Embodiment 1
[0024] Dry the silk-leaved pine grass at 30°C-60°C at low temperature, crush it and decoct it with water at a ratio of 1:10, decoct 2-3 times, each time for 1-3 hours, combine the extracts and pass through a 30-40 mesh sieve Filtrate, concentrate under reduced pressure at 40°C to 60°C to obtain a clear paste, the concentration of which is 7.8mg / ml, dry the obtained clear paste, grind it into a fine powder, and obtain the extract.
[0025] The obtained extract is added to starch, fully mixed, granulated, dried, granulated, and compressed into 50 mg tablets.
Embodiment 2
[0027] 1) Dry the silk-leaved pine grass at 30 ℃ ~ 60 ℃ at low temperature, crush it and decoct it with water at a ratio of 1:10, decoct 2 to 3 times, each time for 1 to 3 hours, combine the extracts and dry them for 30 to 40 minutes. Filter through a mesh sieve, concentrate under reduced pressure at 40° C. to 60° C. to become a clear paste; 2) carry out ethanol purification treatment on the obtained clear paste, and add concentration of 90% to 95% ethanol to the clear paste under stirring to make the clear paste The alcohol content in the mixture reaches 75%, let stand for 24 to 72 hours, take the supernatant and filter it through a 40 to 60 mesh sieve, concentrate under reduced pressure at 30°C to 50°C, and obtain a purified clear paste with a concentration of 6.9mg / ml , the purified clear paste is distilled under reduced pressure at 40°C to 60°C to remove ethanol; 3) cooling to room temperature, drying, grinding into fine powder to obtain the extract.
[0028] The obtained ...
Embodiment 3
[0030] 1) Dry the silk-leaved pine grass at 30 ℃ ~ 60 ℃ at low temperature, crush it and decoct it with water at a ratio of 1:10, decoct 2 to 3 times, each time for 1 to 3 hours, combine the extracts and dry them for 30 to 40 minutes. Filter through a mesh sieve, concentrate under reduced pressure at 40° C. to 60° C. to become a clear paste; 2) carry out ethanol purification treatment on the obtained clear paste, and add concentration of 90% to 95% ethanol to the clear paste under stirring to make the clear paste The alcohol content in the mixture reaches 70%, let it stand for 24-58 hours, take the supernatant and filter it through a 40-60 mesh sieve, concentrate under reduced pressure at 30°C-50°C, and distill it under reduced pressure at 40°C-60°C Ethanol; 3) under agitation again, add the ethanol that concentration is 90%~95% to make the alcohol content in the mixture to 85% in the described clear paste, leave standstill for 36~72 hours, take the supernatant and pass through...
