Twelve new dammarane-type glycosides ( 1- 12) were isolated from the ethanol extract from the roots of a wild-type of Gynostemma pentaphyllum. The structures of the compounds were elucidated by 1D and 2D NMR spectroscopic analysis as well as by chemical degradation. The compounds contained six structurally diverse aglycons similar to those of the reported ginseng saponins with differences in the oligosaccharide moieties.
从野生绞股蓝根的乙醇提取物中分离得到 12 种新达玛烷型糖苷（1-12）。通过 1D 和 2D NMR 光谱分析以及化学降解阐明了这些化合物的结构。这些化合物含有 6 种结构不同的苷元，与已报道的人参皂苷相似，只是寡糖部分有所不同。
