Abstract
The experiment was conducted to research the extraction method of cinnamic acid in cucumber plant,regarding cinnamic acid as phenolic acid.The result showed that supersonic extraction shortened the extraction tine,enhanced the extraction effect,and was easily operated by comparison with traditional water extraction by suoersonic extraction,the best time was 15 min to extract cinnamic acid in cucumber leaf and root and the extraction rate was nespectively raised 59.63% and 74.54% than water extraction: the best time is 20 min to extract cinnamic acid in cucumber stem and the extraction race was raised 93.59%.At the same tine,with strictly controlliny the experiment condition,the time system was established that the cucumber root,stem and leaf were by supersonic,so,the experiment offered a better extraction method to determine phenolic acid of the plant.
