Icariside B5 is one of the widely distributed megastigmane glucosides among plant sources. The absolute structure of icariside B5 was reinvestigated by chemical conversion from the related compound and the application of the modified Mosher's method. As a result, the structure of icariside B5 was revised to be (6S,9S)-6,9-dihydroxymegastigman-4-en-3-one 9-O-β-D-glucopyranoside.
淫羊藿苷 B5 是植物来源中广泛分布的巨黄酮苷之一。通过对相关化合物进行化学转化,并应用改进的莫舍尔法,重新研究了淫羊藿苷 B5 的绝对结构。结果,冰片苷 B5 的结构被修正为 (6S,9S)-6,9-二羟基巨天麻素-4-烯-3-酮 9-O-β-<小>D小>-吡喃葡萄糖苷。
