从胡桃楸(Juglans mandshurica)的新鲜果实中分离得到5个新的α-四氢萘酮糖苷。胡桃楸新鲜果实(5kg)用水(10L)煎煮6h,过滤,滤液依次用同体积的己烷、乙酸乙酯和正丁醇提取。正丁醇提取物(50g)上Diaion HP-20柱(60cm×11cm),用水、40%甲醇、80%甲醇和甲醇洗脱。40%甲醇部分蒸干( Five new alpha-tetralone glycosides were isolated from the fresh fruit of Juglans mandshurica. The fresh fruit (5 kg) of Juglans mantshuensis was decocted with water (10 L) for 6 h, filtered, and the filtrate was successively extracted with the same volume of hexane, ethyl acetate and n-butanol. The n-butanol extract (50 g) was applied to a Diaion HP-20 column (60 cm x 11 cm) eluted with water, 40% methanol, 80% methanol and methanol. 40% methanol was partially evaporated (
