Abstract
The invention discloses an extraction process of cucurbitacin E; the extraction process comprises the following steps: 1) sending muskmelon pedicels into a pulverizer, and pulverizing to obtain pulverized muskmelon pedicels; 2) refluxing and extracting the pulverized muskmelon pedicels with ethanol for twice to obtain an extract liquid; 3) concentrating the extract liquid and separating to obtainan ethyl acetate layer; 4) concentrating the ethyl acetate layer to dry, adding 4 equivalent weight of reduced iron powder and 8 equivalent weight of glacial acetic acid, refluxing for 50-70 min, andseparating to obtain cucurbitacin E. 4 equivalent weight of reduced iron powder and 8 equivalent weight of glacial acetic acid are adopted, a large amount of cucurbitacin B in the muskmelon pedicles is converted into the cucurbitacin E, separation extraction is performed, the extract rate of the cucurbitacin E is greatly improved, the process is simple, and the cost is low.
