Embodiment 1
[0059] 1) Extraction: The whole plant of Andrographis paniculata was dried at 60°C for 5 hours to obtain the dried whole plant of Andrographis paniculata. Take 5Kg of dried whole herb of Andrographis paniculata, add 6 times the weight of the medicinal material in an ethanol aqueous solution containing 95% ethanol mass percentage (that is, ethanol aqueous solution 30Kg), and extract at 90°C under reflux, and the time of each extraction is 3h, and the total extraction 3 times (a total of 90Kg in ethanol aqueous solution), and combine the extracts;
[0060] 2) Extraction: Concentrate the extract obtained in step 1) to nearly dryness under reduced pressure to obtain 450g of thick extract, add 1Kg of water to dissolve, and then use 0.65Kg of petroleum ether with a boiling point of 60°C to 90°C each time for extraction and co-extraction 3 times, the extract was collected, and the extract was concentrated to obtain 200 g of the effective fraction of Andrographis paniculata.

Embodiment 2
[0065] 1) Extraction: The whole plant of Andrographis paniculata was dried at 60°C for 5 hours to obtain the dried whole plant of Andrographis paniculata. Take 5Kg of dried whole herb of Andrographis paniculata, add 10 times the weight of the medicinal material in an ethanol aqueous solution containing 95% ethanol by mass (i.e. 50Kg of ethanol aqueous solution), and extract at 100°C under reflux. The time of each extraction is 2h, and the total extraction 2 times (a total of 100Kg in ethanol aqueous solution), combined extracts;
[0066] 2) Extraction: Concentrate the extract obtained in step 1) to nearly dryness under reduced pressure to obtain 440g of thick extract, add 0.5Kg of water to dissolve, and then use 0.35Kg of petroleum ether with a boiling point of 60°C to 90°C each time for extraction. Extract 3 times, collect the extract, and concentrate the extract to obtain 180 g of the effective fraction of Andrographis paniculata.

Embodiment 3
[0071] 1) Extraction: The whole plant of Andrographis paniculata was dried at 60°C for 5 hours to obtain the dried whole plant of Andrographis paniculata. Take 5Kg of dried whole herb of Andrographis paniculata, add an ethanol aqueous solution containing 95% ethanol mass percentage (that is, ethanol aqueous solution 40Kg) that is 8 times the weight of the medicinal material each time, and extract under reflux at 90°C. The time of each extraction is 3h, and the total extraction 3 times (a total of 120Kg in ethanol aqueous solution), combined extracts;
[0072] 2) Extraction: Concentrate the extract obtained in step 1) to nearly dryness under reduced pressure to obtain 470g of thick extract, add 2Kg of water to dissolve, and then use 0.8Kg of petroleum ether with a boiling point of 60°C to 90°C each time for extraction and co-extraction 3 times, the extract was collected, and the extract was concentrated to obtain 220 g of the effective fraction of Andrographis paniculata.
