Problems solved by technology

[0004] On the basis of screening more than 600 kinds of traditional Chinese medicines, we accidentally found that the extract of the wood butterfly can treat cataracts. Although it has been reported in the literature that the wood butterfly has a certain effect on the treatment of cataracts in the compound and alone, it has not been found that the wood butterfly extract can treat cataracts. Active ingredients for treating cataracts

Embodiment 1

[0053] Embodiment 1: the preparation method of Chinese medicinal wood butterfly total flavonoid extract

[0054] Take traditional Chinese medicine wood butterfly, add 10 times the amount of 40% ethanol, soak at room temperature for 2 hours, then heat to 80 ~ 100 ° C for reflux extraction for 2 hours, separate the first extract, and then add 8 times the amount of 50% ethanol, heat to 80 ~ 100 ℃ reflux extraction for 1.5 hours, and separate the second extract. The two extracts were combined, and the solid impurities in the extract were removed by filtration. The extracting solution is recovered with solvent and dried to obtain 40% ethanol extract of the wood butterfly. According to the following determination method, the content of total flavonoids was determined to be 30.5%, and the content of each monomer: baicalein (6.7%), baicalin (0.2%), styloside A (10.8%), styloside B (8.6%) , chrysin (3.7%), chrysin-7-O-glucuronide (0.5%).

Embodiment 2

[0061] Embodiment 2: the preparation method of Chinese medicinal wood butterfly total flavonoids extract

[0062] Basically the same as Example 1, the difference is that water is an extraction solvent, and the specific method is as follows:

[0063] Take the traditional Chinese medicine A. chinensis, add 8 times the amount of water, soak at room temperature for 2 hours, then decoct and extract for 2 hours, separate the first extract, add 4 times the amount of water, decoct and extract for 1.5 hours, and separate the second extract. The two extracts were combined, and the solid impurities in the extract were removed by filtration. The extract is recovered by solvent, and dried to obtain the water extract of Butterfly. According to the following measurement method, the total flavonoid content was determined to be 20.6%, and the content of each monomer (determination method was the same as that of Example 1): baicalein (3.4%), baicalin (0.1%), xyloside A (8.1%), Trichoside B (7...

Embodiment 3

[0064] Embodiment 3: the preparation method of Chinese medicinal wood butterfly total flavonoids extract

[0065] It is basically the same as Example 1, the difference is that 70% ethanol is the extraction solvent, and the specific method is as follows: take the traditional Chinese medicine A. After 2 hours, the first extraction solution was separated, and then 8 times the amount of 70% ethanol was heated to 80-100° C. for reflux extraction for 1.5 hours, and the second extraction solution was separated. The two extracts were combined, and the solid impurities in the extract were removed by filtration. The extracting solution is recovered with solvent and dried to obtain 70% ethanol extract of the wood butterfly. The content of total flavonoids was determined to be 43.9%, and the content of each monomer (determination method was the same as that of Example 1): baicalein (6.8%), baicalin (3.9%), xyloside A (12.1%), xyloside B ( 10.7%), chrysin (2.9%), chrysin-7-O-glucuronide ...
