| 摘 要： | 大火草（Ａｎｅｍｏｎｅ ｔｏｍｅｎｔｏｓａａ（Ｍａｘｉｍ．）Ｐｅｉ）根状茎提取物的乙酸乙酯部分对粘虫（ＬｅｕｃａｎｉａｓｅｐａｒａｔａＷａｌｋｅｒ）有较好的非选择性拒食活性。从该部分分离得到１１个化合物，通过ＮＭＲ、ＭＳ等波谱分析确定它们的结构分别为４，５-二甲氧基-７-甲基香豆素（１）、４-甲氧基-５-甲基-６，７-二氧亚甲基香豆素（２）、４，７-二甲氧基-５-甲基香豆素（３）、齐墩果酸（４）、齐墩果酮酸（５）、齐墩果酸-３-Ｏ-β-Ｄ-吡喃木糖甙（６）、β-谷甾醇（７）、豆甾醇（８）、胡萝卜甙（９）、豆甾醇-３-Ｏ-β-Ｄ-吡喃葡萄糖甙（１０）和过氧化麦角甾醇（１１）。这些化学成分均为首次从该植物中分离得到，其中１和２为新化合物。

| Abstract: | The roots of Anemone tomentosa (Maxim. ) Pei (Ranunculaceae) have been used as traditional medicine for the treatment of dysentery, infantile malnutrition, carbuncles, etc. Ethyl acetate extract of the roots displaied stronger antifeedant activity against Leucania separata Walker. Eleven compounds were isolated by silica gel columm chromatography from the extract and their structures were identified as 4,5-dimethoxyl-7-methyl-coumarin (1 ), 4-methoxyl-5(methyl-6, 7 - methylenedioxy- coulnarin (2 ), 4, 7 - dimethoxyl- 5 - methylcotnnarin (3), oleanolic arid (4), oleanonic acid (5), 3--O-5-D-xylopyranosyl oleanolic acid (6), -sitosterol (7), stigmaSterol (8), daucosterol (9), 3 - O-5- D- glucopystigmasterol (10 ) and egrterol pemtide (11) respectively on the baSis of special evidence. Compounds 1 and 2 are new naed products. |
