Embodiment 1

[0023] Embodiment 1: the preparation of rose acid pectin polysaccharide

[0024] (1) Polysaccharide extraction:

[0025] Weigh 300g of roses, add 4L of ethanol solution with pH=2, mass fraction 65%, heat to 65°C, keep for 3 hours, filter, repeat 4-5 times until the solution is basically colorless. Filter and wash the roses with water until neutral, add deionized water to 3L, heat to 95°C and stir for extraction for 3 hours, filter, repeat the extraction of the filter residue twice, combine the filtrates, concentrate and centrifuge to remove impurities. The supernatant was precipitated with 3 times the volume of ethanol (same as the ethanol used for degreasing, pH = 2, mass fraction 65%), left to stand overnight, centrifuged to obtain a precipitate, and dried at 50°C to obtain rose crude polysaccharides.

[0026] Wherein: ethanol with pH=2 is prepared by adjusting the pH of ethanol to 2 with hydrochloric acid.

[0027] (2) Polysaccharide decolorization:

[0028] Dried rose c...

Embodiment 2

[0031] Embodiment 2. rose acid pectin polysaccharide

[0032] (1) Select a glass plate of 7.5cm × 7.5cm, paste 3M microporous adhesive tape, place it in a desiccator equipped with color-changing silica gel, and dry it to constant weight. Each 0.1 g of pectin acidic polysaccharides was dissolved in 10 ml of deionized water to prepare a solution.

[0033] (2) Mark each glass plate, weigh it with an analytical balance, and record it as m 0 .

[0034] (3) Use a pipette gun to absorb 100 μl of the prepared glycerin, hyaluronic acid, and polysaccharide solution, spread it evenly on a glass plate with 3M adhesive tape, weigh it with an analytical balance, and record it as m 1 .

[0035] (4) Put the weighed glass plate into a desiccator with a humidity of 44±5% (controlled by saturated potassium acetate solution), and record the specific humidity and temperature each time.

[0036] (5) After standing for a certain period of time, weigh them separately, 2, 4, 6, 8, 24h, record it as ...

Abstract

The invention relates to a preparation method and moisturizing application of acidic pectic polysaccharide from roses. Moisturizing experiments show that the rose acidic pectic polysaccharide has a remarkable moisturizing effect, and has market application values in medical supplies and cosmetics, which have moisturizing efficacies.

Description

technical field [0001] The invention relates to polysaccharides extracted from Chinese herbal medicines, more specifically, an acid pectin polysaccharide extracted from roses, its preparation method and its application in the preparation of cosmetics and medical supplies with moisturizing effect. Background technique [0002] Rose is the flower of Rosaceae rose and double rose. Rose and double rose are deciduous shrubs, native to northern China, and are now cultivated all over the country. Most of them are Shandong, Jiangsu, Zhejiang and Guangdong. The medicinal value of roses has been recorded in ancient my country. "Compendium of Materia Medica Supplements" clearly records: "There are two kinds of roses, purple and white, the purple one enters the blood, the white one enters the air, and its purple flowers are used for medicine, and the petals see fire." Roses are sweet and slightly bitter in taste, slightly warm in nature, and return to the liver, spleen, and stomach m...
