Analysis And Comparison For Main Volatile Compounds Of Pericarpium Arecae In Different Drying Methods

The main volatile compounds of Pericarpium Arecae (PA) dried by different methods were analysed via SPME-GC-MS combined with retention index (RI) method and standard. There were multiple volatile components of the PA dried by the five methods respectively identified; meanwhile, each one was quantified by area normalization method. The results indicated that the content of arecoline, the index constituent, was low in sample F (5.11%) and sample BD (6.97%), but high in sample D (38.88%), sample MFMD (26.45%) and sample HFMD (35.64%). It can be seen that drying has less damage to the known active ingredients such as arecoline. The microwave drying method of middle fire (MFMD) had better effect to get comprehensive ingredients, due to less damage to volatile components. In conclusion, different drying methods have great influence on the volatile components of PA. And the drying method (D) has a great advantage on the active components such as arecoline. However, the method (MFMD) has less time consuming and can preserve more complete volatile components.
