目的：研究太白米Ｎｏｔｈｏｌｉｒｉｏｎｂｕｌｂｕｌｉｆｅｒｕｍ（Ｌｉｎｇｅｌｉｓｈ．）Ｓｔｅａｒｎ干燥小鳞茎的化学成分。方法：采用硅胶柱色谱分离化学成分，ＩＲ，１ＨＮＭＲ，１３ＣＮＭＲ，ＭＳ等方法进行结构鉴定。结果：从正丁醇萃取物中分离鉴定了６个酚酸类成分，分别为对香豆酸甲酯（ｍｅｔｈｙｌｐｃｏｕｍａｒａｔｅ，Ｉ）、对甲氧基肉桂酸（ｐｍｅｔｈｏｘｙｃｉｎｎａｍｉｃａｃｉｄ，Ｉ）、对香豆酸（ｐｃｏｕｍａｒｉｃａｃｉｄ，ＩＩ）、阿魏酸（ｆｅｒｕｌｉｃａｃｉｄ，ＩＶ）、咖啡酸乙酯（ｅｔｈｙｌｃａｆｅａｔｅ，Ｖ）、１Ｏ咖啡酰甘油酯（１Ｏｃａｆｅｏｙｌｇｌｙｃｅｒｏｌ，ＶＩ）；另外，从其石油醚萃取物和氯仿萃取物中分离鉴定了β谷甾醇（ＶＩＩ）、β谷甾醇葡萄糖苷（ＩＸ）和正二十八酸（ＶＩＩ）。结论：化合物ＶＩ为新化合物，其它化合物均为首次从本植物中分离得到
OBJECTIVE: To study the chemical constituents of Stebul’s dried bulbs of Notholirion bulbulliferum (Lingelish.). METHODS: The chemical constituents were isolated by silica gel column chromatography and identified by IR, 1H NMR, 13C NMR and MS. Results: Six phenolic acids were isolated and identified from n-butanol extracts. They were methyl p-coumarate (I), p-methoxycinnamic acid (I), and p-methoxycinnamic acid (I). P-coumaric acid (II), ferulic acid (IV), ethyl caffeate (V), 1-O-cafeoylglycerol (VI); Beta-sitosterol (VII), β-sitosterol glucoside (IX) and n-dodecanoic acid (VII) were isolated from their petroleum ether extracts and chloroform extracts. Conclusion: Compound VI is a new compound. Other compounds were isolated from this plant for the first time.
