摘要
This study aimed to investigate the chemical constituents from the flowers of Dendrobium chrysanthum and determine its bioactive compounds. [Method] The compounds were extracted by 95% alcohol and isolated by column chromatography on silica gel and Sephadex LH-20. Their structures were identified by spectroscopic analysis （1H NMR, 13CNMR and ElMS）. [Result] Nine compounds were obtained and identified as stigmasterol , β-sitosterol , linoleic acid , stigmast-4-en-3-one , dibutyl phthalate , moscatilin , ergosterol , ergosterol peroxide and daucosterol . [Conclusion] Al compounds were isolated from its flowers for the first time.
[Objective] This study aimed to investigate the chemical constituents from the flowers of Dendrobium chrysanthum and determine its bioactive compounds.[Method] The compounds were extracted by 95% alcohol and isolated by column chromatography on silica gel and Sephadex LH-20. Their structures were identified by spectroscopic analysis(1H NMR,13 CNMR and EIMS). [Result] Nine compounds were obtained and identified as stigmasterol(1), β-sitosterol(2), linoleic acid(3),stigmast-4-en-3-one(4), dibutyl phthalate(5), moscatilin(6), ergosterol(7), ergosterol peroxide(8) and daucosterol(9). [Conclusion] All compounds were isolated from its flowers for the first time.
