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。
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),9,16-dioxo-10,12,14-octadeca-trienoic acid(4),tithoniamide B(5),corchoionol C (6),daucosterol (7),2,3,5,4'-tetrahydtoxysilbene-2-O-β-D-glucopyranoside (8). Conclusion: Compound 3 was isolated from the genus Gnaphalium for the first time and compounds 1, 2, 4-6, 8 were isolated from the family Compositae for the first time.
