摘      要：Objective To study the chemical constituents in the stems and leaves of Alpinia oxyphylla *** The chemical constituents were isolated by using various column chromatorgaphies and their structures were elucidated on basis of physicochemical constants and spectral data *** Nine compounds were obtained and determined to be p-hydroxycinnamic acid(1),3,4-dihydroxybenzamide(2),β-sitosterol(3),tectochrysin(4), chrysin(5),izalpinin(6),pinocembrin(7).pinostrobin(8) and myristic acid(9).Conclusion: Compounds 1,2,7 and 8 were obtained from this genus for the first time.
