Embodiment 1
[0013] Take the coarse powder of Astragalus membranaceus, heat and reflux with an appropriate amount of 50% ethanol to extract the medicinal materials, cool the extract overnight and filter, concentrate the filtrate on D101 macroporous adsorption resin, rinse with water first, then rinse with 30% to 70% ethanol, and absorb Concentrated and freeze-dried. The extract was detected by HPLC-ELSD method, the analysis condition was Agilent Extend-C18, and the mobile phase was H2O-CH 3 CN, the aqueous phase decreased linearly from 70% to 10% within 30min; ELSD parameters: drift tube temperature 105°C, carrier gas flow rate 2.7L / min; Saponin I is the detection component, and its content is determined by external standard method. Wherein the contents of astragaloside I, II and IV are 33%, 17% and 15% respectively, the content of isoastragloside II is 1%, and the content of acetylastragaloside I is 5%.

Embodiment 2
[0015] Example 2 Antitumor effect experiment of composition 1 (total alkaloids of matrine: total saponins of astragalus = 1:2)
[0016] The mice pre-inoculated with H22 ascites tumor were sacrificed, and 1ml of ascites tumor was extracted from the abdominal cavity, and diluted with normal saline to 1×10 6 cells / ml, injected into the underarm of ICR female mice at 0.2ml / only, and after 24 hours, they were randomly divided into groups and started to administer. The compositions were administered in high, medium and low doses respectively. After 8 days of continuous administration, the drug was stopped, the mice were weighed, and the tumor pieces were dissected and weighed separately for statistical analysis. See Table 1 for the results.

Embodiment 3
[0019] Example 3 Synergistic experiment of composition 2 (total alkaloids of matrine: total saponins of astragalus=1:3) and chemotherapeutic drugs
[0020] The mice pre-inoculated with H22 ascites tumor were sacrificed, and 1ml of ascites tumor was extracted from the abdominal cavity, and diluted with normal saline to 1×10 6 cells / ml, injected into the underarm of ICR female mice at 0.2ml / only, and after 24 hours, they were randomly divided into groups and started to administer. The dosage of the chemotherapeutic drug cyclophosphamide is 20 mg / Kg, intramuscular injection, and administered every other day; the dosage of cisplatin is 1 mg / Kg, intraperitoneal injection, and daily administration. The composition was intragastrically administered at a dose of 360 mg / Kg, once a day, and the results are shown in Table 2.
