摘要

目的：研究鼠曲草中乙酸乙酯部位的化学成分。方法：采用硅胶柱色谱、Sephadex LH-20等分离手段结合对鼠曲草乙酸乙酯萃取部位的E1~E3进行分离纯化，通过波谱数据分析（1H-NMR，13C-NMR）进行结构鉴定。结果：从乙酸乙酯萃取部位的Fr1~Fr3分离了8个化合物，分别鉴定为正三十四烷醇（1）、paoriscabratine（2）、单棕榈酸酯（3）、9，16-二羰基-10，12，14-三烯-十八碳酸（4）、tithoniamide B（5）、corchoionol C（6）、胡萝卜苷（7）、2，3，5，4-四羟基反式二苯乙烯-2-O-β-D-吡喃葡萄糖苷（8）。结论：化合物 3 为首次从鼠曲草属植物中分离到，化合物 1，2，4~6，8 为首次从菊科植物中分离到。

Abstract

Objective: To study chemical constituents of Gnaphalium affine. Method: The ethyl acetate extract part was separated and purified by silica gel column chromatography and Sephadex LH-20.The compounds isolated chemical structures were identified by their spectral data (1H-NMR

13C-NMR). Result: Nine compounds were isolated from the ethyl acetate extract portion. They were identified as n-tetratriacontanol (1)

paoriscabratine (2)

glyceryl monopalmitate (3)

16-dioxo-10

14-octadeca-trienoic acid(4)

tithoniamide B(5)

corchoionol C (6)

daucosterol (7)

4'-tetrahydtoxysilbene-2-O-β-D-glucopyranoside (8). Conclusion: Compound 3 was isolated from the genus Gnaphalium for the first time and compounds 1

4-6

8 were isolated from the family Compositae for the first time.
