| titleOfInvention | Method for composite enzyme-coordinated dual-frequency ultrasonic extraction of licoflavone |
| abstract | The invention discloses a method for extracting licoflavone from glycyrrhiza waste residues, and particularly relates to a method for composite enzyme-coordinated dual-frequency ultrasonic extraction of licoflavone. The method comprises the following steps: adding 8-10fold of 70-80% ethanol solution to glycyrrhiza waste residues, adding composite enzyme which is 0.5-2% of weight of the raw material, evenly agitating, and putting into a dual-frequency ultrasonic extractor to extract, so as to obtain enzymatic hydrolysate; inactivating at high temperature, centrifuging, taking supernate, and extracting with petroleum ether; taking an ethanol layer and concentrating into 1/10 of original volume; feeding to a pre-treated macroporous absorptive resin column, eluting by 5-7BV of 80-90% ethanol, and collecting an eluent and concentrating; and recrystallizing an ethanol solution containing 1-10% hydrochloric acid, so as to obtain the licoflavone. The glycyrrhiza waste residues are taken as the raw materials, and the target of reasonable development and utilization of resources is achieved. The method is simple in process, easily available in raw materials, high in yield, and applicable to large-scale industrial production. |
