草豆蔻的化学成分（英文）

目的：研究草豆蔻的化学成分。方法：采用硅胶和Sephadex LH-20柱色谱方法进行化合物的分离和纯化, 根据理化性质和光谱数据鉴定化合物结构。结果：从草豆蔻提取物中分离得到了10个化合物, 经鉴定分别为：1, 7-双苯-5-羟基-4, 6-庚烯-3-酮 （trans, trans-1, 7-diphenyl-5-hydroxy-4, 6-hepten-3-one, 1）, 乔松素 （pinocembrin, 2）, 山姜素 （alpinetin, 3）, 7, 4′-二羟基-5-甲氧基二氢黄酮 （4）, 蜡菊亭（helichrysetin, 5）, 2′, 4′-二羟基-6′-甲氧基二氢查尔酮 （uvangoletin, 6）, （1E, 4Z）-5-hydroxy-1-phenylhexa-1, 4-dien-3-one （7）, katsumadain B（8）, 羊踯躅素I（rhodomollein I, 9）和金色酰胺醇酯（aurantiamide acetate,10）。结论：化合物7为一个新天然产物, 化合物9和10为首次从该属中分离得到。

Chemical Constituents from the Seeds of Alpinia katsumadai Hayata

AIM： To investigate the chemical constituents from the seeds of Alpinia katsumadai Hayata. METHODS： Compounds were isolated and purified by column chromatography with silica gel and Sephadex LH-20, and their structures were identified on the basis of physiochemical properties and spectroscopic data. RESULTS： Ten compounds are isolated and elucidated as trans, trans-1, 7-diphenyl-5-hydroxy-4,6-hepten-3-one （1）, pinocembrin （2）, alpinetin （3）, 7, 4′-dihydroxy-5-methoxy flavanone （4）, helichrysetin （5）, uvangoletin （6）, （1E, 4Z）-5-hydroxy-1-phenyl-hexa-1, 4-dien-3-one （7）, katsumadain B （8）, rhodomollein I （9）, and aurantiamide acetate （10）. CONCLUSION： Compound 7 was a new natural product. Compounds 9 and 10 were isolated from the genus for the first time.
