Abstract:

A new glucoside, fastigitin A (1), namely 2-O-β-D-glucopyransyl-3-methyl methyl pinalate,together with twelve known constituents (2－13), was isolated from the root of Rhodiola fastigiata (Hook. f. et Thoms.) S. H. Fu collected from Nujiang Lisu autonomous region, Yunnan, China. Their structures were identified by spectral (including 2D-NMR techniques) and chemical methods. Compounds 2 and 5-9 were obtained from this plant for the first time.

摘要：从云南怒江产的长鞭红景天(Rhodiola fastigiata (Hook. f. et Thoms.) S. H. Fu)根茎中分离得到13个化合物,它们的结构通过波谱和化学方法得到鉴定.其中,化合物1被鉴定为新的葡萄糖甙(2-O-β-D-吡喃葡糖基-3-甲基-戊酸甲酯),命名为长鞭红景天素甲,化合物2和 5～9首次从该植物中分离得到.
