Kaltenhauser Margarethe, Ellmerer Ernst P., Zidorn Christian
A methanolic extract of Celtis australis leaves yielded 2’’-α- rhamnopyranosylvitexin and 2’’-α-rhamnopyranosyl-7-O-methylvitexin. Both compounds are known from other sources from earlier investigations but the full NMR data for the latter compound are reported for the first time.
