Abstract

Solanum torvum Swart, belonging to the family Solanaceae, a herb known as “Ca dai hoa trang”, “Ca hoang gai”, “Ca nong”, or “Ca du” in Vietnam, is widely distributed in Vietnam. Solanum torvum has been used as folk medicine to treat various illnesses, such as stomachache, cough, fever, toothache, and bee stings. As a part of our research on genus Solanum in Vietnam, three natural compounds including paniculonin A (1), paniculonin B (2), and isorhamnetin-3-O-glucopyranoside (3) were isolated from the water layer of Solanum torvum collected in Thua Thien - Hue. This is the first time compound 3 was isolated from this species.
