Acetophenone Diglycosides from Erythroxylum cambodianum

Two new acetophenone diglycosides, erythroxylosides A and B, were isolated from the aerial portion of Erythroxylum cambodianum together with (+)-catechin, (-)-epicatechin, quercetin 3-O-rutinoside, (3S,5R,6R,7E,9S-megastigman-7-ene-3,5,6,9-tetrol 3-O-beta-D-glucopyranoside and citroside A. The structural elucidations were based on analyses of chemical and spectroscopic...
