摘要：

The organic acids in Hawthorn fruits from Henan Huixian and Tongbai Mountain were determined by gas chromatography-mass spectrometry method and 23 organic acids were identified.The main organic acids in Hawthorn fruit were linoleic acid,oleic acid,linolenic acid,Citric acid,and hexadecanoic acid.There are almost the same kinds of organic acids in the two samples,but the contents of the organic acids in the two samples were very different.The contents of 8 main organic acids in Hawthorn fruits were determined by GC-MS selected ion monitoring(SIM)using internal standard curve method.The added standard recovery of the method was in the range of 92.8～103.2%,the relative standard deviations(RSD)were less than 3.5%,the correlation coefficients were more than 0.999 and the detection limits were in the range of 1.0～2.5 mg/L.
