目的: 研究萱草Hemerocallis fulva根的化学成分。方法: 用色谱方法进行分离纯化萱草根的氯仿和正丁醇提取物, 根据化合物的理化性质和光谱数据进行结构鉴定。结果: 从萱草根的氯仿和正丁醇提取物中分离鉴定了10个化合物: 蒺藜嗪(terresoxazine,Ⅰ)、11-氧代-β-乳香酸(Ⅱ)、何伯烷-6α,22-二醇(Ⅲ)、海可皂苷元(Ⅳ)、谷甾-4-烯-3β-醇(Ⅴ)、谷甾-4-烯-3-酮(Ⅵ)、ω-阿魏酰氧酸(ω-feruloyloxy acid,Ⅶ)、3, 4-二羟基反式肉桂酸(Ⅷ)、对甲基反式肉桂酸(Ⅸ)、香草酸(Ⅹ)。结论: 化合物Ⅰ～Ⅳ、Ⅶ为首次从该属植物中分得。

Objective To study the chemical constituents in the roots of Hemerocallis fulva．Methods：Compounds were isolated from the CHCl3 and iv/-butanol fraction of the etoh extract by repeated column chromatography and their structures were identified by spectral analysis and physicochemical properties．Results： From the CHCl3 and butanol fraction of the etoh extract in the roots of H．fulva, ten compounds were isolated and identified as terresoxazine(I), 11-keto-pboswellic acid(I), hopane-6a,22-diol(I), hecogenin(Ⅳ), stigmast-4-en-3t3-ol(V), stigmast-4-en-3-one(Ⅵ), a'-feruloyloxy acid (I/!), (E)-3，4-dihydroxyl cinnamic acid(Ⅶ), (E)-P-methyl cinnamic acid(Ⅸ), and vanillic acid(X)． Conclusion Compounds I-IV and Vi are isolated and identified from the plants of merocallis L．for the first time．
