OBJECTIVE:To analysis the volatile components in wild strains of Rabdosia rubescensin in Jiyuan area. METHODS: Headspace solid phase microextraction (HS-SPME) was conducted to extract the volatile components in 43 wild species of R. rubescens, GC-MS was conducted to identify the components, and peak area normalization method was conducted to calculate the relative content of the components. RESULTS:The variety and relative contents of the volatility components in 43 wild species had obvious differences and the ranges of species number and relative content was from 0 to 11 and from 0 to 84.03% respectively. Caryophyllene, caryophyllene oxide, dihydroactinidiolide, phytone and patchouli alcohol were main components which existed in a variety of different strains of volatile components of R. rubescens,and were mainly composed of terpenes, ketones, alcohols and esters. In addition,fatty acids such as palmitic acid, oleic acid and linoleic acid were contained in a few individual varieties. CONCLUSIONS:The internal quality in 43 wild species of R. rubescens has certain differences.
