Glycyrrhiza glabra extract and preparation method and application thereof

Abstract

The invention discloses a glycyrrhiza glabra extract and a preparation method and application thereof. The preparation method comprises the following steps: S1, selecting roots and rhizomes of fresh glycyrrhiza glabra, then putting the selected roots and rhizomes of the fresh glycyrrhiza glabra into an ultrasonic cleaning machine, cleaning the roots and rhizomes of the fresh glycyrrhiza glabra through the ultrasonic cleaning machine, and cleaning impurities and pesticides on the surfaces of the roots and rhizomes of the fresh glycyrrhiza glabra; and S2, then taking out the cleaned roots and rhizomes of the fresh glycyrrhiza glabra, putting the roots and rhizomes into an electrothermal blowing drying box, and drying the cleaned roots and rhizomes of the fresh glycyrrhiza glabra through theelectrothermal blowing drying box. The process is simple to operate, industrial production is easy to realize, and the obtained product is clear in component, free of solvent residue risk, and safe and effective when being applied to series of cosmetic products.

Description

technical field [0001] The invention relates to the technical field of licorice glabra extract, in particular to a licorice glabra extract and its preparation method and application. Background technique [0002] Glycyrrhiza glabra root extract: Glabridin, the stem of a specific variety or Glycyrrhiza glabra L. Glycyrrhiza glabra extract can penetrate deep into the skin and maintain high activity, effectively inhibiting the activity of various enzymes (such as inhibiting tyrosinase) in the process of melanin production. It is a fast, efficient, safe and green cosmetic additive for whitening and freckle removal. At the same time, licorice glabra extract also has the effects of preventing rough skin, anti-inflammation, and antibacterial. Italian research also confirmed that Glabridin has an appetite suppressant effect, and it can reduce fat without losing weight. [0003] Glycyrrhiza glabra root extract can inhibit the activity of tyrosinase, and can also inhibit the interco...

Problems solved by technology

[0004] Therefore, it is very necessary to add Glycyrrhiza glabra extract in cosmetics, but the existing preparation methods of Glycyrrhiza glabra extract are mainly extracted by traditional methods such as steaming, water extraction and alcohol precipitation, and the main component of Glycyrrhiza glabra extract is Glycyrrhizin, the flavonoid compound represented by glabridin is insoluble in water but soluble in organic solvents. Therefore, organic solvents are commonly used to extract the active ingredients of Glycyrrhiza glabra. The most obvious disadvantage of this type of method is the residual solvent, which leads to There are greater safety risks in actual use, such as allergies, skin toxicity, etc.
