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.
