从大花红景天中分离得到5个结晶,经光谱及理化性质鉴定为:草质素-7-O-α-L-鼠李糖甙(rhodionin,Ⅰ),草质素-7-O-(3“-β-D-葡萄糖基)-α-L-鼠李糖甙(rhodiosin,Ⅱ),酪醇(tyrosol,Ⅲ),红景天甙(salidroside,Ⅳ),没食子酸(gallicacid,Ⅴ)。
Five crystals were isolated from Rhodiola crenulata and identified by spectroscopic and physicochemical properties as follows: rheolin-7-O-α-L-rhodose 甙 (rhodionin, I), trehalose-7-O- (3”-β-D-glucosyl)-α-L-rhodiosin (II), tyrosol (III), salidroside (IV), gallicacid, V).
