秦芄挥发性成分研究

Chemical Compositions of the Essential Oil of Radix Gentianae Macrophyllae

目的:研究秦芄(Radix Gentianae Macrophyllae)中的挥发性成分。方法:利用水蒸气蒸馏法提取秦芄挥发油,用GC/MS进行测定,结合计算机检索技术对分离的化合物进行结构鉴定,应用色谱峰面积归一化法计算各成分的相对百分含量。结果:分离出8个组分,鉴定出7个化学成分。检出率为91.40%。秦艽挥发性成分大于1%的分别确定为萜品烯-4-醇1.224%,(E,E)-2,4-癸二烯醛1.295%,棕榈酸乙酯32.009%,棕榈酸54.608%。结论:首次报道了用GC/MS对秦艽挥发性成分的研究,为该类植物的研究开发提供必要的试验数据。

Objective：To study the chemical compositions of essential oil from Radix Gentianae Macrophyllae. Methods：The oil was obtained by steam distillation. The chemical compositions were separated and identified by GC/MS. The relative percentage of the oil constituents was calculated from the GC peak areas. Results： Eight components were detected in the volatile constituents of Radix Gentianae Macrophyllae; of which seven compounds representing 91.40% of the oil were identified. The major constituents that were above 1% were terpinen - 4 - ol 1.224 %, （ E, E） - 2,4 - decadienal 1.295 %, ethyl palmitate 32.009 %, palmitic acid 54.608 %. Conclusion： For the first time, the composition of essential oils of Radix Gentianae Macrophyllae was reported.
