太白乌头石油醚萃取部分的GC-MS分析

Analysis of Petroleum Fraction of Aconitum taipeicum by GC-MS

目的:分析太白乌头甲醇提取石油醚萃取部分的化学成分。方法:甲醇提取太白乌头后用石油醚萃取,GC-MS法分析和鉴定其化学成分,并采用峰面积归一化法计算各成分相对百分含量。结果:共分离出38个化合物并鉴定出其中的33个,鉴定的成分占流出峰面积的97.28%。大部分为脂肪酸及其酯类、甾类和烯类化合物。含量最高的为棕榈酸(12.083%),其次为豆甾-4-烯-3-酮(10.184%)、1-亚油酸单甘油酯(8.962%)、(顺,顺)9,12-十八二烯酸(8.054%)等。结论:首次报道了太白乌头的非生物碱成分,为太白乌头资源的进一步开发利用提供了依据。

Objective ： To analyze the chemical constituents of petroleum fraction of Aconitum taipeicum. Methods ： The methanol extracts of Aconitum taipeicum were extracted by petroleum and then analyzed by GC-MS. The compounds were quantiatively determined by normalization method. Results：Thirty-eight compounds were separated and thirty-three compounds that covered 97. 28% of the total peaks were identified. Most of them were fat acids and their esters,steroids and alkenes. The n-Hexadecanoic acid covered 12. 083% of the total peaks, while Stigmast-4-en-3-one 10. 183%, Linolein, 1-mono-8.96%, 9,12-Octadecadienoic acid （ Z, Z）-8. 054% and so on. Conclusion ：This is the first report of constituents of Aconitum taipeicum except alkaloids. The results will provide foundation for further exploitation and use of Aconitum taipeicum.
