| Abstract: | The flavonoids was extracted from silkworm feces through ultrasonic-assisted extraction and the influences of alcohol concn.ex-traction temperature and treating time on extraction rate of flavonoids were studied through single factor experiments.The results showed that the optimum technological condition for ultrasonic-assisted extraction of flavonoids from silkworm feces was as follows:the alcohol concn.was 30% ,the time of ultrasonic extraction was 35 min and the extraction temperature was 70 ℃.Under this condition,the extraction rate of fla-vonoids from silkworm feces was 2.358% . |
