Abstract
17 volatile organic acids in tinctures of Radix angelica Pubescens,coffee,date,cacao,licorice,ling vanilla,hop,fenugreek,Aglaia odorata,vanilla for the use of tobacco were determined. The samples were extracted with ASE,then derived with N,O-bis (trimethylsilyl) trifluoroacetamide,and determined by GC/MS under SIM SCAN modes. The results showed that:1) the recoveries of the acids ranged from 76.62% to 107.60% with RSDs below 10.43%; 2) formic,acetic,propanoic,butyric,pentanoic,hexanoic,lactic,2-furoic,heptanoic,benzoic,octanoic,nonanoic,and decanoic acids were found in all tincture samples,and the majority were formic,acetic,lactic,2-furoic,and benzoic acids,while neither 3-methylvaleric acid nor 4-methylvaleric acid was detected. Minor 2-methylbutyric acid was identified in coffee and cacao tinctures,3-methylbutyric acid was found in fenugreek,coffee,cacao,hop,Aglaia odorata,and date tinctures,which was one of the major acids in hop tincture.
