在紫毛香茶菜（Ｉｓｏｄｏｎ ｅｎａｎｄｅｒｉａｎｕｓ）叶子的乙醇提取物中，首次分离得到２个７，２０－环氧－对映－贝壳杉烯型二萜ｌｏｎｇｉｋａｕｒｉｎ Ｄ和Ｆ，用红外光谱、紫外光谱、质谱和核磁共振谱等波谱方法，对它们的结构进行了鉴定。
In the ethanol extract of leaves of Isodon enanderianus, two 7,20-epoxy-enantiomer-kaurene-type diterpene longikaurin D and F were isolated for the first time. Their structures were characterized by IR, UV, Mass spectrometry and nuclear magnetic resonance spectroscopy and other spectroscopic methods, their structure was identified.
