Problems solved by technology

[0005] So far, there are not many domestic literatures on the preparation of bletilla striata polysaccharides. Even if there are, the sevag method is commonly used to remove proteins. This method is not efficient. The refining process of bletilla striata polysaccharide gum is obtained. This method improves ...

Embodiment Construction

[0052] The invention discloses a bletilla striata polysaccharide complex as a raw material for cosmetics. The complex contains small molecule bletilla striata polysaccharides of 20-80KDa and bletilla striata polysaccharides of 500-700KDa, and the weight ratio of the former to the latter is 1:1-1: 20.

[0053] The bletilla striata polysaccharide complex comprises the following steps:

[0054](1) Prepare the small molecule bletilla striata polysaccharide according to the following steps:

[0055] Step 1: crushing: crushing the dried bletilla striata tubers to 100 mesh;

[0056] Step 2: Rough extraction: adding 70-75% ethanol aqueous solution to boil, the mass-volume ratio of Bletilla striata tuber crushed material to ethanol liquid is 1:5-1:20, repeat the extraction three times, remove fat-soluble components and plant pigments, and collect the precipitate;

[0057] Step 3: Re-extraction: add deionized water to the precipitate, heat and maintain the temperature at 50-55°C, stir...

Abstract

The invention provides a bletilla polysaccharide compound serving as a cosmetic raw material and a preparation method thereof. The method comprises the following steps of: treating bletilla tubers by steps of drying, crushing, extracting, enzyme treatment, concentration, drying and the like, then preparing the bletilla polysaccharide into small molecular bletilla polysaccharide with certain molecular weight by enzyme processing treatment and chromatographic refining, and compounding the bletilla polysaccharide and the small molecular bletilla polysaccharide into the bletilla polysaccharide compound in a ratio of 1:1-1:20. The bletilla polysaccharide compound and the preparation method have the advantages that: the protein removal efficiency of the method is higher, the production process is environment-friendly, the post treatment of the product is simple and easy to operate, the production process is simplified, the production cost is reduced, and the bletilla polysaccharide compound is applied to cosmetics for the first time.

Description

technical field [0001] The invention relates to a bletilla striata polysaccharide complex as a cosmetic raw material and a preparation method thereof, and a whitening, moisturizing and anti-aging cosmetic, belonging to the technical field of deep processing of natural plants. Background technique [0002] Bletilla striata (Bletillast riata Reichb.f.) Bletilast riata Reichb.f., also known as Bletilast riata Reichb.f., orchid family Bletilla striata, also known as small bletilla striata, lotus and grass, sweet root, white root, bamboo millet gum, Xuerulai, purple orchid (root), etc., are often found in shaded grass or moist under forest It is named because of its white root color and continuous growth. It is distributed in my country, Japan and Ryukyu. [0003] Modern research analysis shows that Bletilla striata contains a large amount of plant polysaccharides, the content of which is about 40% to 50% in dry bulb tissue. These polysaccharides are mainly composed of β-1,4-manno...
