopy (GC-MS) systems. The major components identified were n-hexadecanoic acid, hexahydro farnesyl acetone, α-caryophyllen, hexanal and phytol. In fatty acid profiles of plant, palmitic, stearic, oleic and linoleic acid were detected as the main components. The results of this study have shown that the extracts G. echinata are suitable as a natural antioxidant and food supplement source for pharmacological and food industries due to their beneficial chemical composition and antioxidant capacity.
对生长在土耳其的药用植物刺果甘草的根和地上部分的精油成分、脂肪酸组成及体外抗氧化活性进行了研究。抗氧化能力测试旨在评估甲醇提取物的抗氧化活性。还使用福林 - 西奥尔特试剂和氯化铝测定了每种提取物的总酚和黄酮浓度。发现地上部分具有最高的总酚含量（146.30±4.58毫克没食子酸当量/克）和总抗氧化能力（175.33±3.98毫克抗坏血酸当量/克）。通过气相色谱 - 质谱联用（GC - MS）系统分析了根和地上部分的精油。鉴定出的主要成分是正十六烷酸、六氢法呢基丙酮、α - 石竹烯、己醛和叶绿醇。在植物的脂肪酸谱中，检测到棕榈酸、硬脂酸、油酸和亚油酸为主要成分。本研究结果表明，由于刺果甘草提取物具有有益的化学成分和抗氧化能力，适合作为制药和食品工业的天然抗氧化剂和食品补充剂来源。
