Abstract

The invention discloses a method for extracting and separating high-purity phlorizin from Cynomorium songaricum. The method comprises the following steps: (1) smashing dry Cynomorium songaricum for later use; (2) adding water, and filtering to obtain filtrate after extraction; (3) treating the obtained filtrate with a D101 macroporous adsorption resin exchange resin, eluting with an eluting liquid, collecting and concentrating the eluant; (4) repeatedly extracting the concentrated eluant, and then, concentrating supernatant extract liquor, thus obtaining a crude phlorizin product; (5) dissolving the crude phlorizin product with ethyl acetate, adding weakly acidic activated carbon, filtering while hot, cooling and crystallizing to obtain crude phlorizin crystals; (6) adding ethyl acetate into the crude phlorizin crystals, concentrating and cooling the crystals to obtain the phlorizin product. According to the method, requirements on environment condition are not high in the whole separation process, separation time is relatively short, and purity is very high. Separation materials are easy to obtain and cheap, and operation process of separation is simple and easy to control; the ethyl acetate is used for crystallization and recrystallization, so that purification efficiency is high; the reagents used are non-toxic.

Description

[0001] technical field [0002] The invention is specifically a method for extracting and separating high-purity phlorizin from Cynomorium cynomorium. Background technique [0003] Phlorizin belongs to plant polyphenolic compounds. There are many studies abroad on the physiological functions of phloridizin. Phlorizin can reduce fire, among which cellular protein kinase can inhibit disordered proliferation of cells, and is an anti-mutagenic factor, which can be used as adjuvant therapy for skin liver cancer and other tumors. Correlation studies on the content of phloridizin show that phloridizin can effectively slow down the proliferation and growth of colon cancer cell nuclei and liver tumor cells; it has strong antioxidant properties, and the antioxidant concentration of oil is between 10-30ppm; It has a significant antihypertensive and lipid-lowering effect, and is known as a "natural antihypertensive drug". It is especially suitable for patients with hypertension or hyp...
