[0022] The present invention also provides the preparation method of the above-mentioned eye drops, specifically:
[0023] In the first step, the components of each raw drug are mixed by weight to obtain a mixture, which is extracted 3 to 5 times with ethanol having an alcohol concentration of 80% to 90% by reflux, filtered, combined with the filtrates, and concentrated under reduced pressure to a relative density of 1.20 ~1.23 (60°C) paste, the amount of ethanol added each time is 2 to 4 times the mass of the mixture, then dried, and pulverized into powder, and the pulverized powder is added 3 to 5 times its mass. Amount of water to dissolve, add 5% to 10% sodium hydroxide relative to the mass of the powder to help dissolve under stirring, adjust the pH to 7 to 8, filter, add 10% sulfuric acid to adjust the pH to 3 to 4, stand at 2 ~4 hours, filtered, the filtrate was concentrated under reduced pressure into a paste with a relative density of 1.29-1.32 (70°C), dried, and pulv...
