Abstract

The present study investigated the effects of ethyl acetate fraction of Mangifera haden seeds on carbon tetrachloride-induced liver damage in wistar albino rats. The phytochemical compositions and acute toxicity studies of crude extract and Mangifera haden seed fraction were determined using standard methods. Albino rats (60) randomly grouped into twelve of five rats each were used for this study. Determination of total bilirubin and protein, lipid peroxidation, liver enzymes marker, antioxidant enzymes, glutathione, lipid profile analysis and histological examination were carried out using standard methods. Phytochemical constituents of crude extract and ethyl acetate fraction of Mangifera haden seed showed that they contain relative amount of flavonoids, phenolics, saponins, tannins, terpenoids, triterpenes, alkaloids and coumarins. Liver injury was induced with carbon tetrachloride (CCl4) at a dose of 1.0 ml/kg body weight of the animals. All the CCl4 intoxicated rats displayed hyperlipidemia as shown by their elevated levels of serum total cholesterol (TC), triacylglycerol (TAG), low density lipoprotein (LDL), and reduction in high density lipoprotein (HDL) levels. The administration of ethyl acetate fraction of Mangifera haden seeds significantly (P = 0.05) lowered the levels of serum TC, TAG, LDL, and increased HDL levels. The level of serum malondialdehyde (MDA) significantly (P = 0.05) increased in the CCl4 group as compared to the normal and treated groups. The elevated level of serum MDA decreased (P = 0.05) significantly at the treatment of rats with 200, 400 and 600 mg/kg of ethyl acetate fraction. The rats treated with CCl4 produced significant (P = 0.05) increase in serum ALT, AST and ALP when compared to the normal group. Animals treated with varying doses of ethyl acetate fraction produced significant (P = 0.05) reduction of serum ALT, AST and ALP activities when compared to the CCl4-untreated group. The activities of hepatic antioxidant enzymes (SOD, CAT and GPx) and glutathione concentration significantly (P = 0.05) decreased in CCl4­-untreated group compared to the normal group. The decreased activities of the antioxidant enzymes and glutathione concentration in CCl4 intoxicated rats were ameliorated/modulated more effectively in rats treated with 200, 400 and 600 mg/kg ethyl acetate fraction of Mangifera haden seed. Total bilirubin (TB) concentrations significantly (P = 0.05) increased in CCl4-untreated group when compared to the normal group. Oral treatment of rats with varying doses (200, 400, 600 mg/kg) of ethyl acetate fraction caused a significant (P = 0.05) decrease in the serum TB levels. Administration of CCl4 showed a reduction in serum total proteins. Treatment of the animals with 200, 400 and 600 mg/kg of ethyl acetate fraction caused significant (P = 0.05) increase in serum total potein. Histological examination showed hepatoprotective properties of plant’s fractions. The compounds found in the different fractions (ethyl acetate and n-hexane) of Mangifera haden seeds are 9-Octadecenoic acid (Z)-, methyl ester, (Z) –Oleic acid and so on. Therefore the medicinal importance of the plant is been established.
