Effects of different drying conditions on volatile components of Pericarpium Arecae

In the present study, the different drying temperatures and time on volatile components of Pericarpium Arecae (PA) were quantitatively and qualitatively analysed by headspace solid phase micro extraction (HS-SPME) coupled with gas chromatography-mass spectrometry (GC-MS). The matching similarity 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. As the results showed, 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. Therefore, through the accurate qualitative and quantitative analysis of volatile components in PA dry products, it is helpful to evaluate and judge the whole process, and provide a theoretical basis for its further development and utilization.
