Abstract
Phytochemical analysis of Solanum nigrum has resulted in the isolation of two novel disaccharides. Their structures were determined as ethyl beta-D-thevetopyranosyl-(1-->4)-beta-D-oleandropyranoside (1) and ethyl beta-d-thevetopyranosyl-(1-->4)-alpha-D-oleandropyranoside (2), respectively, by chemical and spectroscopic methods.
