[Analysis of petroleum fraction of Aconitum taipeicum by GC-MS].

ABSTRACT

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.
