Description
Technical Field
The invention relates to the technical field of cosmetics, in particular to a compound composition of glycyrrhizic anhydride and tremella polysaccharide degradation products and application thereof.
Background
Skin moisturization is the most essential requirement for skin care. The stratum corneum of human skin is mainly composed of anucleate keratinocytes, keratin filaments, amino acid compounds and natural moisturizing factors, and has the functions of retaining moisture, a barrier and the like. The water source in the stratum corneum of the skin is mainly sweat secreted by sweat glands, and 20% of water is tightly bound to natural moisturizing factors and skin lipids, so that the formed sebum membrane emulsified by sweat and water and the natural moisturizing factors become two most important factors for skin moisturizing. The moisturizing effect of cosmetics and raw materials can be evaluated by indexes such as Natural Moisturizing Factors (NMF), Aquaporins (AQPs), tight junction proteins (Claudins), Hyaluronic Acid (HA) and the like in skin keratinocytes cultured in vitro.
Aquaporins (AQPs) are proteins located on cell membranes that significantly increase the permeability of the cell membrane to water molecules. Since there are no blood vessels in the epidermis and the water in the epidermis diffuses from the dermis, AQPs between epidermal cells constitute the major pathway for intercellular water transport. To date, 13 AQPs have been found, of which AQP3 is the most abundant aquaporin subtype expressed in human skin, and AQP3 is permeable to glycerol and the like in addition to water molecules. At present, the change of AQP3 content is quantitatively detected mainly by Western Blot hybridization, immunohistochemical staining method semi-quantitative detection and commercial kit ELISA method, and can be used as one of evaluation indexes of effective components of cosmetic moisturizing effect.
At present, a great deal of research shows that glycyrrhizin (Glycyrrhiza Acid Monoamonium Salt n-Hydrate, GAMS) has the effects of resisting virus, protecting liver, reducing transaminase, regulating immunity, protecting cell membrane, relieving inflammatory reaction and the like (the clinical observation that Chaihei A-2b interferon is combined with compound glycyrrhizin to treat chronic hepatitis [ J ] Shandong medicine, 2011, 33 (1): 108-109.). The glycyrrhizic acid preparation has similar pharmacological effects to glucocorticoid medicine in anti-inflammatory effect and no obvious side effect, and may be used clinically in treating bronchitis, acute and chronic hepatitis caused by different reasons and AIDS virus resisting effect. Glycyrrhizic acid drugs are getting more and more attention, and some other effects thereof are slowly recognized. Guo et al found that AQP 3expression was increased in HaCat cells treated with appropriate concentrations of Compound Glycyrrhizin (CG), and speculated that CG may have a role in repairing skin barrier function in addition to anti-inflammatory effects (Guo Bo, Song Weimin, Hu Lingling. Effect of compound glycyrrhizin on the aqua porrin 3expression in HaCaT cell cultured in vitro [ J ]. Chinese Journal of Dermatoveneology of Integrated genetic & Western Medicine 2011, 10(4): 219-.
Golden fungus (Tremella aurantiaba, TA) is a rare and precious edible fungus, is recorded in Chinese medicinal fungi, has warm and cold properties and sweet taste, can reduce phlegm and relieve cough, is mainly used for treating diseases such as lung heat, excessive phlegm, asthma and the like, and has the effects of lubricating skin and the like due to fine colloid, white and smooth taste and fragrant smell of the golden fungus. Tremella aurantialba polysaccharides have relatively large molecular weight and are difficult to absorb, and the absorption rate of TAP by human body is improved after the molecular weight of Tremella Aurantialba Polysaccharides (TAP) is reduced, and the research on the moisturizing effect of Polysaccharide acid degradation products after the aqueous acid degradation of Tremella aurantialba has also been reported (Zhicai Zhang, Yin Li; Kechang Zhang, Application of Statistical Analysis for the Optimization of Mycelia and Polysaccharide Production by Tremella aurantia, Food Technology and Biotechnology, Volume 45, Issue 1.2007.PP 45-50).
