不同种源五味子油化学组分的差异性分析

Difference Analysis on Chemical Composition of Schisandra Fruit Oil of Different Provenances

为了探究不同种源五味子油化学组分及相对含量的差异性,以9个种源的五味子为试材,采用索氏提取法萃取五味子油,用气-质联用法检测。结果表明:1)从9个种源五味子油中共分离得到217个成分,其中共有成分14种,占总油量的78.05%。2)对9个种源五味子油进行聚类分析,可聚为2大类:第1类有安康、栾川、山西、西峡4个种源;第2类有凤城、韩国、宽甸、黑龙江、抚顺5个种源,其中山西种源与栾川种源之间遗传距离最小,化合物种类及相对含量相似度较高。

In order to explore the difference of chemical constituents and relative contents of Schisandra fruit oil of different provenances, this study took schisandra fruit of 9 provenances as material to extract schisandra fruit oil by Soxhlet extraction method, and the obtained schisandra fruit oil were analyzed by GC/MS. The results showed that ：1）217 components were separated from schisandra fruit oil of 9 provenances, including 14 common constituents which constituted 66.97% of the total oil. 2）With the methods of hierarchical cluster analysis, Schisandra fruit of 9 provenances could be clustered into two categories. The first category included 4 provenances： Ankang, Luanchuan, Shanxi and Xixia; the second category included 5 provenances： Fengcheng, South Korea, Kuandian, Heilongjiang and Fushun. The genetic distances between Shanxi and Luanchuan provenance was smallest, and the similarity degree of compounds and relative contents was relatively high.
