Embodiment 1

[0018] A method for improving icariin in epimedium raw materials by high temperature and high pressure method, comprising the following steps:

[0019] S1, selecting and removing impurities in the picked fresh Epimedium sagittatum, and removing other impurities therein;

[0020] S2. After the Epimedium raw material in S1 is crushed into fragments with a diameter of no more than 2cm, put it into a high-pressure extraction tank, and the loading amount must not exceed 2 / 3 of the extraction tank. Then, under high temperature and high pressure, open the bottom steam valve, and Enter steam, when the temperature in the tank reaches 110°C and the pressure in the tank is 0.08MPa, process for 4 hours to obtain Epimedium with high content of icariin;

[0021] The icariin detection method provided in the 2015 edition of "Chinese Pharmacopoeia" was used to detect the epimedium with high content of icariin in this example, and the test result showed that the content of icariin in epimedium ...

Abstract

The invention discloses a method for improving icariin in a herba epimedii raw material by a high-temperature high-pressure method, and particularly belongs to the technical field of traditional Chinese medicinal material processing. The method comprises the following steps of: taking the herba epimedii raw material, and after the herba epimedii raw material is smashed, carrying out high-temperature high-pressure processing to obtain herba epimedii with a high icariin content, wherein a high temperature is 110-130 DEG C, and high pressure is 0.08-0.1 MPa. The invention also provides application of the method for improving the icariin in the herba epimedii raw material by the high-temperature high-pressure method in the improvement of the icariin in the herba epimedii raw material. Epimedium sagittatum (Sieb. et Zucc.) Maxim. raw materials from the Qinling Daba Mountain are sorted and smashed, through a high-temperature high-pressure processing method, the icariin in the Epimedium sagittatum (Sieb. et Zucc.) Maxim. raw materials can be improved to 0.76%, raw materials can be conveniently used while the quality of the epimedium sagittatum (Sieb. et Zucc.) Maxim. raw materials is improved.

Description

technical field [0001] The invention belongs to the technical field of processing traditional Chinese medicinal materials, and in particular relates to a method for increasing icariin in epimedium raw materials by a high-temperature and high-pressure method and an application thereof. Background technique [0002] Epimedium sagittata, recorded in "Chinese Pharmacopoeia" 2015 edition, page 327, is the dried leaf of Epimedium sagittatum, a plant of the family Berberidaceae. rheumatism. The main components in Epimedium are mainly flavonoids, and the components with higher content are icariin, epimedin c, icariin and epimedin, etc. The traditional wild harvesting is dried in the shade. Or the appearance color of the dried raw materials is dark and dark, and the content of icariin in the raw materials of Epimedium from different origins is quite different. [0003] Judging from several major producing areas in China, Gansu has the highest raw material content of Epimedium heart...
