Abstract:
The extraction technology of flavonoids in the bulb of Lilium lancifolium Thunb. was studied by comparing the ultrasonic wave extraction technology with the traditional extraction technology. The results showed that the ultrasonic method was better. Also, the optimal procedure for the ultrasonic wave method were studied. Under the conditions of 1:30 of 80% ethanol to the bulb of Lilium lancifolium Thunb. weigh ratio, ultrasonic treatment for 40 min twice at the temperature of 70 degrees C, the average extraction rate of flavonoids was as high as 99.25%.
