Common-sage-herb general flavone extracting method and method for preparing general-flavone solid beverage

Abstract

The invention discloses a common-sage-herb general flavone extracting method. The common-sage-herb general flavone extracting method includes the following steps that (1) fresh common sage herbs are selected as raw materials, and drying, smashing and screening are conduced; (2) the obtained common sage herbs are soaked in ethyl alcohol, and are subjected to ultrasonic treatment; (3) extracting isconducted, and common-sage-herb crude extracting liquid is obtained; (4) adsorption resin is prepared; (5) the resin adsorbs the common-sage-herb crude extracting liquid; (6) elution and drying are conducted to obtain common-sage-herb general flavone; (7) a standard curve is drawn, and the average content of the general flavone of samples is calculated; (8) the antioxidant capacity of the generalflavone is measured. The common-sage-herb general flavone extracting method has the advantages that an operating method is simple, the extracting content of the common-sage-herb general flavone is increased, and the quality (comprising the high purity and good solubility and dispersity) is greatly improved; a solid beverage is prepared with the common-sage-herb general flavone, and the economic value of the common sage herbs can be improved.

Description

technical field [0001] The invention belongs to the technical field of extracting active ingredients from natural medicinal plants, and in particular relates to a method for extracting total flavonoids from lychee grass and preparing a solid beverage of the total flavonoids.
