[Study on Ultrasonic-Surfactant Extraction of Total Flavonoids from Albizia julibrissin Flower by Response Surface Methodology].
OBJECTIVE
To optimize the extraction technology of total flavonoids from Albizia julibrissin flower by combining surfactant with ultrasonic technology.


METHODS
Using Box-Behnken central composition design and response surface methodology, the effects of surfactant concentration, liquid-solid ratio and ultrasound time on the yield of total flavonoids were studied based on the extraction rate to determine the optimum extraction conditions of total flavonoids.


RESULTS
Optimum conditions for extraction of Albizia julibrissin flower were as follows: mass percentage of 2. 5% SDS,15 times of 60% ethanol,ultrasonic time of 31 min. Under these conditions,the extraction rate of total flavonoids from Albizia julibrissin flower was 0. 853%. Using this technology, the extraction yield increased by 93. 0% as compared with that using ultrasonic technology alone.


CONCLUSIONS
The optimum extraction technology can be used for extraction of total flavonoids from Albizia julibrissin flower for its simplicity and responsibility.
