title: Antimicrobial C-glucoside from aerial parts of Diospyros nigra.
abstract: A new C-alkylglucoside, diospyrodin [beta-1C-(1'S*,2'R*,3'R*,4'S*-1',2',3',4',5'-pentahydroxypentyl)-glucopyranoside] (1) has been isolated as its nonaacetate from the leaves and stems of Diospyros nigra. Its structure was elucidated on the basis of chemical and spectral properties and a single crystal X-ray analysis. It showed antimicrobial activity against Gram-positive and Gram-negative bacteria.
