Problems solved by technology

However, polyphenol molecules are highly polar, and in CO 2 The solubility in the fluid is small, and the yield of direct extraction is not high. It is necessary to increase the solubility of phenolic substances by adding ethanol and other polar entraining agents, so as to improve the extraction effect. However, there are few reports on the extraction and comprehensive utilization of seaweed polyphenols. , especially some red algae plants are rich in seaweed polysaccharides such as agar, and the characteristics of agar, etc., which melt and condense when exposed to water, make the extraction methods of such seaweed polyphenols limited, and the extraction efficiency is not high

Embodiment 1

[0039] a CO 2 The method for supercritically extracting polyphenols from agaricus cauliflower specifically comprises the following steps:

[0040] Step 1) Wash the fresh Geliflower, drain it, and then place it in a vacuum drying oven at 50° C. for vacuum drying until the moisture content of the Geliflower is lower than 5%. After vacuum packaging, place it in the refrigerator at -35°C for 2 hours, then use a traditional Chinese medicine grinder to crush it to 20-60 mesh, and ensure that the temperature is not higher than 40°C during the crushing process;

[0041]Step 2) Put the crushed agaricus powder into a 40-60 mesh sieve and sieve, and store the sifted agaricus powder in a brown desiccator with a desiccant for later use;

[0042] Step 3) Weigh 3.0000g of Agaricus powder and the same amount of 200-300 mesh silica gel and mix evenly, place in the extraction kettle of ASI supercritical extraction instrument, and carry out CO 2 Supercritical extraction, the extraction pressur...

Abstract

The invention discloses a CO2 supercritical extraction method of gelidium amansii polyphenol and application of the gelidium amansii polyphenol. Specifically, the invention discloses the CO2 supercritical extraction method of gelidium amansii polyphenol extract; the CO2 supercritical extraction method specifically comprises the following steps: washing, drying in vacuum, crushing, carrying out CO2supercritical extraction, carrying out macroporous resin purification and freezing and drying. The CO2 supercritical extraction technology of the gelidium amansii polyphenol has the advantages of simplicity in operation, good selectivity, no harmful solvent residues, high extraction efficiency and high purity of an extracted polyphenol product; the CO2 supercritical extraction technology can be used for effectively preventing gelidium amansii polyphenol components from being oxidized; CO2 supercritical extraction is a method suitable for extracting the health-care gelidium amansii polyphenol.The gelidium amansii polyphenol extract can be used for preparing an antioxidant and also can be used for inhibiting the activity of alpha-glucosidase and alpha-amylase; the gelidium amansii polyphenol extract can be applied to medicines, health-care products and foods for lowering blood glucose.

Description

technical field [0001] The invention relates to the field of deep processing and comprehensive utilization of seaweed products. Specifically involving a CO 2 A method for supercritically extracting polyphenols from agaricus and the use of the polyphenols in agaricus. Background technique [0002] Glycyrrhizae belongs to the Rhodophyta Glycophyllaceae, also known as chicken feathers, horned vegetables, frozen vegetables, etc., and is widely distributed in coastal areas of my country. As a kind of medicinal seaweed, agaricus mainly contains various chemical components such as phenols, flavonoids, polysaccharides, minerals, etc. Agaricus can clear lungs and reduce phlegm, clear heat and dampness, nourish yin and reduce fire, cool blood and stop bleeding. And have the effect of relieving summer heat. In particular, the alginate substances contained in it have the effect of lowering blood pressure, and the starch sulfates contained in it are polysaccharides, which have the fun...
