Embodiment 1
[0035] Weigh 1 Kg of the root vegetable and put it in an extraction tank, add water and decoct three times (the amount of water added each time is 10 Kg, and the decoction time is 2 hours each time), and filter through a 100-mesh sieve to obtain the filtrate.
[0036] Send the filtrate to a three-effect energy-saving concentrator to concentrate to a clear paste with a relative density of 1.16-1.18 (measured at 60-65°C), and let it cool. The concentration temperature is 50-90°C, and the vacuum degree is -0.01 - -0.06Mpa.
[0037] Add dehydrated ethanol to the clear paste after cooling to make the alcohol content reach 60%, stir evenly, leave standstill, filter with 100 mesh sieves after 24 hours to obtain filtrate and precipitate, precipitate is washed with 6Kg60% ethanol, combine washing liquid and filtrate ( Hereinafter referred to as the mixed solution), let it stand for 4 hours.
[0038] Concentrate the mixed solution under reduced pressure to a clear paste with a relative...
Embodiment 2
[0045] The pharmaceutical composition prepared in Example 1 is carried out in animal experiments, and it is found that the pharmaceutical composition can significantly reduce CCl 4 Serum ALT of poisoned rats decreased CCl 4 The residence time of mouse serum BSP has obvious hepatoprotective effect.
Embodiment 3
[0047] The choleretic test of rats with the pharmaceutical composition prepared in Example 1 shows that it can obviously promote bile secretion and reduce total bilirubin in blood.
