Popis:	Two new coumestan glycosides, coumestoside C (1) and coumestoside D (2), were isolated from the stem bark of Cylicodiscus gabunensis Harms. Their structures were established by spectroscopic means and chemical transformations as 9- O-α-L-rhamnopyranosyl-3-hydroxy-4-(5′-hydroxy-3′-methylbut-2′ E-enyl) coumestan (1) and 9- O-β-D-galactopyranosyl-3- O- prenyl-4-hydroxycoumestan. Coumestoside C exhibited antimicrobial activity against Proteus vulgaris.
