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 ...
Embodiment 2
[0023] A method for improving icariin in epimedium raw materials by high temperature and high pressure method, comprising the following steps:
[0024] S1, selecting and removing impurities in the picked fresh Epimedium sagittatum, and removing other impurities therein;
[0025] 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 120°C and the pressure in the tank is 0.09MPa, process for 3 hours to obtain Epimedium with high content of icariin;
[0026] The icariin detection method provided in the 2015 edition of "Chinese Pharmacopoeia" was used to detect the epimedium with high content of icariin obtained in this example, and the test result showed that the content of icariin in e...
Embodiment 3
[0028] A method for improving icariin in epimedium raw materials by high temperature and high pressure method, comprising the following steps:
[0029] S1, selecting and removing impurities in the picked fresh Epimedium sagittatum, and removing other impurities therein;
[0030] 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 130°C and the pressure in the tank is 0.1MPa, start timing, and process for 2 hours to obtain Epimedium with high content of icariin;
[0031] The icariin detection method provided in the 2015 edition of "Chinese Pharmacopoeia" was used to detect the epimedium with high content of icariin obtained in this example, and the test result showed that the conten...
