The application discloses a kind of
matrine high-efficiency
extraction methods based on
microwave cooperation ultrasonic auxiliary, comprising the following steps: S1:
Sophora flavescens
raw material pretreatment;S2: pre-soaking treatment;S3:
microwave cooperation ultrasonic extraction, the mixture after pre-soaking is placed in extraction device, first
microwave processing is opened,
microwave power 300-400W, frequency 2450MHz,
processing 5-8min;Keep microwave open state, synchronous opening ultrasonic
processing, ultrasonic power 150-200W, frequency 40-60kHz, microwave and ultrasonic cooperation processing 10-15min;S4: multistage
filtration purification, after extraction mixture is filtered first through 200 mesh filter cloth, collect initial filtrate;Then the initial filtrate is filtered by
ceramic membrane, collect membrane filtrate;S5: concentration
crystallization;S6: separation and
drying.The application is by freeze-thaw pretreatment, compound infiltration liquid infiltration and microwave-ultrasonic cooperation extraction combination process, greatly improve the
dissolution efficiency of
matrine, extraction time is shortened by more than 60% compared with traditional
solvent extraction method, and extraction rate is increased by more than 30%.
