Abstract

The invention relates to a method for extracting total flavonoid from indocalamus. The method is characterized by comprising the following steps: a, crushing the cleaned and dried indocalamus, then sieving, and collecting fine powder to obtain indocalamus powder; b, extracting the indocalamus powder by using a polyethylene glycol-potassium chloride composite solution; c, filtering an extracted mixture, and collecting a filtrate to obtain an indocalamus total flavonoid extract. The method for extracting the total flavonoid from the indocalamus, provided by the invention, can be applied to preparation of food and medicines, so that the purpose of making full use of indocalamus resources is achieved.

Description

technical field [0001] The invention relates to a method for extracting total flavonoids from bamboo.
