摘　　要：从大花红景天(Rhodiola crenulata)根中分离出六个成分(Ⅰ～Ⅳ)。应用与已知品对照理化常数和光谱数据,鉴定Ⅰ,Ⅱ,Ⅲ,Ⅳ和Ⅴ分别为红景天苷(salidroside Ⅰ)、酪醇(p-tyrosolⅡ)、焦棓酸、没食子酸和β-谷甾醇。Ⅵ(大花红天素crenulatin)为一新的△~1-异戊烯-3-氧-β-D-葡萄糖苷(△~1-isopentenyl-3-O-β-D-glucopyranoside),由光谱法证明其结构为Ⅵ。Six chemical components I～IV were isolated from the roots of Rhodiolacrenulata (Crassulaceae). Five ( I ～V ) of them were identified as known salidroside(I),p- tyrosol(II),pyrogallol, gallic acid, and β- sitosterol, based on comparison of itsRf(TLC), mmp and spectral data with those of authentic samples. The sixth componentwas found to be a new Δ~1- isopentenyl- 3 - O - β- D- glucopyranoside and namedcrenulatin(VI). Its structure was confirmed on the basis of its spectral data(IR, MS,~1H- and ^(13)C- NMR).
