摘要 目的:研究桂枝的化学成分。方法:采用硅胶、凝胶等色谱方法进行分离和纯化,并通过理化性质和波谱分析鉴定化合物的结构。结果:从桂枝乙醇提取物的乙酸乙酯和正丁醇萃取部分中分离得到16个化合物,分别鉴定为反式肉桂酸(1),香草醛(2),4-羟基-2-甲氧基反式肉桂醛(3),3,5-二甲氧基-4-羟基反式桂皮醛(4),(E)-3,3'-dimethoxy-4,4'-dihydroxystilbene(5),甘油-1-二十七烷酸酯(6),正二十三烷酸(7),豆甾-4-稀-3,6-二酮(8),正二十二烷酸-1-甘油酯(9),正十七烷酸(10),β-谷甾醇(11),香豆素(12),反式肉桂醇(13),3-羟基-4-甲氧基苯甲酸(14),香草酸(15),丁香醛(16)结论:其中化合物3-9,14,15为首次从该植物中分离得到。 Objective: The aim of this paper was to study the chemical constituents of Ramulus of Cinnamomum cassia. Method: The compounds were isolated and purified by silica gel column,sephadex LH-20 column chromatography. Their structures were identified by physicochemical properties and spectral data. Result:Sixteen compounds have been isolated from the Eto Ac and N-butanol fractions. They were identified as E-cinnamic acid( 1),vanillin( 2),4-hydroxy-2-methoxycinnamaldehyde( 3),sinapaldehyde( 4),( E)-3,3'-dimethoxy-4,4'-dihydroxystilbene( 5),( 2S)-1-O-heptatriacontanoyl glycerol( 6),tricosanoic acid( 7),stigmast-4-ene-3,6-dione( 8),2,3-dihydroxypropyl henicosanoate( 9),heptadecanoic acid( 10),β-sitosterol acetate( 11)coumarin( 12),E-cinnamic alcohol( 13),3-hydroxy-4-methoxy-benzoic acid( 14),vanillic acid( 15),and syringaldehyde( 16),respectively. Conclusion: Compounds 3-9,14,15 were obtained from this plant for the first time.
