Bamboo leaf extract preparing method

Abstract

The invention discloses a bamboo leaf extract preparing method. The bamboo leaf extract preparing method takes fresh bamboo leaves, deionized water and cellulase as the raw materials and comprises drying and smashing the fresh bamboo leaves; adding the deionized water and the cellulase into the smashed and dried bamboo leaves, and then uniformly stirring the mixture; heating the uniformly-stirredmixture at a constant temperature; filtering the mixture to obtain filter liquor, and performing decompressed distillation on the filter liquor to obtain creamy extract; drying the creamy extract to obtain a finished product. According to the bamboo leaf extract preparing method, the cellulase can decompose cellulose between cell walls and intercellular substance to accelerate diffusion of effective constituents in the protoplasts of cells as well as to increase the separating speed and quantity of the effective constituents of the bamboo leaves, thereby increasing the extracting efficiency and rate. The bamboo leaf extract preparing method has the advantage of being high in extracting efficiency and rate.

Description

technical field [0001] The invention relates to the technical field of bamboo leaf extract, in particular to a preparation method of bamboo leaf extract. Background technique [0002] Bamboo leaves are narrowly lanceolate, 7.5-16 cm long, 1-2 cm wide, apex acuminate, base blunt, petiole about 5 mm long, one side of the edge is smooth, the other side is small serrated and rough; Parallel veins, 6-8 pairs of secondary veins, very prominent small transverse veins; leaf surface dark green, glabrous, backside lighter, base with microhairs; texture thin and brittle. Gas weak, tasteless. It is better to be green, complete and without branches. Bamboo leaves are the leaves of grasses such as Bamboo. Distributed in Shandong, Henan and south of the Yangtze River Basin. It has the effects of clearing heat and relieving restlessness, promoting body fluid and diuresis. For fever and polydipsia, infantile convulsions and epilepsy, cough and vomiting, short red urine, aphthous tongue ...

Problems solved by technology

Because the diffusion of active ingredients in cell protoplasts needs to overcome the double resistance of cell wall and interstitial cells, the precipitation of active ingredients in bamboo leaves is slow and the amount of pre...
