Evaluation of Hepatoprotective Activity and Acute Toxicity of Guiera Senegalensis Leaf Extract on Wistar Rats

A liver is an essential organ that performs several metabolic activities in body. Various chemicals as well as pathologies which affecting it result in harmful consequences. Management of liver pathologies involves expensive and even toxic therapeutic strategies. 80 % by populations in developing countries used medicinal plants which constituted a significant reservoir of molecules with diverse and various properties including hepatoprotective properties. To rectify these problems, Guiera senegalensis has been in existence that subjected to few studies and highlighted hepatoprotective properties, hence the interest of this study. Three extraction methods were carried out, infusion, decoction, maceration (aqueous, ethanolic). The hepatoprotective activity of the extracts was explored on 42 Wistar rats divided into 7 groups of 6 rats each. The groups including 4 test groups, were treated with the extract at 500 mg/kg of each extract. A healthy group that received distilled water (positive control group) were treated with paracetamol at 640mg/Kg. A reference group received a drug (Silymarin) The rats were treated for 14 days. The rats were then sacrificed, blood sample were collected for biochemical analyses. Some organs were removed for histological analysis as well. The acute toxicity of the extract obtained by hydro-ethanolic maceration at a dose of 2000 mg/kg was conducted in accordance with OECD guideline 420. The study of the hepatoprotective activity of plant extracts showed a significant decrease in transaminase activities in the rats treated with the extract obtained by aqueous maceration, AP, a significant decrease in total proteins in the extract obtained by hydro-ethanolic maceration. It was revealed that, the increase in in-vivo antioxidants found to be high in those treated with the hydro-ethanolic extract. The hydro-ethanolic extract did not show any significant toxicity.

Amelioration of Experimental Hepatotoxicity in Rats by Portulaca oleracea Linn. from Kashmir Himalaya.

Traditionally, Portulaca oleracea Linn. is used for treating abscesses, dysentery and liver diseases. In addition, recent studies have reported its efficacy as an analgesic, as neuroprotective, anti-inflammatory, bronchodilatory, and anticancer agent, besides antioxidant, wound healing and other important pharmacological actions. For curing liver diseases, Chinese use juice from the fresh leaves of Portulaca oleracea Linn. Hence, to prove this claim, an in-vivo hepatoprotective study of extracts from Portulaca oleracea Linn. against carbon tetrachloride hepatotoxic rats was carried out. The in-vitro antioxidant activity by using 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging assay and hepatoprotective activity of extracts of Portulaca oleracea Linn. was assessed against the carbon tetrachloride-induced toxicity rat model. The extracts of Portulaca oleracea Linn produced concentration-dependent percentage inhibition of 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical and most significantly, by methanol extract. Among the extracts, methanol extract showed a significant decrease in Serum glutamic oxaloacetic transaminase (SGOT), Serum glutamic pyruvic transaminase (SGPT), alkaline phosphatase (ALP) levels and a significant increase in total protein (TP) levels against carbon tetrachloride-induced liver toxicity. From the results obtained, it was concluded that methanol extract of Portulaca oleracea Linn. possesses significant DPPH free radical scavenging and hepatoprotective potential.

Study of laxative and hepatoprotective activity of extracts obtained from Prunus domestica fruits

The experimental work focused on the study of the pharmacological properties of extracts obtained from the Prunus domestica fruits to create a prospective laxative drug with moderate hepatoprotective properties. Prunus domestica fruit extracts have been shown to have a pronounced laxative and moderate hepatoprotective effect. Extract containing fibers at a dose of 200 mg/kg was selected as the most active extract for laxative and hepatoprotective activity among all extracts from the Prunus domestica fruits. It was conventionally named “Prunophyte”. Studies of the specific pharmacological action of “Prunophyte” extract in a model of comorbid functional constipation on the background of combined alcoholic liver disease in rats showed that “Prunophyte” at a dose of 200 mg/kg had positive dynamics in the treatment of constipation on the background of subacute liver disease. In some cases it exceeded the effects of combination therapy with drugs “Silibor” at a dose of 25 mg/kg and “Senadexin” at a dose of 14 mg/kg. “Prunophyte” extract, in contrast to “Senodexin”, did not cause signs of diarrhea in animals, which may be a beneficial feature of this drug in subsequent clinical use. This drug has shown that it can be a promising alternative to a one-time complex treatment with herbal laxatives and hepatoprotectors, which will avoid polypragmatism in the treatment of comorbid conditions in gastroenterology associated with functional constipation and liver dysfunction.

Hepatoprotective potential and chemical characterization of Artocarpus lakoocha fruit extract

<p class="Abstract">Artocarpus lakoocha fruits are widely consumed as food. The study was aimed at evaluating its hepatoprotective activity and chemical constituents. The extract was analysed by HPLC for the presence of flavonoids and phenolic compounds. Hepatoprotective potential was determined in mice following 8 days of extract or silymarin (standard therapy) administration. Hepatotoxicity was induced by administration of paracetamol (500 mg/kg). The blood and liver of treated and untreated mice were collected 24 hours post-paracetamol intoxication. HPLC analysis confirmed the presence of chromatotropic acid, quercetin, gallic acid, vanillic acid, cinnamic acid, ferulic acid and kaempferol. Acute toxicity study showed no observed effect at more than 2,000 mg/kg. The fruit extract prevented the rise in liver function tests and paracetamol related histopathological alterations. The hepatoprotective activity of extract was dose-dependent. This study confirms the preventive effect of methanolic extract of monkey jack fruits against paracetamol-induced liver toxicity.</p><p class="Abstract"><strong>Video Clip of Methodology</strong>:</p><p class="Abstract">7 min 25 sec: <a href="https://www.youtube.com/v/oyuEIJc8pqU">Full Screen</a> <a href="https://www.youtube.com/watch?v=oyuEIJc8pqU">Alternate</a></p>
