GC-MS analysis about volatile oil from fissistigma oldhamii

In this paper,the volatile oil from Fissistigma oldhammi was identified and analyzed by using the combination of gas chromatography–mass spectrometry( GC–MS). The results showed that the identified constituents of volatile oil contained 50 compounds whose proportion in the total fat–soluble component was 72.137%. The compounds types mainly included saturated hydrocarbons, alkenes,derivatives of aliphatic hydrocarbon,alkaloids,flavones and aromatics.In the total volatile oil,the mainly components were alkaloids(22.349%),flavones(22.192%) and derivatives of aliphatic hydrocarbon(12.237%). And the relatively highest content compound was 4',5,6, 7–tetramethoxyflavone( 22.192%),followed by 1–(9–borabicyclo3.3.1]non–9–yl)–3,5–bis(dimethylethyl)–4–ethyl–1H–pyrazole( 21.063%) and methyl oleate( 5.917%).
