To　analyze　the　chemical　constituents　of　petroleum　fraction　of　Aconitum　taipeicum.The　methanol　extracts　of　Aconitum　taipeicum　were　extracted　by　petroleum　and　then　analyzed　by　GC-MS.　The　compounds　were　quantiatively　determined　by　normalization　method.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.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.
