Abstract

Kaempferia parviflora Wall. ex Baker, Zingiberaeceae has been used in traditional medicine in Vietnam for the treatment of inflammation, abdominal pain, indigestion, menstrual cramps, fatigue. From the n-hexane fraction of the rhizomes of Kaempferia parviflora, six compounds were isolated and determined as 5-hydroxy-3,7-dimethoxyflavone (1), 5,7-dimethoxy chrysin (2), 5-hydroxy-7-methoxyflavone (3), 5-hydroxy-3,4',7-trimethoxyflavone (4), 4',5,7-trimethoxyflavone (5), and 3,4',5,7-tetramethoxyflavone (6). The structures of 1-6 were elucidated by extensive spectroscopic methods (MS, 1D, and 2D NMR)

Keywords: Kaempferia parviflora, Zingiberaceae, flavonoid, black ginger
