Embodiment 1

[0058] Combined extraction of ginseng and schisandra, the extraction steps are as follows:

[0059] Add water to the medicinal material, adjust the pH to 9, decoct three times, 30 minutes each time, combine the extracts and concentrate; successively use 75% ethanol and 85% ethanol to refrigerate and precipitate, filter, and recover ethanol under reduced pressure until the relative density is 1.1-1.20 , the product obtained is a composite extract.

[0060] Ophiopogon japonicus is extracted separately, and the extraction steps are as follows:

[0061] Take the medicinal material and extract it once with 80% ethanol for 30 minutes each time. After filtering, add water to the filter residue and decoct for extraction twice, each time for 1 hour. The extract is ultrafiltered with an ultrafiltration membrane with a cut-off molecular weight of 30,000, and the effluent is collected. , concentrated under reduced pressure, the product obtained is a single extract, and the above combined...

Embodiment 2

[0063] Combined extraction of ginseng and schisandra, the extraction steps are as follows:

[0064] Add water to the medicinal material, adjust the pH to 14, decoct three times, 1 hour each time, combine the extracts and concentrate; successively refrigerate and precipitate with 75% ethanol and 85% ethanol, filter, and recover ethanol under reduced pressure until the relative density is 1.1-1.20 , the product obtained is a composite extract.

[0065] Ophiopogon japonicus is extracted separately, and the extraction steps are as follows:

[0066] Take the medicinal material and extract it with 95% ethanol for 3 times, each time for 1 hour. After filtering, add water to the filter residue and decoct for 3 times, each time for 2 hours. The extract is ultrafiltered with an ultrafiltration membrane with a molecular weight cut-off of 100,000, and the effluent is collected. , concentrated under reduced pressure, the product obtained is a single extract,

[0067] The combination of t...

Embodiment 3

[0069] Combined extraction of ginseng and schisandra, the extraction steps are as follows:

[0070] Add water to the medicinal material, adjust the pH to 12, decoct three times, 1 hour each time, combine the extracts and concentrate; successively use 75% ethanol and 85% ethanol to refrigerate and precipitate, filter, and recover ethanol under reduced pressure until the relative density is 1.1-1.20 , the product obtained is a composite extract.

[0071] Ophiopogon japonicus is extracted separately, and the extraction steps are as follows:

[0072] Take the medicinal material and extract it twice with 90% ethanol for 1 hour each time. After filtering, add water to the filter residue and decoct it for 3 times, 2 hours each time. The extract is ultrafiltered with an ultrafiltration membrane with a cut-off molecular weight of 60,000, and the effluent is collected. , concentrated under reduced pressure, the product obtained is a single extract,
