Selected microwave extraction of eucalyptus leaves in the best technology of organic acids. Orthogonal to optimize the design of microwave extraction process, Zhaoqing, Guangzhou, Guangxi, Yunnan and four different origin of eucalyptus leaf extract for organic acids, a comparative study of microwave extraction and commonly used extraction (back extraction, extraction) of organic The acid extraction, and high performance capillary electrophoresis determination of the five kinds of organic acid content. Microwave extraction of organic acids of the five optimization process: solvent for anhydrous ether, in power for the microwave power, extraction time of 4 minutes, the amount of solvent was 300 mL, in these conditions, organic acids, the average recovery rate of greater than 90% RSD ≤ 1.24. The results showed that the microwave extraction Zhaoqing eucalyptus leaf extract has a high content of organic acids of the five, time-saving features should be extracted in traditional Chinese medicine applied.
