Research on the Extraction of Dendranthema Morifolium Volatile Oils by Microwave-Assisted Steam Distillation Extraction

Abstract:

Microwave-assisted steam extraction system combines the advantages of both conventional and modern technologies. MAE is probably going to be the leading technology in essential oil producing industry. In our research, one-factor and uniform experimental designs are used to determine the optimum extraction conditions, and the results are as follows: the extraction yield is measured as 2.30% with 3h of reflux time, when degree of pulverization is 90, immersing time is 3h, yield of solid to liquid equals 12: 1 ml/g. The chemicals in the production were examined by GC-MS. More than 40 kinds of chemicals were detected, which is consistent with that of the traditional steam extraction method. However, the extraction efficiency is dramatically increased when the steam extraction is assisted with microwave heating, and it is up to 3.8 times.
