Licorice extract is a medicinal component extracted from licorice. Licorice extract generally includes: glycyrrhizin, glycyrrhizic acid, glycyrrhizin, glycyrrhizic flavonoid, metabitanin, anthocyanin, quercetin, etc. It is yellow to brownish yellow powder. It has the effects of invigorating the spleen and replenishing qi, clearing heat and detoxifying, eliminating phlegm and relieving cough, relieving pain slowly and harmonizing various drugs. It is used to treat spleen and stomach weakness, fatigue, palpitation and shortness of breath, cough and phlegm, abdominal pain and limb contracture.
Licorice is a plant with great medicinal value, which is used by both Chinese and Western medicine. Western medicine has used licorice as expectorant, cough suppressant and sweet additive since ancient Greece. In the ancient Chinese Pharmacology "Shennong's Classic of Materia Medica", licorice is described as a medicine to strengthen muscles and bones, increase physical strength and treat wounds, and it is listed as the top grade. It is called the king of many drugs, and there are few prescriptions that are not used.
In traditional Chinese medicine, liquorice is classified as heart, lung, spleen and stomach meridians; It has the effects of invigorating the spleen and replenishing qi, clearing heat and detoxifying, eliminating phlegm and relieving cough, relieving pain slowly and harmonizing various drugs. It is used to treat weakness of the spleen and stomach, fatigue, palpitation and shortness of breath, cough and phlegm, abdominal and limb contracture and pain, carbuncle and sore poison, and relieve drug toxicity and intensity. The dosage is 1.5-9mg.
Research shows that licorice has the effects of inhibiting monoamine oxidase, inhibiting aldose reductase that causes diabetes, relieving spasm and analgesia, preventing and treating viral hepatitis, treating senile osteoporosis, resisting leishmaniasis, cancer, and AIDS virus.
Its efficacy is reflected in whitening and sunscreen:
The whitening effect of licorice extract is mainly to prevent the formation of melanin by inhibiting the activity of tyrosinase and dopa pigment tautometase (TRP-2) and blocking the polymerization of 5,6-dihydroxyindole (DHl), thus achieving the effect of whitening skin.
In licorice extract, the components with sunscreen effect are generally flavonoids. Due to the conjugation of the molecular structure of licorice flavonoids, they show strong absorption to both ultraviolet and visible light. Molecules that absorb high-energy ultraviolet light, transition from the ground state to the active state, and then return from the active state to the ground state, releasing harmless low-energy rays. Compared with synthetic sunscreen, licorice extract used as sunscreen does not need to add antioxidants in the formula, will not stimulate the skin, and has strong stable absorption capacity.
Take the dried roots and rhizomes of Glycyrrhiza uralensis, G. inflata or G. Glabra, and remove the raw materials for drying fibrous roots. After soaking in warm water less than 60 ℃, cut into thin slices less than 0.5 cm, add 8 times of water, boil and extract in countercurrent circulation for 8 times, place the extract in the settling tank for natural sedimentation for 3 hours, take the supernatant and concentrate it to a thick paste, so that the content of glycyrrhizic acid is not less than 20%, which is liquorice extract. Take the liquorice extract and add a proper amount of water, continuously stir and heat it to melt and filter, slowly add 85% ethanol into the filtrate until the ethanol content in the solution reaches about 65%, leave it standing overnight, take the supernatant, add 65% ethanol to the remaining precipitate, stir and overnight, take the supernatant, add 65% ethanol to extract once, combine three extracts to filter and recover ethanol, use water and ethanol to make the glycyrrhizic acid content more than 7.0%, and ethanol content 20%~25%, Adjust the Ph value to 7.5~8.5 with ammonia solution, then stand still and clear, and filter the supernatant.
