N2 - Chemical analysis of the stem bark of Cylicodiscus gabunensis (Mimosaceae) yielded, in addition to the known eryhrodiol (4) and sojagol (IV) (5), three new glycosides designated coumestoside A (1), coumestoside B (2) and erythrodiside A (3). Their structures were established by chemical and spectroscopic means as 9-O-β-D-glucopyranosyl-4-hydroxycoumestrol, 9-O-β-L-rhamnopyranosyl-4- hydroxycoumestrol and 3-O-α-L-rhamnopyranosylerythrodiol-28-O-β-D- galactopyranoside, respectively.
