Rhamnopyranosylvitexin derivatives from Celtis australis

A methanolic extract of Celtis australis leaves yielded 2''-α-rhamno- pyranosylvitexin and 2''-α-rhamnopyranosyl-7-O-methylvitexin. Both com- pounds are known from other sources from earlier investigations but the full NMR data for the latter compound are reported for the first time.
