The composition and in vitro antioxidant activities of the essential oil and methanol extract of the aerial parts of Viola tianshanica were evaluated in this research. GC-MS analysis of the essential oil resulted in the identification of 15 constituents, representing 89.67% of the oil. The major compounds detected in the essential oil were dibutyl phthalate (15.19%), hexadecanoate methyl (8.65%), n-hexadecanoic acid (3.07%) and 2,3-pentanedione (2.62%). Essential oil and methanol extract were tested for their antioxidant activities using 1,1-diphenyl-2-picryl-hydrazyl free radical scavenging and β-carotene linoleic acid assay. In addition, the total phenol of essential oil, polar subfraction and non-polar subfraction were determined.
本研究评价了天山堇菜地上部分精油和甲醇提取物的组成及其体外抗氧化活性。对精油进行 GC-MS 分析，鉴定出 15 种成分，占油的 89.67%。精油中检测到的主要化合物为邻苯二甲酸二丁酯（15.19%）、十六烷酸甲酯（8.65%）、正十六烷酸（3.07%）和 2,3-戊二酮（2.62%）。使用 1,1-二苯基-2-苦基肼自由基清除和β-胡萝卜素亚油酸测定法，测试了精油和甲醇提取物的抗氧化活性。此外，还测定了精油、极性亚组分和非极性亚组分的总酚含量。
