Abstract

The invention discloses polysaccharides from the rhizomes of Ambrosia polysaccharides, a preparation method thereof and an anti-oxidation application. The inventors obtained the rhizome polysaccharide AVRP-1 of A. versicolor by extracting the crude polysaccharide from the rhizome of A. radix A. radix, and then purifying it by Sephadex column chromatography. AVRP‑1 has antioxidant activity against DPPH and the half effective concentration of hydroxyl radicals (EC 50 ) are 4.50 mg / mL and 2.47 mg / mL respectively, which are expected to be used to develop into functional food and health medicine, and can also make full use of Yangchun sand, which will help turn waste into treasure, improve the overall economic value of Yangchun sand, and benefit increase income.

Description

technical field [0001] The invention relates to a natural product, a preparation method and application thereof, in particular to a polysaccharide from the rhizome of Dionysus polysaccharides with antioxidative effect, a preparation method and application thereof. Background technique [0002] Amomum amomum Amomum villosum Lour., green shell sand Amomum villosum Lour.var xanthioides T.L. Wu et Senjen or Hainan Sand Amomum longiligular Dried ripe fruit of T.L. Wu. It has the effects of dispelling dampness and appetizing, warming the spleen and stopping diarrhea, regulating qi and preventing miscarriage. Used for dampness and turbidity resistance, abdominal distension without hunger, spleen and stomach deficiency and cold, vomiting and diarrhea, pregnancy nausea, fetal movement disturbance. Among them, Yangchun amomum is the main source of amomum, which is a medicinal material with the same origin as medicine and food, and has a large demand. Most of the medicinal ...
