Polysaccharide mixture with skin whitening effect and method for manufacturing polysaccharide mixture

Abstract

The invention relates to the technical field of cosmetics, in particular to a polysaccharide mixture with a skin whitening effect and a method for manufacturing the polysaccharide mixture. The polysaccharide mixture with the skin whitening effect comprises, by weight, 40-50 parts of radix paeoniae alba polysaccharides, 20-25 parts of angelica sinensis polysaccharides and 20-25 parts of angelica dahurica polysaccharides. The radix paeoniae alba polysaccharides, the angelica sinensis polysaccharides and the angelica dahurica polysaccharides are mixed with one another to obtain the polysaccharide mixture. The polysaccharide mixture and the method have the advantages that ethanol precipitation conditions are controlled, so that ineffective polysaccharide ingredients in the total polysaccharides of radix paeoniae alba, angelica sinensis and angelica dahurica can be abandoned, polysaccharide active portions, which are capable of obviously suppressing tyrosinase, suppressing generation of melanin and realizing the excellent skin whitening effect, in the total polysaccharides can be screened, the purity of functional polysaccharides of the active portions can be greatly improved, the purity of active polysaccharide ingredients with skin whitening and anti-oxidation effects can be improved, and the activity of the polysaccharide mixture can be enhanced; active polysaccharide components extracted from three traditional Chinese medicinal materials which are the radix paeoniae alba, the angelica sinensis and the angelica dahurica are mixed with one another according to certain proportions and are coordinated with one another, so that the excellent effects can be realized.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a polysaccharide mixture with whitening effect and a preparation method thereof. Background technique [0002] Tyrosinase is the main limiting enzyme in the biosynthetic pathway of melanin. At present, whitening cosmetics mainly reduce the formation of melanin in the skin by inhibiting tyrosinase. To study the whitening effect, the tyrosinase inhibition test is generally used as the evaluation of the whitening effect, which is generally accepted by scholars. There are many kinds of whitening cosmetics on the market, but most of them contain chemical ingredients, which may have some adverse effects on the skin, and even have carcinogenic effects. Tyrosine inhibitors derived from natural medicines are green and safe, not only effective for pigmented skin diseases, but also of great significance in the formulation of whitening beauty cosmetics.

Problems solved by technology

[0006] It can be seen from the above description that there are also researches on Radix Paeoniae Alba, Angelica and Angelica dahurica in the prior art, but they mainly focus on the application of whole medicines, in the fields of health food, medicine and extraction technology, and there are also literature reports on some polysaccharide extracts of traditional Chinese medicine or their combinations. However, these traditional Chinese medicine polysaccharides have a large molecular weight range and are a mixture. It can be said that they are the total polysaccharides of a certain traditional Chinese medicine. The components that can play a whitening effect or free radical scavenging function are only a part of the total polysaccharides. The activity of other parts is too low or basically ineffective, so the total polysaccharides of traditional Chinese medicine contain active ingredients and inactive ingredients that have no effect at the same time, which greatly reduces the whitening effect or free radical scavenging effect, and the purity of the active polysaccharide components is also low. greatly reduced
