继树兰花净油的分析之后,我们用气相色谱-质谱-数据系统联用技术以及红外和核磁共振光谱分析了树兰花水汽蒸馏挥发油的化学成份。发现其萜烯部分有:α-橙椒烯、(王古)(王巴)烯、丁香烯、双环榄香烯、蛇麻烯、β-檀香烯、γ-木罗烯、双氢姜黄烯、α-木罗烯、β-没药烯、白菖烯、甜旗烯。其含氧部分有甲基庚烯酮、2-乙基己醇-1、橙做醇、表-橙椒醇、丁香烯环氧物、乙酸苄酯、苄醇、蛇麻二:烯酮、芳萜醇、表-苦本醇、蛇麻烯环氧物Ⅰ、蛇麻烯环氧物Ⅱ、T-荜澄茄醇、蛇麻醇、δ-荜澄茄醇、荜澄茄烯醇、丁香二烯醇、蛇麻烯-7醇和茉莉酮酸甲酯。 相似文献

七里香蔷薇花属蔷薇科蔷薇属,学名Rosa banksia R.Br.normalis Regel。它大量地野生在我国秦岭山区。我们采用了甘肃省成县地区的七里香浸膏~*。将它用乙醇在0℃时脱蜡三次,脱蜡后的净油用硅胶柱层析,并将其粗分成萜烯和含氧部分两段。取其含氧部分用气相色谱-质谱联用仪进行分析鉴定。重建总离子流(RIC)色谱图上有64个主峰(见图1、2)。把这些谱图对31,000个化合物的EPA/NIH/MSDC谱库进行检索并对照了其它已发表的谱图(EPA/NIH Mass SpectralData Base;Mass Spectrometry Data Centre,Eight Peak Index of Mass Spectra等),鉴定出15个化合物,它们是:丁香酚,甲基丁香酚,γ-紫罗兰酮,二氢β-紫罗兰酮,α-紫罗兰 相似文献

上犹八角茴香挥发油化学成份的研究 总被引:3,自引:0,他引:3
八角茴香(Illicium verum Hook,f.)系木兰科(Magnoliaceae)八角属常绿乔木,是我国特产的芳香植物。主要分布于广西、广东、贵州、云南等省区。江西北纬26°以南地区从五十年代初开始引种。八角茴香的果实是广泛使用的调味香料,入药则有温中理气、健胃止呕的功效,并有很强的抑菌作用。 相似文献

线叶旋复花化学成份的研究 总被引:1,自引:0,他引:1
Xian-Ye-Xuan-Fu-Hua, the flowers of Inula linariaefolia Turcz (Compositae), is a commonly known Chinese medicinal herb and used as expectorant as well as for the treatment of some malignant tumors. The chemical investigation of its active principles by our early work in 1964 resulted in the isolation of a new sesquiterpene lactone (m.p. 190-192`C, (α)D-24 in CHCl3), which possesses significant inhibitory action against Hela cells and fungi in vitro. Besides, it also shows some expectorant activity in preliminary pharmacological tests. Analyses of the spectral data (IR, UV, ^1H NMR, 13C NMR, MS) and our early results of chemical reactions suggested that the compound is the same as britanin 1 (m.p. 192-194`C, (α)D-26 in CHCl3) studied Chugunov in 1971. However its stereochemistry remained unsolved. On careful examination of the 360 MHZ 1H NMR data (in CDCl3 and in C6D6) and the Cotton effects of ORD spectra of its saturated lactone and cyclopentanone derivatives, we considered that britanin must be ambros-11(13)-en-2β, 4β, 6α, 8α-tetraol-12-oic-(12,8)- lactone, 2, 6-diacetate (7). Since the large values for J6,7, J7,8, J8,9, J9,10 and J1,10 indicate the existence of successive a-a trans coupling in all vicinal protons form C6 to C1, the cofnformation of the cycloheptane ring must be in chair from. The other constitutent isolated from the same plant has been identified as taraxasteryl palmitate. 相似文献
