北细辛不同生长期甲基丁香酚和黄樟醚的气相色谱法定量分析

对北细辛不同生长期所含甲基丁香酚（ｍｅｔｈｙｌｅｕｇｅｎｏｌ）和黄樟醚（ｓａｆｒｏｌｅ）用气相色谱法进行了定量分析。结果表明：地下部分甲基丁香酚以萌动期和果后期含量为最高；黄樟醚以萌动期、花期和果后期为最高。地上部分二者均以花期为最高，以后各时期依次减少。

Analysis of Season Variation of Methyleugenol and Safrole in Asarum Heterotropoides by Gas Chromatography

We established a method for quantitative analysis of methyleugenol and safrole in Asarum hete rotropoides by GC to study their season variation. The results showed that the content of methyleugenol in the essential oil of the subterranean part of different seasons was 21% 39%, and that for safrole was 17% 33%. In the upterranean part, methyleugenol was 1 4% 9 6%, and safrole was 0 36% 2 1%. It is clear that methyleugenol and safrole are provided mainly by the subterranean part. The quantity of methyleugenol is the richest in the period of sprouting and after fruiting, and for the safrole content the richest periods are that of sprouting, blooming and after fruiting.In the case of upterranean part, the richest time is blooming period both for methyleugenol and safrole, and after blooming they decrease gradually.
