Abstract: To develop a simple gas chromatography method for simultaneous determining aldehydes and phenols in hawthorn seeds dry distillated oil.Firstly,a systematic characterization strategy by using GC-MS/MS analysis was carried out and the relative contents of the compounds were determined by using the normalization method.The NIST identified 62 compounds,The main components are aldehydes which account for 55.96% of the total content,The content of an GC-FID method for determination of main components in hawthorn seeds dry distillated oil (furfural,guaiacol,2,6-two methyl phenol,2-methyl phenol,phenol,2-methoxy-4-methyl phenol,2,6-two methoxy phenol,Tetrachloroguaiacol,1,2,3-trimethyl benzene,3,4,5-Trimethoxy toluene),The recovery range is 100.06%-102.44%,and the range of RSD is 298%-4.57%.In conclusion,the established GC-FID test method is simple,rapid,accurate,sensitive and reproducible.It is suitable for the quantitative analysis of the 10 active compounds in hawthorn seeds dry distillated oil.
