Abstract

From an extract of root bark of Olinia usambarensis, which showed antifeedant activity, 5-(4′-O-β-d- glucopyranosyl)-caffeoyloxy-5,6-dihydro-4-methyl-(2H)-pyran-2-one, named olinioside, caffeic acid, and 4-O-β-D- glueopyranosylcaffeic acid were isolated. The structure of orinioside was assigned by chemical and spectroscopic methods. © 1993.
