Abstract

Seven sucrose esters, physakengoses K-Q (1-7) were isolated from the aerial parts of Physalis alkekengi var. franchetii. Their structures were elucidated on the basis of extensive spectroscopic analyses and chemical methods. These new compounds were tested for their antimicrobial abilities against Staphylococcus aureus, Bacillus subtilis, Pseudomonas aeruginosa and Escherichia coli. Among the isolated sucrose esters, compounds 1-5 showed potent antibacterial activity with MIC values ranging from 2.16 to 12.76 μg/mL.

Keywords: Antibacterial activity; Physalis alkekengi var. franchetii; Solanaceae; Sucrose ester.
