Embodiment 1

[0048] Embodiment 1. water extraction extract

[0049] Pueraria japonica (Snake mushroom, Balaophora japonica Mak.) whole herb 100g, heat reflux with 500g distilled water, extract three times (500ml water / time), extract 1 hour each time, extract 26.0g water extract after concentrating under reduced pressure, dissolve In 50 ml of water, add ethanol until the alcohol content reaches 70% (volume ratio), precipitate, filter, and concentrate the filtrate to dryness to obtain 14.0 g of a yellow powdery solid.

[0050] The filtrate part is separated by macroporous resin column:

[0051] 14.0 g of the filtrate was dissolved in 50 ml of water, added to a 100 g macroporous resin column (S-8), washed with distilled water until the effluent was colorless, then eluted with ethanol until the effluent was colorless, and the ethanol eluted part was concentrated to obtain 7.5g. The macroporous resin is washed with water until the effluent is alcohol-free (macroporous resin regeneration).

Embodiment 2

[0052] Embodiment 2. Alcohol extraction extract

[0053] Take 2500g whole herb of Balaophora inovolucrata Hook f., heat reflux with 95% EtOH, extract three times (10L 95% EtOH / time), slowly heat to boiling, extract for 1 hour each time, and concentrate the extract under reduced pressure 532.0 g of 95% EtOH extract was obtained, suspended in 1500 ml of water, filtered, and the filtrate was extracted three times with ethyl acetate (1500 ml / time), the extracts were combined, and the solvent was recovered under reduced pressure to obtain 210.0 g of a yellow powdery solid.

Embodiment 3

[0054] Embodiment 3. ethyl acetate extraction extract

[0055] Multi-core snake mushroom (Balaophora polyandra Griff.) whole herb 1000g, with petroleum ether 5000ml, heated to reflux, extracted three times, each extraction for 1 hour, the extract was concentrated under reduced pressure to obtain 56.0g of petroleum ether extract; Ester 5000ml, heated to reflux, extracted three times, each time for one hour, the extracts were combined, and the solvent was recovered under reduced pressure to obtain 173.0g of ethyl acetate extraction part.

[0056] Ethyl acetate extraction part is separated by macroporous resin:

[0057] 173.0 g of the filtrate was dissolved in 1000 ml of water, filtered, and the filtrate was added to a 1000 g macroporous resin column (S-8), washed with distilled water until the effluent was colorless, then eluted with ethanol until the effluent was colorless, and ethanol was eluted Partial concentration gave 113.0 g. The macroporous resin is washed with water u...
