對(duì)細(xì)辛道地藥材及其生境土壤中的微量元素含量進(jìn)行了比較研究。結(jié)果顯示,細(xì)辛道地藥材中 V、L i、Sn等元素的含量較高,Zn/ Cu比值較低,細(xì)辛對(duì) Ti、L i、B等元素有較強(qiáng)的富集作用 ;細(xì)辛的藥理活性與細(xì)辛道地藥材的微量元素含量特征有一定的相關(guān)性 ;種質(zhì)是影響細(xì)辛道地藥材中微量元素含量的主要因素,從微量元素的角度來(lái)看,細(xì)辛道地藥材的形成模式是以種質(zhì)為主導(dǎo)的多因子關(guān)聯(lián)決定型

Trace elements presented in the geo-herbal Asarum L.were studied with reference to the soil of its habitat.The results showed that the herb was rich in vanadium (V) and lithium (Li) and tin (Sn),but low in zinc (Zn) and copper (Cu),and had a strong tendency to accumulate titanium (Ti),lithium (Li) and boron (B).The pharmacological effects of geo-herbal Asarum L.seemed to be closely related with its characteristic contents of trace elements which were mainly affected by the idioplasm and various other minor factors.
