【摘要】 风干的黄姜花（Hedychium flavum）根茎粉碎后，用工业甲醇浸泡提取。提取物水溶后用乙酸乙酯萃取，乙酸乙酯萃取部分利用柱层析和HPLC等方法进行分离，经NMR等方法鉴定后，得到4个二芳基庚烷类化合物，化合物分别为：1,7-bis(4-hydroxy-3-methoxyphenyl)heptane-3,5-diol (1)、5-hydroxy-1-(4’-hydroxyphenyl)-7-(4’’-hydroxy-3’’-methoxyphenyl)-3-heptanone (2)、gingerenone A (3)和coriandralpinin C (4)，均为首次从黄姜花中分离得到。更多还原

【Abstract】 The rhizomes of dried Hedychium flavum were crushed, extracted with industrial methanol. The extract was dissolved with water and then extracted with ethyl acetate. The ethyl acetate part was separated by gel column chromatography and HPLC. Four diarylheptanes were obtained and identified by NMR, and the compounds were identified as 1,7-bis(4-hydroxy-3-methoxyphenyl)heptane-3,5-diol(1), 5-hydroxy-1-(4’-hydroxyphenyl)-7-(4’’-hydroxy-3’’-methoxyphenyl)-3-heptanone(2), gingerenone A(3) and coriandralpinin C(4). All the compounds were isolated for the first time from Hedychium flavum.更多还原
