Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of medicine, and particularly relates to a ginkgolide composition and its application in the preparation of drugs for preventing and / or treating hemolytic jaundice. Background Art
[0002] Hemolytic jaundice is caused by various factors leading to hemolysis, excessive destruction of red blood cells, formation of a large amount of unconjugated bilirubin, which exceeds the uptake, conjugation, and excretion capacity of hepatocytes; on the other hand, due to anemia, hypoxia, and the toxic effects of red blood cell breakdown products caused by hemolysis, the metabolic function of hepatocytes for bilirubin is weakened, resulting in the retention of unconjugated bilirubin in the blood, exceeding the normal level and presenting jaundice.
[0003] Ginkgo biloba contains chemical components such as flavonoids, terpene lactones, phenolic acids, polyprenols, etc. Ginkgo biloba extract (GBE) is an extract isolated and purified from Ginkgo biloba leaves, mainly containing flavonoid and terpene lactone compounds, which are the main active components of Ginkgo biloba leaves and have strong pharmacological activities. Ginkgo biloba extract is prepared from Ginkgo biloba leaves by ethanol reflux extraction. The extraction solutions are combined and concentrated to an appropriate amount, and then eluted successively with water and ethanol of different concentrations on a macroporous adsorption resin column. The eluates are collected, ethanol is recovered, and the dried extract with enriched active ingredients is obtained, which is a light yellow-brown, flowable powder with a bitter taste. The Chinese Pharmacopoeia (2020 Edition) stipulates that, calculated on the dried product, the content of total ginkgo flavonoids (including quercetin, kaempferol, isorhamnetin) is ≥ 24.0%, the content of terpene lactones (including bilobalide, ginkgolide A, ginkgolide B, ginkgolide C) is ≥ 6.0%, and the total ginkgolic acid content shall not exceed five parts per million.
[0004] Ginkgolide is a terpene compound, also known as ginkgo terpene lactone, which is composed of sesquiterpene lactones and diterpene lactones and is an active ingredient of Ginkgo biloba leaves. The diterpene lactones among them include ginkgolide A, ginkgolide B, ginkgolide C, ginkgolide J, ginkgolide M, ginkgolide K, and ginkgolide L, while the sesquiterpene lactone is bilobalide. As a main active ingredient in GBE, ginkgolide has obvious effects on diseases such as stroke and Alzheimer's disease. Ginkgolide is a strong platelet-activating factor antagonist, which has a protective effect on ischemic injuries of the central nervous system and immune system, and also has anti-allergic and anti-shock effects.
[0005] There are many methods for the extraction and purification of ginkgolides, but none of them can effectively isolate ginkgolides with high content. Moreover, the components of the terpene lactones obtained by different separation processes are different, which leads to different drug effects of the ginkgolides prepared by different extraction and purification methods. The present invention provides a ginkgolide composition with a fixed component ratio and a clear and definite product structure, and creatively uses it in the preparation of drugs for preventing and treating hemolytic jaundice. So far, there has been no relevant report. Summary of the Invention

[0028] Another object of the present invention is to provide an application of a ginkgolide composition in a drug for preventing and / or treating hemolytic jaundice.
[0029] Furthermore, the hemolytic jaundice is congenital hemolytic jaundice or acquired hemolytic jaundice.

[0068] 1. Experimental Materials
[0069] 1.1 Drugs
[0070] Ginkgolide composition, provided by Shandong Xinsdai Pharmaceutical Co., Ltd., prepared according to the method of Preparation Example 1 above;
[0071] Acetylphenylhydrazine, sourced from Aladdin, batch number L2106080.
[0072] 1.2 Experimental animals
[0073] 50 male ICR mice, 6 - 7 weeks old, weighing 30g - 34g.

[0076] The 50 mice were randomly divided into a normal control group, a model control group, a YXNZ - L group, a YXNZ - M group, and a YXNZ - H group according to body weight, with 10 mice in each group. Except for the normal control group, mice in other groups were intraperitoneally injected with 60mg / kg acetylphenylhydrazine (APH) on the first day, and 30mg / kg acetylphenylhydrazine (APH) was intraperitoneally injected every day after 48h to maintain the model. The normal control group was injected with an equal volume of normal saline, and the model establishment period was 19 days. At the same time as the start of model establishment, each administration group of the ginkgolide composition was given the ginkgolide composition by gavage every day for 21 consecutive days. The model control group and the normal control group were given an equal volume of solvent. Compared with the normal control group, the mice in the model control group were irritable, their fur lost luster, the skin of their ears and other parts turned yellow, and their urine and feces were yellow, indicating successful model establishment.

After continuing to administer the drug for 21 days, the mice in the low-dose group of the ginkgolide composition showed a slight improvement in sluggishness compared with before, ate and moved occasionally, had light yellow ears, soy sauce-colored urine, red and slightly loose stools, and there were still cases of lying prone, twitching, irritability, and huddling together, and slight escape and struggle phenomena began to appear when grabbed. In the medium- and high-dose groups of the ginkgolide composition, the reaction of the mice improved compared with before, they could respond to stimuli, the amount of eating and activity increased, the fur began to show slight moistening, the ear skin began to turn red and was light pink, the urine was lighter yellow than before, the stools were slightly formed, the color began to darken, and the cases of lying prone, twitching, irritability, and huddling together improved significantly.
