[Objective] To study the chemical components and antioxidant activity of volatile oil from FRUCTUS OCIMI BASILICI in Hetian of Xinjiang.[Method] The volatile oil was extracted by naphtha extractor and then determined by GC-MS,its chemical compositions were identified by computer retrieval technique,and the relative contents of those compositions were calculated by the method of peak area normalization.The antioxidant activities of those compositions were explored through their scavenging rate of DPPH·.[Result] A total of 65 compositions were isolated,among which 60 were identified,accounting for 92.59% of the total volatile oil components.The main compositions were linolenic acid(13.83%),n-Hexadecanoic acid(13.80%),pulegone(8.31%) and(-)-Spathulenol(6.72%).The volatile oil extracted by vapor distillation method could better scavenge DPPH·.[Conclusion] Among the chemical compositions of volatile oil extracted from FRUCTUS OCIMI BASILICI in Hetian of Xinjiang,the alcohols and ketons were the most,followed by acids and alkenes,and the volatile oil had DPPH· scavenging capacity.
