Abstract

The invention relates to a method for extracting total flavone from reed leaves. The method includes the following steps that the reed leaves after being cleaned and dried are smashed and then sieved, fine powder is collected, and reed leaf powder is obtained; the reed leaf powder is extracted with a polyethylene glycol-potassium chloride composite solution; the extracted mixture is filtered, filtered liquid is collected, and reed-leaf total-flavone extract is obtained. According to the method, the polyethylene glycol-potassium chloride composite solution firstly serves as an extracting medium, and the reed-leaf total flavone is extracted in cooperation with the microwave-assistant method at the high temperature and the high pressure; transmission of microwave energy can be accelerated through potassium chloride, fracturing of cells is quickened to promote releasing of the total flavone; the water-soluble flavone and the fat-soluble flavone in the reed leaves can be simultaneously extracted through a composite polyethylene-glycol solution. By means of the method for extracting the total flavone from the reed leaves, the extracting rate of the reed-leaf total flavone can be increased, the extracting time is shortened, the preparing cost is reduced, the environment is friendly, and following separating and purifying of the reed-leaf total flavone are facilitated.

Description

technical field [0001] The invention relates to the technical field of effective active ingredients of natural plants, in particular to a method for extracting total flavonoids from leaves of zongzi. Background technique [0002] Zongye is the leaves of Ruozhu, which belongs to the Poaceae family and the genus Ruozhu, which contains more than 20 species, which are mainly distributed in the provinces and regions south of the Yangtze River in my country. Zongye is mainly used in food packaging to wrap zongzi. Zongye is recognized by the Ministry of Health as a dual-use resource for medicine and food, and is a new type of edible and medicinal resource that can be developed and utilized. Modern drug analysis studies have shown that Zongye contains Zongye flavonoids, Zongye polysaccharides, organic selenium, zinc, iodine, calcium, multivitamins and amino acids, etc., which are beneficial to the human body. The flavonoids and ginkgo flavonoids have similar chemical composition, ...
