Embodiment 1

[0034] A method for extracting Polygonatum polyflora extract, comprising the following steps:

[0035] Step 1: wash and dry the rhizome of Polygonatum multiflora with deionized book, slice, crush and sieve to obtain 200 mesh Rhizome of Polygonatum multiflora powder;

[0036] Step 2: Extract 1.00g of Polygonatum multiflora rhizome powder in 20.00mL of hot water at a temperature of 80°C for 2 hours to obtain an extract; take the extract to measure its molecular weight by high-performance anion chromatography, and the molecular weight distribution range is 3.696×10 3 ~1.017×10 6 Da, the resulting extract was concentrated in vacuo at 55°C and a pressure of 220mbar for 2 to 2.5h to obtain the Polygonatum multiflora extract with a final concentration of 0.25g / mL (referring to the deionized water used for 0.25g sample). After extraction, vacuum concentration to 1mL), the main components are polysaccharides, proteins and polyphenols, with a mass ratio of 34.26:0.043:0.223, and also c...

Abstract

The invention discloses an extraction method and application of a polygonatum cyrtonema extract. The extraction method of the polygonatum cyrtonema extract comprises the following steps: extracting polygonatum cyrtonema rhizome powder in water to obtain an extract; and carrying out vacuum concentration on the extract to obtain the polygonatum cyrtonema extract. The polygonatum cyrtonema extract extracted by taking water as an extraction solvent mainly contains polysaccharide and also contains a small amount of protein and polyphenol; the polygonatum cyrtonema extract extracted by the extraction method disclosed by the invention has multiple effects including a moisturizing effect, an inflammation resisting effect, an oxidation resisting effect and the like when applied to cosmetics. The extraction method of the polygonatum cyrtonema extract is easy to operate and mild in conditions; and the obtained polygonatum cyrtonema extract has good stability and applicability when applied to cosmetics and has good industrial application prospects.

Description

technical field [0001] The invention relates to a method for extracting Polygonatum polyflora extract and its application, and belongs to the technical field of cosmetics. Background technique [0002] Polygonatum Polygonatum is a perennial herb of Liliaceae Polygonatum, which is used as medicine with rhizomes. It is one of the plants with the same origin of medicine and food in my country. Polygonatum is mainly divided into three types, namely Polygonatum Polygonatum, Polygonatum Polygonatum and Polygonatum Polyflora. Polygonatum multiflora is widely distributed in my country, mainly concentrated in Anhui, Hunan Xinhua, Guizhou Zunyi and Yunnan. Polygonatum multiflora contains polysaccharides, brass, polyphenols, lignin and alkaloids and other active substances, which have pharmacological effects such as anti-inflammatory, antibacterial, anti-oxidation and enhancing immunity. [0003] With the development of the economy, consumers prefer safe and green natural cosmetics, ...
