Problems solved by technology

③Ursodeoxycholic acid is a commonly used drug for the treatment of fatty liver in clinical practice. It was once considered to be effective in reducing liver fat content, but its efficacy has not been confirmed by two years of randomized double-blind trials.
④Antioxidants such as reduced glutathione, silymarin, vitamin E, taurine, etc. have a certain effect of reducing enzymes and protecting the liver, participate in fat metabolism in the liver, reduce liver inflammation, promote the recovery of damaged liver cells, and help Treats fatty liver and can reduce induced fibrosis, but its exact efficacy remains to be proven

Embodiment 1

[0020] Example 1 Separation and purification of aketoside D

[0021] According to the research results of extraction process optimization, take 5.0kg of Dipsacus chuanxiong medicinal material decoction pieces, add 70% ethanol to heat and reflux to extract twice, the amount of extraction solvent is 10 times (V / W) of the raw medicinal material each time, and the extraction time is 2 times each time. hours, combined the two extracts, recovered ethanol under reduced pressure, and obtained aketoside D transfer rate of 93%. By screening the experimental results, AB-8 macroporous adsorption resin was selected as the rough step separation method to enrich the crude product of aketoside D. The AB-8 macroporous adsorption resin column was 10cm in diameter x 65cm in length, and the weight ratio of resin dosage to medicinal material It is 1:1. Dilute the above-mentioned concentrated drug solution with water to a solid content of 8%, load the sample, wash with 3 column volumes of water, r...

Embodiment 2

[0022] Example 2 Preparation of aketoside D

[0023] Test 1. Preparation of Aketoside D Injection

[0024] Prescription 1: Akebia saponin D 1000mg, solubilizer F68 20mg, cosolvent propylene glycol 60mg, antioxidant sodium sulfite 30mg. Adjust the isotonicity with anhydrous glucose, adjust the pH value to 7 with buffer salt, and add redistilled water to 150mL.

[0025] Prescription 2: Akebia saponin D 1000mg, solubilizer F68 25mg, HP-β-cyclodextrin 2000mg, antioxidant sodium sulfite 50mg. Dissolve the prescribed amount of HP-β-cyclodextrin in 40mL of ethanol at 600r.min -1 Add aketoside D powder under stirring, continue to stir for 2 hours, and set aside; take sodium bisulfite and F68 and add 50mL aqueous solution to dissolve, and inject aketoside D's HP-β-cyclodextrin ethanol solution under stirring until aketoside D was completely dissolved, then pre-frozen at -60°C, and dried in vacuum to obtain an off-white loose freeze-dried powder.

Abstract

The invention aims at providing a new application of akebiasaponin D, particularly an application of akebiasaponin D in preparing medicines and/or health products for treating and preventing fatty liver and related diseases by using akebiasaponin D as an active component, wherein, the fatty liver comprises alcoholic fatty liver and non-alcoholic fatty liver, and fatty liver and hyperlipidemia due to decreased estrogen levels, and the related diseases comprise fatty liver with lipid metabolism abnormality, hormone level disorder, fatty liver with dyslipidemia, steatohepatitis, liver cirrhosis, and the like. Studies of pharmacology, pharmaceutical effect and toxicology prove that the medicines and/or health products prepared by using akebiasaponin D as the active component have remarkable effects on treating and preventing fatty liver and fatty liver with hyperlipidemia, diabete and other related diseases, and have tiny toxicity.

Description

technical field [0001] The present invention relates to a new application of aketoside D, especially in the preparation of medicines and / or health products for treating and preventing fatty liver and fatty liver with hyperlipidemia and other related diseases. Background technique [0002] Fatty liver disease (FLD), referred to as fatty liver, refers to liver fat metabolism disorder caused by various factors, and the dynamic balance of lipid substances is out of balance, resulting in excessive fat accumulation in liver cells and diffuse fatty infiltration in the liver. (steatosis) and a series of pathophysiological changes in a clinicopathological syndrome, which includes alcoholic fatty liver and non-alcoholic fatty liver. Fatty liver is a frequent and common lifestyle disease among people in today's society. In recent years, the prevalence of fatty liver at home and abroad has gradually increased, and it is showing a trend of younger age. According to epidemiological survey...
