Embodiment 1

[0017] Example 1 Preparation of laver polysaccharide

[0018] Add 100 g of dried seaweed to 65 times the amount of water, ultrasonically crush and extract for 90 min, filter through a 200-mesh filter cloth, and collect the filtrate; Ionized water was desalted by Sephadex G-25 column chromatography, and freeze-dried to obtain Porphyra polysaccharide samples.

[0019] Analysis and Identification of Porphyra Polysaccharides

[0020] Molish reagent reaction: Take 1ml of a polysaccharide sample of a certain concentration in a small test tube, add two drops of а-naphthol reagent, mix well, slowly add 2ml of concentrated sulfuric acid, let it stand, and observe whether there is a purple ring.

[0021] Ultraviolet Spectrum: Prepared into 0.1% aqueous solution, and scanned in the range of 200-400nm to detect the presence or absence of characteristic absorption peaks.

[0022] Infrared spectrum: Grind a very small amount of polysaccharide sample with potassium bromide, press it into...

Embodiment 2

[0026] Example 2 Preparation of laver polysaccharide

[0027] Add 100 g of dried seaweed to 50 times the amount of water, ultrasonically crush and extract for 100 min, filter through a 200-mesh filter cloth, and collect the filtrate; Ionized water was desalted by Sephadex G-25 column chromatography, and freeze-dried to obtain Porphyra polysaccharide samples.

[0028] The beneficial effects of the present invention will be further illustrated by test examples below.

Embodiment 3

[0046] Example 3 Preparation of skin care lotion containing laver polysaccharide

[0047] According to the conventional process of skin care products, the skin care lotion of the present invention is prepared, and the gained skin care lotion is named as skin care lotion #1, wherein the proportioning ratio of raw materials and auxiliary materials is as follows:

[0048] Sodium Carboxymethyl Cellulose 1g

[0049] Laver polysaccharide 1g

[0050] Allantoin 2g

[0051] Chamomile 10g

[0052] Niacinamide 20g

[0053] Propylene glycol 20g

[0054] Euxyl K-100 1g

[0055] Add distilled water to 1000ml.

Abstract

The invention discloses application of porphyra polysaccharide to preparation of an ultraviolet ray injury resistant skin care product. Experiments prove that the survival rate of fibroblast damaged by ultraviolet A (UVA) radiation can be obviously improved through porphyra polysaccharide, and the porphyra polysaccharide has an obvious effect of repairing the fibroblast with ultraviolet ray injury and also has an obvious ultraviolet-proof effect. The porphyra polysaccharide is applied to the skin care product and can be prepared into various forms of cream, emulsions, facial masks, toner, skin lotion, ointment, oiling agents, gel, aerosol, solutions or coating agents.

Description

technical field [0001] The invention relates to a new application of laver polysaccharides, in particular to an application of laver polysaccharides in the preparation of anti-ultraviolet damage skin care products. Background technique [0002] Porphyra is a marine red algae, rich in protein, polysaccharides, multivitamins, minerals and other components, with high nutritional value and a variety of obvious biological functions. It is widely used in food, medicine, cosmetics and nutrition. The application prospect is very good. Laver polysaccharide is one of the main components of laver. It is a partially sulfated natural linear polysaccharide extracted from laver. It has various activities, such as anti-oxidation, anti-cancer, and enhancing cellular immunity. [0003] There are two types of ultraviolet radiation, artificial and natural, with the sun being the only natural source of ultraviolet radiation. Appropriate amount of ultraviolet radiation is beneficial to the huma...
