ABSTRACT
OBJECTIVE:
To optimize the ultrasonic-assisted extraction technology of total flavonoids from Tibetan Scindapsus aureu.METHODS:
The single-factor test was adopted to investigate the effects of extraction time,extraction temperature,the vol-ume fraction of ethanol,the ratio of liquid to solid and power on the extraction rate of total flavonoids from Tibetan Scindapsus au-reu in the process of ultrasonic-assisted extraction,based on which,four-factor and five-level Box-Behnken central component de-sign was performed with unchanged ultrasonic power,and then response surface method was adopted to analyze the effects of the 4 factors and their interaction on the extraction rate of total flavonoids to determine the optimal factor and level,and verification tests were conducted.RESULTS:
The optimal ultrasonic-assisted extraction technology was as follows as extraction time of 29 min,tem-perature of 44 ℃,volume fraction of ethanol of 78%,ratio of liquid to solid of 13∶1(ml/g). In three verification tests,the aver-age extraction rate of total flavonoids was 2.130%,with an relative error of 0.005% compared to the theoretical value. CONCLU-SIONSThe optimal technology is reasonable and feasible,and can be used for theultrasonic-assisted extraction of total flavonoids from Tibetan Scindapsus aureu.
