Method for extracting glabrene and high-purity glabridin from Glycyrrhiza glabra by using ultrasonic continuous countercurrent apparatus

Abstract

Glycyrrhiza glabra is a perennial herb with strong roots and rhizomes, 0.5‑3cm in diameter, brown root bark, yellow inside, and sweet taste. There are abundant wild resources in the Greater Khingan Mountains and Inner Mongolia. In the roots and rhizome tissue cells of Glycyrrhizae glabra, there are functional components with strong anti-oxidant activity for skin depigmentation and lightening spots, and they are also the main components, namely glycyrrhizic acid (Glabrene) and glabridin (Glabridin). Because glabridin has the function of skin depigmentation and light spots with strong anti-oxidation activity, it has begun to receive attention, recognition and utilization from the foreign cosmetics industry. Low, low purity, low raw material utilization rate, high energy consumption cost for secondary refining and purification, etc., crude glabridin mostly exists in the domestic market. The invention provides a technical scheme for extracting glycyrrhizic acid and high-purity glabridin from licorice glabra by using ultrasonic continuous countercurrent equipment, which can increase the yield of finished products by 30%.

Description

technical field [0001] The invention relates to an extraction method, in particular to a method for extracting glycyrrhizic acid and glabridin in licorice glabra by using ultrasonic continuous countercurrent equipment. Background technique [0002] In the prior art, the production of glycyrrhizic acid and glabridin is mostly extracted with relatively original multifunctional extraction tank thermal reflux macroporous resin. Extraction with this method requires high extraction temperature and low extraction rate, and, in In the production process, a large amount of waste gas and waste water will be generated, which will pollute the environment. [0003] The technical problem to be solved by the present invention is to provide a technical scheme for extracting glycyrrhizic acid and glabridin in Glycyrrhizae glabra using ultrasonic continuous countercurrent equipment. On the equipment, glycyrrhizic acid and glabridin in Glycyrrhizae glabra were extracted countercurrently with ...
