Objective: To isolate and evaluate the hepatoprotective activity of the crude ethanolic leaf extract of Averrhoa bilimbi Methods: The leaves of Averrhoa bilimbi were extracted by cold maceration using ethanol as a solvent, and the solvent fractions were obtained with petroleum ether and ethyl acetate. Preliminary phytochemical tests were performed for the presence or absence of secondary metabolites. Plant chemical constituents were isolated using column chromatography and characterized by IR,1HNMR,13CNMR and mass spectroscopic values. Albino rats were treated with the vehicles (distilled water or 2% Tween 80), three different doses (100, 200 and 400 mg/kg) of the crude ethanol extract and the standard drug (silymarin 100 mg/kg), and the hepatotoxicant paracetamol. Then, the levels of biomarkers of liver injury – such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) – and liver function such as bilirubin were measured along with histopathological examination. Results: Preliminary phytochemical studies shown the presence of n-docosanoic acid and beta sitosterol from petroleum extract and from ethyl acetate a flavonoid apigenin.The ethanol extract suppressed the plasma levels of AST, ALT and ALP (P=0.05) in the aforementioned doses. Maximum hepatoprotective activity was observed at the dose of 400 mg/kg body weight. Conclusion: Averrhoa bilimbi is endowed with hepatoprotective activity, probably with the presence its chemical constituents like sterols,flavonoids and terpenoids.

Ethnopharmacological relevance: The dry leaf of Alchornea cordifolia (AC) is used, in traditional medicine in the S Nigeria, for the preparation of blood tonic, remedies for urinary, respiratory, liver and gas intestinal disorders. Aim of the study: This study investigated the protective property of AC leaf against liver damage in animals with a view to exploring its use for the treatment of hepatotoxicity in humans. Material and methods:  Ethanol extract of A. cordifolia was used to study the hepatoprotective activity in acetaminophen-induced Albino rats (150-200g). Animals in Group 1 served as vehicle control, Group 2 served as hepatotoxin (Acetaminophen 2g/kg treated) group, Groups 3 and 4 served as positive control (Vitamin E and Curcumin 100 mg/kg bw respectively) groups, and Groups 5-8 served as (200-500mg/kg bw) AC leaf extract treated groups while Group 9 served as normal group (AC extract only 300 mg/kg bw). Results: The hepatotoxic group showed hepatocytic necrosis, cellular infiltration and inflammation in the liver. The treatment group restored the liver cells to their normal lobular architecture in a dose dependent manner. The protection offered by the plant extract compared well with the standard antioxidant agents (Curcumin and Vitamin E). Tannins, flavonoids, alkaloids and saponins were detected in the phytochemical screening. Conclusion: Our findings suggest Alchornea cordifolia ethanol leaf extract as promising herpatoprotective herb and give credence to the folkloric use of this plant for the treatment of liver problems.DOI: http://dx.doi.org/10.3126/ijasbt.v2i2.10473Int J Appl Sci Biotechnol, Vol. 2(2): 217-221

The study assessed the in vivo antioxidant and hepatoprotective activity of an ethanol (70%) extract of Momordica tuberosa Cogn. (Cucurbitaceae) (TMT) tubers in experimentally induced liver damage by paracetamol (2 g/kg, po.) in albino rats. The degree of protection was ascertained by estimating the levels of biochemical markers like SGPT, SGOT, bilirubin (total and direct), ALP, and triglycerides. Tissue GSH and lipid peroxidation were also determined. The ethanol (70%) extract of tubers in an oral administration of 20 and 40 mg/kg doses produced significant protection by decreasing the activity of serum enzymes, bilirubin, cholesterol, triglycerides and tissue lipid peroxidation, while it increased tissue GSH at 40 mg/kg dose. The effects of the extract were comparable to the standard drug silymarin (100 mg/kg). Results suggested that an ethanol (70%) extract of the tubers of the plant at 40 mg/kg possesses potential hepatoprotective activity against paracetamol-induced hepatic damage and significant antioxidant activity in rats.

Disease cancer caused by abnormal growth of tissue where there has been an error, fast and out of control. Judging from the fact of gender, more than 270,000 women die every year caused by cervical cancer. To inhibit the growth of cancer cells, a compound is needed that causes the cell cycle to stop so that the ability of cell proliferation decreases. Alkaloid compounds can inhibit proliferation through oxidative inhibition processes that can cause cancer. Mangrove plants have potential as anticancer, antimicrobial, and antioxidant. The content of chemical compounds found in mangroves are flavonoids, steroids, alkaloids, phenolites, saponins and tannins. These compounds show high antioxidant activity and are shown to have a real relationship with the properties of the material's bioactivity against cancer cells. One of the mangrove species is Rhizophora apiculata. The purpose of this study was to determine the IC50 value produced by Rhizophora apiculata mangrove leaf extract on HeLa cell viability and to see the effect of Rhizophora apiculata mangrove leaf extract dosage on HeLa cell viability. The method used in this research is the experimental method. The research parameters included yield, proximate test, phytochemical test, toxicity test, total phenol test, cytotoxicity test and LC-MS test. The experimental design used was a simple and complex completely randomized design (CRD) with the Tukey test.The results of this study showed that the highest yield was in the ethanol extract of 5.91%, while the n-hexane and ethyl acetate extracts respectively had yields of 1.18% and 1.31%. The results of the proximate test on the water content of leaves and powder were 64.53% and 13.86%, respectively, the results of the ash content in the leaves and powder of Rhizophora apiculata were 3.94% and 8.41%, respectively. while the water content in the extract obtained the highest yield in the ethanol extract of 21.42%, while the n-hexane extract and ethyl acetate extract were 11.08% and 15.42%, respectively. For phytochemical results, it was found that n-hexane extract only contained alkaloids, flavonoids and steroids. Ethyl acetate extract contains steroid compounds. Meanwhile, the ethanol extract contains the most bioactive compounds, namely saponins, flavonoids, tannins and triterpenoids. The toxicity test using the Brine Shrimp Lethality Test (BSLT) method resulted in the lowest IC50 of ethanol extract at 49.45 ppm while the n-hexane and ethyl acetate extracts were 251.63 ppm and 920.45 ppm respectively. In the total phenol test, the n-hexane extract was 66.79 mg GAE / 100 gr, 222.97 mg GAE / 100 gr ethyl acetate extract and 929.04 mg GAE / 100 gr ethanol extract. HeLa cell cytotoxicity testing using the MTT method (3- (4,5-dimethiltiazol-2-yl) -2,5-dipheniltetra zolium bromide) assay resulted in the highest cell viability value at a dose of 125 ppm of 46.97%. As for the doses of 250 ppm, 500 ppm 1000 ppm, and 2000 ppm resulted in a percentage of viability of 42.95% 37.70% 35.82% and 32.12%, respectively. The IC50 value of Rhizophora apiculata leaf extract was 64.42 ppm. This value indicates that the Rhizophora apiculata extract is toxic to HeLa cells.

<p>The study was designed to evaluate the hepatoprotective activity of aqueous extract of cardamom in acute experimental liver injury induced by gentamicin. Twenty four male albino rats were randomly divided into four groups (six rats in each). Animals of the first group served as control and orally (p.o.) received (1 ml/kg saline). The second experimental group was given gentamicin (80 mg/kg i.p.) for 7 days. Third and fourth groups were given aqueous extract of cardamom (100 and 200 mg/kg p.o.) + gentamicin for 7 days, respectively. The degree of hepatoprotection was measured using serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), bilirubin, albumin, and lipid profile levels. In the acute liver damage induced by gentamicin, cardamom aqueous extracts (100 and 200 mg/kg, p.o.) significantly reduced the elevated serum levels of AST, ALT, bilirubin, cholesterol, triglycerides and low density lipoprotein cholesterol (LDL-chol) in gentamicin induced hepatotoxicity. Also cardamom aqueous extracts (100 &amp; 200 mg/kg, p.o.) significantly increased the lowered serum levels of albumin and high density lipoprotein cholesterol (HDL-chol) in gentamicin induced hepatotoxicity rats. Histopathological examination of the liver tissues supported the hepatoprotection. Our findings concluded that cardamom aqueous extracts possessed hepatoprotective activity against gentamicin induced hepatotoxicity in rats.</p>
