Abstract

The invention discloses a medicinal material processing method for improving icariin content. The processing method includes the steps: selecting; impurity removing; washing; drying; drying; steaming;drying in the shade. By the processing method, northeast epimedium crops can be prepared into medicinal materials, the icariin content in the medicinal materials is greatly improved, requirements ofChinese pharmacopoeia are met, the retention time of the medicinal materials can be prolonged by the method, and mildew spoiling of the material is prevented.

Description

technical field [0001] The invention relates to the technical field of processing Chinese medicinal materials, in particular to a processing method of medicinal materials for increasing the content of icariin. Background technique [0002] Epimedium is also known as three-branch nine-leaf grass, fairy spleen, ox horn flower, three-pointed wind, sheep horn wind, and triangle lotus. The stem is thin cylindrical, about 20cm long, the surface is yellowish green or light yellow, with luster. Cauline leaves opposite, two times and three compound leaves; leaflets oval, 3-8cm long, 2-6cm wide; apex slightly pointed, base of terminal leaflets heart-shaped, leaflets on both sides smaller, eccentric, outer Larger, ear-shaped, with yellow bristle-like fine serrations on the edge; yellow-green upper surface, gray-green lower surface, 7-9 main veins, sparse and long hairs at the base, protruding on both sides of the fine veins, and obvious network veins; small The petiole is 1-5cm long....
