Embodiment 1
[0021] Embodiment 1: Preparation of total flavonoids of Tianjihuang
[0022] Take an appropriate amount of Tianjihuang medicinal material, cut into sections, decoct three times with 12 times, 10 times, and 8 times the amount of water, each time for 1 hour, filter, combine the filtrates, and concentrate under reduced pressure to contain Tianjihuang medicinal material 0.5g / ml Add it to the pre-prepared polyamide column, first elute with distilled water until the color of the eluent is light, then add 60% ethanol for elution until the hydrochloric acid-magnesium powder reaction is negative, collect the alcohol lotion, concentrate to a relatively The concentrated solution with a density of 1.08-1.10 (60°C) is spray-dried under the conditions of an inlet air temperature of 100-200°C and an outlet air temperature of 50-150°C to obtain the total flavonoids of Tianjihuang. According to the above method, five batches of Tianjihuang medicinal materials were selected for extraction, and ...
Embodiment 2
[0027] Example 2: The effect of total flavonoids of Tianjihuang on liver fibrosis in rats caused by common bile duct ligation
[0028] 1. Experimental animals:
[0029] SD rats, SPF grade, half male and half male, provided by Guangdong Medical Experimental Animal Center, animal qualification certificate number: SCXK (Guangdong) 2008-0002.
[0030] Drug grouping and handling:
[0031] Normal control group: distilled water.
[0032] Model control group: the rat liver fibrosis model was induced by common bile duct ligation, and an equal volume of distilled water was given.
[0033] Low-dose group of total flavonoids of Tianjihuang: before the experiment, take total flavonoids of Tianjihuang (total flavonoid content is 63.5%), add distilled water to prepare a suspension with a concentration of 0.9 mg / ml.
[0034] Medium-dose group of total flavonoids of Tianjihuang: before the experiment, take total flavonoids of Tianjihuang (total flavonoids content is 63.5%), add distil...

[0066] , Drug grouping and processing:
[0067] Normal control group: distilled water.
[0068] Model control group: the rat immune liver fibrosis model induced by pig serum was used, and an equal volume of distilled water was given.
[0069] Low-dose group of total flavonoids of Tianjihuang: before the experiment, take total flavonoids of Tianjihuang (total flavonoid content is 63.5%), add distilled water to prepare a suspension with a concentration of 0.9 mg / ml.
[0070] Medium-dose group of total flavonoids of Tianjihuang: before the experiment, take total flavonoids of Tianjihuang (total flavonoids content is 63.5%), add distilled wate...
