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-α-L-rhamnopyranosyl-4-hydroxycoumestrol and 3- O-α-L-rhamnopyranosylerythrodiol-28- O-β-D-galactopyranoside, respectively.
