Volatile Compounds in Two Camellia chrysantha (Hu) Tuyama Species

摘要

In the study,the volatile compounds in two Camellia chrysantha(Hu) Tuyama species were extracted and analysed by simultaneous steam distillation and extraction(SDE) and gas chromatography mass spectrometry(GCMS),respectively.The relative contents of the chemical constituents in the volatile components were quantified by peak area normalization and NIST database.A total of 60 volatile components were identified,45 for Camellia nitidissima and 26 for Camellia euphlebia.Aldehydes and acids were the most dominant volatiles in Camellia nitidissima,but for Camellia euphlebia there were hydrocarbons and ketones.Hexanoic acid,4-(2,6,6-trimethyl-1-cyclohexenyl)-3-buten-2-one,cis-2-decenal,4-[2,2,6-trimethyl-7-oxabicyclo[4.1.0]hept-1-yl]-3-buten-2-one,phenylacetaldehyde,eicosane,alpha-ionone,geranylacetone 2,6-di-tert-butyl-4-methylphenol,7,9-di-tertbutyl-1-oxaspiro[4,5]deca-6,9-diene-2,8-dioi and tetradecanal were both in two Camellia chrysantha(Hu)Tuyama species.
