Abstract

The invention belongs to the chemical field of natural products and particularly relates to a preparation method and use of moringa oleifera leaf polysaccharides. The preparation method comprises the steps of carrying out combined microwave-ultrasound extraction, hydrochloric acid method deproteinization, hydrogen peroxide method decoloration and AB-8 macroporous adsorption resin column separation, so as to prepare the moringa oleifera leaf polysaccharides. The preparation method of the moringa oleifera leaf polysaccharides has the advantages of short extraction time, low extraction temperature, low energy consumption and high extraction rate and purity. Besides, an animal experiment proves that the prepared moringa oleifera leaf polysaccharides have remarkable treatment effect to hyperuricosuria; by decreasing the content of cholesterol, triacylglycerol, urea nitrogen, creatinine and xanthine oxidase, the production of uric acid is achieved; meanwhile, by directly decomposing uric acid, renal functions are improved, the excretion of uric acid is promoted, and blood vessels are protected, thereby being favorable to the recovery of patients with the hyperuricosuria. The preparation method has a wide medical application prospect.

Description

technical field [0001] The invention belongs to the field of natural product chemistry, and in particular relates to a preparation method and application of Moringa oleifera leaf polysaccharide. Background technique [0002] Moringa oleifera (Moringa oleifera Lam.) is a plant of the genus Moringa in the Moringaceae family. It is a perennial tropical deciduous tree widely planted in tropical and subtropical regions of Asia and Africa, and has strong adaptability to soil conditions and rainfall. It is also cultivated in Guangdong, Taiwan and other places in my country. Moringa can be used for viewing, and its roots, leaves and tender fruits are edible; its seeds can be squeezed for oil, with an oil content of about 30%, which has high economic value. It has been found through research that, in addition to rich nutritional value, Moringa also exhibits good activities in anti-oxidation, hypoglycemic, hypolipidemic, and antifungal aspects, and the polysaccharides and polysacchari...
