Analysis of Volatile Components in Wild Strains of Rabdosia rubescens in Jiyuan Area / 中国药房

ABSTRACT

OBJECTIVE:To analysis the volatile components in wild strains of Rabdosia rubescensin in Jiyuan area. METH-ODSHeadspace 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 es-ters. In addition,fatty acids such as palmitic acid,oleic acid and linoleic acid were contained in a few individual varieties. CON-CLUSIONSThe internal quality in 43 wild species of R. rubescens has certain differences.
