综合运用各种色谱技术对蓼科植物何首乌的块根进行分离纯化,并通过理化常数、波谱数据和化学方法鉴定化合物的结构。从中分离得到1个化合物,鉴定其结构为(S)-2-(2’-羟丙基)-5-甲基-7-羟基色原酮-7-O-α-L-岩藻糖基(1→2)-β-D-葡萄糖苷(1),为一个新的色原酮糖苷类化合物。 The tuberous roots of Polygonum multiflorum were isolated and purified by various chromatographic techniques. The structures of the compounds were identified by physicochemical constants, spectral data and chemical methods. One of the compounds was isolated therefrom and its structure was identified as (S) -2- (2’-hydroxypropyl) -5-methyl-7-hydroxychromosan-7-O-α-L-fucosyl (1 → 2) -β-D-glucoside (1), a new chromone-based glycoside compound.
