The extracts of *Trifolium repens* obtained by existing reflux extraction methods have low contents of effective components such as saponins and flavonoids, making it difficult to prepare anhydrous swallowable formulations.
Solvent soaking and percolation extraction methods were adopted. The crude powder of *Trifolium repens* rhizome was soaked and percolated with an ethanol aqueous solution. The temperature and solvent flow rate were controlled to reduce the extraction of impurities such as starch and polysaccharides, and to increase the concentration difference of effective components to enhance the dissolution effect.
It significantly increases the content of saponins and flavonoids in *Trifolium repens* extract and reduces the content of impurities, making it suitable for preparing anhydrous swallowable granules for convenient consumption and carrying.

The method comprises the following steps: firstly, soaking the Radix Ternatae in a solvent to form a saturated solution; and then, slowly discharging the saturated solution from the lower outlet and adding fresh solvent from the upper part in the percolation extraction process, so that the concentration difference is formed on the inside and outside of the plant cell wall, which is beneficial to the dissolution of effective components (such as saponins and flavonoids). The dynamic percolation extraction method can extract the effective components completely due to the concentration difference, and the impurities (such as starch and polysaccharides) which are not dissolved in the solvent are basically not extracted. The Radix Ternatae contains a large amount of starch, polysaccharides and other components. The percolation extraction method of the application can effectively reduce the starch, polysaccharides and other impurities in the extract. The extract obtained by the percolation extraction method has a lower extract yield (about 1 / 3 or 1 / 4) than the reflux extraction, but the content of effective components such as saponins and flavonoids is higher than that of the conventional reflux extraction (the effective components of the percolation extraction are usually more than twice of the conventional reflux extraction).

[0026] In the application, the solvent is preferably an ethanol aqueous solution; and the volume content of ethanol in the ethanol aqueous solution is preferably 50%-80%, more preferably 60%-70%.
[0027] In the soaking process, the amount of the solvent is preferably 2-4 mL, more preferably 2-3 mL, based on 1 g of the Radix Ternatae coarse powder, and the liquid surface of the Radix Ternatae coarse powder is immersed in the solvent by 1-2 cm; the soaking temperature is preferably 40-60°C, more preferably 50°C; and the soaking time is preferably 5-24 h, more preferably 10-20 h.
[0028] In the process of the present application, the amount of solvent is preferably 6-10 mL, based on 1 g of the rootstock powder of Radix et Rhizoma Gromwell; the present application uses less solvent (1 / 2 or 1 / 3 of the amount used in conventional reflux extraction); the dripping speed of the lower outlet of the percolation extractor is preferably 1-1.8 times the volume per hour, more preferably 1.5 times the volume per hour; the present application controls the dripping speed of the lower outlet to regulate the speed of the whole percolation extraction; the percolation extraction time is preferably ≥4 h, more preferably 4-5 h; and the percolation extraction temperature is preferably 40-60°C, more preferably 50°C.
[0029] In the present application, the soaking and percolation extraction temperatures are both 40-60°C, which is much lower than the reflux extraction temperature (above 100°C), so that the heat-sensitive effective components are not destroyed and the activity of the effective components can be maintained.

[0133] Test Example 1 In vivo exploration test of three-leafed green ginseng percolation extract against H1N1 influenza virus
[0134] To investigate the anti-viral effect of Tripterygium wilfordii Hook. f. extract on influenza virus (H1N1) infected mice in vivo by the model of mice infected with virus by nose drop, and to provide basic data for its clinical application. According to the body weight, the animals were randomly and equally divided into 6 groups, namely, negative control group, model control group, oseltamivir phosphate capsule group, Lianhuaqingwen capsule group, low-dose Tripterygium wilfordii Hook. f. extract group (0.78 g crude drug / kg), and high-dose Tripterygium wilfordii Hook. f. extract group (1.56 g crude drug / kg). The equivalent of 1 and 2 times of the clinical dose was calculated according to the body surface area. There were 20 animals in each group, half of them were male and half of them were female. After grouping, the animals in each group were modeled, administered, and the death of animals was recorded according to the experimental design. The test results are discussed as follows:
[0135] The test results of animals in each group showed that after viral infection, the animals in the model control group began to show loose hair, weight loss, and death from D7 after infection. By D11, the mortality rate of the model control group was 70% (14 / 20), and the average survival time was 10 days. The mortality rate of the oseltamivir phosphate capsule group was 30% (6 / 20), the death protection rate was 40%, and the average survival time was significantly prolonged to 13 days. The mortality rate of the Lianhuaqingwen capsule group was 65% (13 / 20), the death protection rate was 5%, and the average survival time was 11 days. The mortality rate of the low-dose Tripterygium wilfordii Hook. f. extract group was 50% (10 / 20), the death protection rate was 20%, and the average survival time was 11 days. The mortality rate of the high-dose Tripterygium wilfordii Hook. f. extract group was 30% (6 / 20), the death protection rate was 40%, and the average survival time was significantly prolonged to 12 days, which showed obvious death protection effect on influenza infected mice (Table 1).
[0136] The results of gross observation of the lungs of animals showed that the mice in the model control group showed lung tissue congestion, edema, volume increase, and necrosis. Compared with the negative control group, the body weight of the animals in the model control group was significantly reduced, and the lung index was significantly increased, indicating that the influenza virus infected mouse model was successful. The lung index of the animals in the high-dose Tripterygium wilfordii Hook. f. extract group was significantly lower than that of the model control group, and the lung index inhibition rate was 27.20%, which showed good protection effect on viral pneumonia in infected mice. There was no significant difference in the lung index of the animals in the other groups compared with the model control group (Table 2).
