Abstract

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.
