Hepatocurative potential of Vitex doniana root bark, stem bark and leaves extracts against CCl4–induced liver damage in rats

Abstract The harmful effects that accompany the use of orthodox antioxidant medicine have necessitated the hunt for inherent antioxidants from plants extracts. In the present study, the in vivo antioxidant and hepato-protective activities of Vitex doniana against carbon tetrachloride (CCl4) induced liver damage in albino rats were investigated. The hepato-protective activities of the methanol extract of Vitex doniana stem bark were compared with Silymarin, a known hepatoprotective drug. Twenty-five (25) male albino adult rats were grouped into five (5) each. Group 1 and 2 was used as the normal and negative control respectively. Group 3-5 were treated with 200 mg/kg, 400 mg/kg methanol extract of Vitex doniana stem bark and 100 mg/kg Silymarin respectively. Results indicated that elevated levels of serum ALT, AST and ALB, and reduced serum SOD, GST and CAT in CCl4-hepatotoxic rats was an evidence of impairment in liver function. Administration of methanol extract of Vitex doniana stem bark (200 and 400 mg/kg body weight) and standard control drug Silymarin (100 mg/kg) have no significant (P>0.05) effect on CCl4- induced elevations of the ALT and AST levels while the reduction in albumin concentration, total proteins, SOD, GST and CAT due to CCl4 was reversed. In conclusion, Vitex doniana exhibited significant antioxidant and hepatoprotective properties in CCL4 induced liver damage in rat, and thus could be used and incorporated in the development of new and effective antioxidant drugs.

Vitex Doniana

To determine the effect of Vitex doniana (leaves stem and root bark) ethanol extracts on lipid profiles of Poloxamer 407 (P-407) induced hyperlipidemic and normal rats. Fifty four mixed sex rats weighing 100-200g were divided into nine groups comprising six animals per group: group given feed and water only, group induced by an intra-peritoneal injection of P-407 every 48hours without treatment, groups induced and treated with atorvastatin, leaves, stem bark, root bark extracts and groups of normal rats treated with leaves, stem bark and root bark extracts without induction. In all the groups, P-407, atorvastatin, leaves, stem bark and root bark extracts were administered at a dose of 1000mg/kg, 20mg/kg, 100mg/kg, 100mg/kg and 30mg/kg body weight respectively. At the end of the 21day, the animals were sacrificed and blood sample were collected for determination of serum levels of: Total cholesterol (TC), Triacylglycerides (TAG), High-density lipoprotein cholesterol (HDL-c) and Low-density lipoprotein cholesterol (LDL-c). The studies showed that all induced treated groups significantly (P<0.05) lower serum levels of TC, TAG, LDL-c and significantly (P<0.05) increased HDL-c when compared to the P407 induced hyperlipidemic control. The normal treated groups showed no significant (P>0.05) difference in the serum levels of TC, TAG, LDL and HDL when compared to the normal control group. Calculation of atherogenic risk predictor indices of the induced treated groups showed that all the extracts significantly (P<0.05) lowered the LDL-c/HDL-c, log (TAG/HDL-c) and significantly (P<0.05) increased HDL-c/TC ratio when compared to the P407 induced hyperlipidemic control group. The atherogenic risk predictor indices of normal treated groups showed no significant difference (P>0.05) in LDL-c/HDL-c, Log (TAG/HDL-c) and HDL-c/TC ratio when compared to the normal control group. The study demonstrates the phytotherapeutic effect of Vitex doniana (leaves, stem and root bark) ethanol extract in poloxamer 407 induced hyperlipidemia.

Alstonia venenata R. Br. belonging to the family Apocynaceae is a tall evergreen shrub distributed throughout Peninsular India. Stem-bark, root-bark, fruits and leaves are used by many tribal communities and also in Ayurveda. The study investigates the phytochemical composition of hexane, butanol, methanol and water extracts of Alstonia venenata fruits and flowers as well as the TLC profile of hexane extracts of fruits and flowers. Quantitative data of the wet and dry weight, yields from different solvent fractions and percentage yields were noted. The phytochemical analysis revealed the presence of secondary metabolites such as alkaloids, steroids, terpenoids, saponins, flavonoids, tannins and phenolic compounds from the various extracts. Alkaloids were present in all the fractions tested. Methanol extracts of fruits and flowers showed the presence of major phytoconstituents. TLC profile of hexane extracts of fruits and flowers were developed using anisaldehyde sulphuric acid/ceric sulphate (steroids/terpenoids) and Dragendorff’s spray reagents (alkaloids). Petroleum ether: Chloroform: Methanol (5: 4.5: 0.5) showed good resolution for the hexane extracts of fruit and flower when treated with Dragendorff’s spray reagent. Petroleum ether: Chloroform (1:1) was best for the hexane exacts of flowers and fruits when sprayed with ceric sulphate spray reagent

Vitex Doniana

Background: Oxidative stress is involved in the pathogenesis of hypertension, myocardial ischemia-reperfusion injury, atherosclerosis, muscular dystrophy, aging and other associated diseases. Vitex doniana is used in Adamawa, northern Nigeria to treat oxidative stress associated diseases. However, the antioxidative effects of the plant have not been scientifically examined in oxidative stress experimental animal models. The aim of this study is to investigate the in vitro and in vivo antioxidant activities of aqueous and ethanol stem bark extracts of Vitex doniana in oxidative stress model of rats. Methods: The study used 35 adult albino rats weighing 175 ± 25 g, of which 30 were induced with oxidative stress by intraperitoneal injection of doxorubicin (10 mg/kg) for three consecutive days. Animals were treated by oral administration of silymarin (100 mg/kg) and Vitex doniana aqueous or ethanol extract (100 mg/kg and 200 mg/kg) for 14 consecutive days before they were sacrificed on the 15th day and blood was analyzed for biochemical indices of oxidative stress. Results: The results of the phytochemistry showed the presence of alkaloids, tannins, flavonoids, steroids, phenols, saponins, terpenoids, glycosides: and total flavonoids (52.70 ± 1.60 mg/ml and 75.40 ± 0.80 mg/ml), total phenols (21.45 ± 1.54 mg/ml and 26.50 ± 1.22 mg/ml) for aqueous and ethanol stem bark extracts respectively. The extracts scavenged DPPH radical, reduced Fe3+ and inhibited lipid peroxidation. Doxorubicin significantly (p<0.05) lowered the levels of SOD, CAT, GR and TAS and significantly (p<0.05) but, increased the level of LPO. Oral treatment with Vitex doniana extracts significantly (p<0.05) increased the activities of CAT, GR, SOD and TAS while LPO was significantly (p<0.05) lowered. Vitex doniana stem bark extracts significantly (p<0.05) improved the biochemical derangements observed in the induced untreated animals in comparable manner to that of Silymarin. Conclusion: The present study provides the scientific rationale for the use of Vitex doniana stem bark in traditional medicine and has a viable antioxidative capacity both in vitro and in vivo.
