Abstract:In the present study，the different drying temperatures and time on volatile components of pericarpium arecae （PA） were quantitatively and qualitatively analyzed by headspace solid phase microextration （HS-SPME）coupled with gas chromatography-mass spectrometry （GC-MS）.The matching similarity between NIST and Wiley retrieval libraries and retention index （RI）were used to characterize the unknown compounds，and the contents of each component were determined by internal standard method.Finally，the significance among groups was inspected by through ANOVA and Duncan′s multiple range tests.The results showed that：a total of 23 main characteristic volatile compounds were separated and identified，including esters，organic acids，aldehydes，alcohols and alkaloids.It was found that drying at different temperatures had a great impact on esters，organic acids，aldehydes and alcohols.And there was a significant difference among the groups.As shown in the results，the content of arecoline was decreased with the higher drying temperature；while the content of homoarecoline was increased with the higher drying temperature.This may be due to the high temperature conversion of methylation of arecoline.Through the accurate qualitative and quantitative analysis of volatile components in PA dry products，it was helpful to evaluate and judge the whole process，and provided a theoretical basis for its further development and utilization.
