Embodiment 1

[0024] Take 699g of coriander, 1398g of apricot leaves, 699g of sorrel, and 209g of scorpion grass, and add them to CO 2 In the supercritical extractor, ethanol is used as an entrainer, and the volume percentage of the entrainer to the total extraction solvent is 5%, the extraction pressure is 25MPa, the temperature is 40°C, and the CO 2 The flow rate is 2ml / g crude drug·min, the extraction time is 900min, and the supercritical extract is obtained. The supercritical extract is added to starch and 70% ethanol to make granules, dried, and pressed into tablets to make 500 tablets, each weighing 0.30g.

[0025] After testing, the content of oleanolic acid in the finished product is 6.45mg / tablet.

Embodiment 2

[0027] Take 699g of coriander, 1398g of apricot leaves, 699g of sorrel, and 209g of scorpion grass, and add them to CO 2 In a supercritical extractor, ethanol is used as an entrainer, and the entrainer accounts for 4% by volume of the total extraction solvent. The extraction pressure is 15MPa, the temperature is 30°C, and the CO 2 The flow rate is 1ml / g crude drug·min, the extraction time is 1000min, and the supercritical extract is obtained. The supercritical extract is added to starch and 70% ethanol to make granules, dried, and pressed into tablets to make 500 tablets, each weighing 0.30g.

[0028] After testing, the content of oleanolic acid in the finished product is 4.98mg / tablet.

Embodiment 3

[0030] Take 699g of coriander, 1398g of apricot leaves, 699g of sorrel, and 209g of scorpion grass, and add them to CO 2 In the supercritical extractor, ethanol is used as an entrainer, and the volume percentage of the entrainer in the total extraction solvent is 6%, the extraction pressure is 30MPa, the temperature is 60°C, and the CO 2 The flow rate is 3ml / g crude drug·min, the extraction time is 800min, and the supercritical extract is obtained. The supercritical extract is added to starch and 70% ethanol to make granules, dried, and pressed into tablets to make 500 tablets, each weighing 0.30g.

[0031] After testing, the content of oleanolic acid in the finished product is 3.22mg / tablet.
