Abstract: Chemical constituents of Alpinia sichuanensi were studied.Eight compounds were isolated and purified by Silic Gel and Sephadex LH-20 column chromatography. Their structures were elucidated by chemical and spectroscopic methods as 3, 5-dihydroxy-4',7-dimethoxyflavone(1), 4',7-dihydroxy-5-methoxyflavanone(2), 4',5,7-trihydroxyflavone(3), 5,7-dihydroxy-4'-methoxyflavone (4), p-coumaric acid(5), β-daucosterol(6), β-sitosterol(7), stigmasterol(8).Compounds 1-5 are isolated from this plant for the first time.

Key words: Alpinia sichuanensis, Zingiberaceae, chemical constituents
