Six substances were isolated from the branches and leaves of the Chinese herb Leptopus Chinensis (Bunge) Pojark. by column chromatography for the first time. Their structures were elucidated as 3α-hydroxyfriedelan-2-one, saccharose, triacontanol, friedelane-2α,3β-diols, β-sitosterol-3-O-β-D-glucoside, and β -sitosterol on the basis of x-ray, chemical, and spectroscopic methods.
通过柱层析法,首次从中草药莱菔子(Bunge)的枝叶中分离出六种物质。根据 X 射线、化学和光谱方法,阐明了它们的结构为 3α-羟基油菜素-2-酮、糖醛酸、三芳醇、油菜素-2α,3β-二醇、β-谷甾醇-3-O-β-D-葡萄糖苷和 β -谷甾醇。
