Embodiment 1

[0015] The preparation method of the liquid extract of the present invention is to take Xihuang herbal medicinal material, crush it into coarse powder, extract 10 times the amount of 60% ethanol, extract 3 times at 70 ° C, each time for 3 hours, filter, combine the filtrate, decolorize with activated carbon, and concentrate to relative density 1.08 (measured at 60°C), that is, Xihuangcaoliu extract.

[0016] The implementation effect is to obtain Xihuangcao fluid extract with slightly bitter taste, dark brown-black, fluidity, dry extract extraction rate from 13%, and 1g of Xihuangcao medicinal material per ml.

Embodiment 2

[0018] The preparation method of the liquid extract of the present invention is to take Xihuang herbal medicinal material, grind it into coarse powder, extract 8 times of 80% ethanol, extract twice at 85°C, each time for 2h, filter, combine the filtrate, decolorize with activated carbon, and concentrate to relative density 1.10 (measured at 60°C), that is, Xihuangcaoliu extract.

[0019] The implementation effect is to produce Xihuangcao fluid extract with slightly bitter taste, dark brown-black, fluidity, dry extract extraction rate from 16%, and 1g of Xihuangcao medicinal material per ml. In the preparation of the liquid extract by alcohol extraction, the number of times of extraction and the amount of alcohol used in this method are relatively small, and the extraction rate of the dry extract is relatively high, which reduces the cost while ensuring the extraction of effective substances.

Embodiment 3

[0021] The preparation method of the liquid extract of the present invention is to take Xihuang herbal medicinal material, grind it into coarse powder, extract 5 times of 95% ethanol, extract twice at 70 ° C, each time for 1 hour, filter, combine the filtrate, decolorize with activated carbon, and concentrate to relative density 1.00 (measured at 60°C).

[0022] The effect of implementation is to obtain Xihuangcao fluid extract with slightly bitter taste, dark brown black, fluidity, dry extract extraction rate from 12%, and 1g of Xihuangcao medicinal material per ml.
