Physaloside A, an acylated sucrose ester from Physalis viscosa.
Chemical investigations of the crude MeOH extract of Physalis viscosa led to the identification of the novel acylated sucrose ester physaloside A (1). The structure of 1 was determined by 2D NMR analysis, and the absolute configuration was determined by chemical degradation and comparison with authentic standards.
