Abstract:Gas chromatography（GC）with internal standard was used to establish a method for analysis of octacosanol and triacontanol in rice brane fatty alcohol.Triphenylbenzene was used as internal standard.The separation of target components was performed on a HP-5 capillary column.The recoveries of octacosanol and triacontanol were 99.41%（relative standard deviation，RSD）3.28%and 99.48%（RSD 3.17%），respectively.The established method was suitable for the analysis of octacosanol and triacontanol in rice brane fatty alcohol，and could provide reference for the judgment of product quality.
