目的:分析研究太白乌头地上部分甲醇提取物中石油醚萃取物的化学成分。方法:太白乌头地上部分甲醇提取后用石油醚萃取,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:共分离鉴定出28个化合物,主要为烷烃类、脂肪酸及其酯类和烯类化合物。其中含量最高的为正二十九烷(13.057%),其次为19-甲基-18,21-三十六烷二醚(8.180%)、乙二醇硬脂基醚(7.851%)、3,7,11,15-四甲基-2-十六碳烯-1-醇(7.805%)、棕榈酸甲酯(6.676%)等。结论:首次报道了太白乌头地上部分的化学成分,为陕西特有药用资源太白乌头全草的进一步研究和开发利用提供了依据。
Objective :To analyze the chemical constituents of petroleum fraction of Aconitum taipeicum. Methods:The methanol extract of Aconitum taipeicum were extracted by petroleum and then analyzed by GC-MS. The compounds were quantitatively determined by normalization method. Results:Twenty eight compounds were separated and identified. Most of them were alkane, fat acids and their esters and alkenes. The Nonacosane covered 13. 057 % of the total peaks, while 19-methyl-18,21-Hexatriacontanediether 8.180%, Eth-ylen eglycol monooctadecy ether 7. 851% ,3,7,11,15-Tetramethyl-2-hexadecen-l-ol 7. 805%, Metahyl Palmitate 6. 676% and so on. Conclusion:This is the first report of constituents from the Flower, Stem and Leaf of Aconitum taipeicum. The results will provide foun- dation for further exploitation and use of Aconitum taipeicum.
