Embodiment 1
[0082] The preparation and assay of embodiment 1 epimedium extract
[0083] 1. Preparation of Epimedium Extract
[0084] Take 1000g of Epimedium medicinal material, crush it into medium powder, add 12 times the amount of 70% ethanol, soak for 12 hours, filter, and use the filtrate for later use; add 70% ethanol to heat and extract three times, each time for 1.5 hours, filter, and combine the filtrate , the filtrate was concentrated under reduced pressure to 1000ml, put on the treated D101 macroporous resin column, first eluted with 4L of distilled water, then eluted with 3L of 25% ethanol, and finally eluted with 15L of 70% ethanol, collected 70% ethanol for elution Liquid, recovery of ethanol under reduced pressure, vacuum drying, that is.
[0085] Three batches of Epimedium extract were prepared according to the above method, and the yields are shown in Table 5.

Embodiment 2
[0097] Preparation and content determination of embodiment 2 kudzu root extract
[0098] 1. Preparation of root extract
[0099] Take the Pueraria root medicinal material, crush it, add 70% ethanol to heat and reflux to extract twice, add 12 times the amount of alcohol for the first time, extract for 2 hours, add 10 times the amount of alcohol for the second time, extract for 1 hour, combine the extracts, filter, and filtrate Concentrate until there is no alcohol smell, filter, and elute with water and 70% ethanol respectively in the AB-8 macroporous resin that has been treated on the filtrate, and the elution volume is 4 times the volume of the column. Deliquify, recover ethanol, concentrate under reduced pressure to a relative density of 1.1-1.3 (50°C), and dry to obtain the product.
