从细辛属植物大叶马蹄香根Asarum maximum的乙醇提取物中分离出10个化合物, 经理化常数和光谱鉴定其结构, 分别为左旋芝麻脂素(1-sesamin, Ⅰ)、2, 4, 5-三甲氧基苯甲醛(2, 4, 5-trimethoxyl-benzaldehyde, Ⅱ)、1-[(2, 4, 5-三甲氧基)-苯基]-1-丙酮(1-[(2, 4, 5-trimethoxyl)]-pheny l-1-proponone, Ⅲ)、1-[(3, 4-二甲氧基)-苯基]-1-丙酮(1-[(3, 4-dimetho xyl)]-phenyl-1-proponone, Ⅳ)、β-谷甾醇(β-sitosterol, Ⅴ)、十八酸单甘油酯(glycerol monostearic acid, Ⅵ)、细辛脑(asarone, Ⅶ)、胡萝卜苷(daucosterol, Ⅷ)、马兜铃内酰胺(aristololactamⅠ, Ⅸ)、7-甲氧基-马兜铃内酰胺Ⅳ(7-methoxyl-a ristololactam Ⅳ, Ⅹ)

Ten compounds were isolated from the root of Asarum maximum Hemsl. Their structures were identified as l-sesamin (Ⅰ), 2， 4， 5-trimethoxybenzaldehyde (Ⅱ), 1-［(2，4，5-t rimethox y)ph enyl］-1-propanone (Ⅲ), 1-［(3，4-dimethoxy)phenyl］-1-propanone (Ⅳ), β-sitosterol (Ⅴ), glyceryl monostearate (Ⅵ), asarone (Ⅶ), daucosterol (Ⅷ ), aristololactam Ⅰ (Ⅸ) and 7-methoxyaristololactam Ⅳ (Ⅹ) on the basis o f physicochemical constants and spectral analysis (IR, MS, 1HNMR, 13CNMR). All compounds were obtained from this plant for the first time. Ⅱ， Ⅲ， Ⅳ， Ⅵ and Ⅸ were isolated for the first time from Asarum L,.
