ABSTRACT
OBJECTIVE:
To optimize the extraction conditions of total flavones from Pueraria Lobata by ultrasonic method.METHODS:
The uniform design method was applied to investigate the effects of alcohol content,the quantity of solvent,extraction time,extraction temperature and the extraction times on the result of extraction.The content of total flavone of Pueraria Lobata was determined by ultraviolet-visible spectrophotometry.The extraction conditions were optimized with the extraction yield and the mass fraction of total flavone of Pueraria lobata in the extract as indexes.RESULTS:
The optimal extraction conditions were as followsextracting with 75% alcohol(20 mL?g-1) for 40 min(extraction time) at 68 ℃(extraction temperature) for a total of 5 times.CONCLUSION:
The extraction process is reasonable and feasible and it provides theoretic basis for the industrialized production.
