The antioxidant effect of Jumbolan ethanolic extract seeds against carbon tetra chloride induced kidney toxicity in experimental rats.

ABSTRACTBackgroundAdiantum lunulatum Burm. F. leaf (AL) and its related species have been used traditionally for the treatment of various diseases.ObjectiveThe present study evaluated the hepatoprotective, and antioxidant activities of ethanolic extract of AL.Methodology and ResultThe hepatoprotective effect of AL was evaluated against ethanol-induced hepatotoxicity in rats. Administration of ethanol (2 g/kg) showed a significant biochemical and histological deterioration in the liver of experimental animals. Pretreatment with ethanolic extract of AL (250 and 500 mg/kg b.wt. p.o) significantly reduced the elevated levels of serum enzymes like serum glutamic-oxaloacetic transaminase (AST), serum glutamic-pyruvic transaminase (ALT), alkaline phosphatase (ALP), total protein, total bilirubin and reversed the hepatic damage in the liver which evidenced the hepatoprotective activity. The superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) level notably increased due to doses of AL.ConclusionThe results of the present study demonstrate that the ethanolic extract of AL possesses hepatoprotective and antioxidant activities.Graphical Abstract

Background: Protium heptaphyllum (Aubl.) March resin is accepted as an analgesic, healing, expectorant, anti-inflammatory, antinociceptive and gastroprotective. However, there are no specific studies with leaves of this plant. Objective: This study identified the chemical composition and biological activity of crude ethanolic extract (EE) and ethyl acetate (EA) fraction from P. heptaphyllum. Methods: Mice were intoxicated with acetaminophen (PCM; 250 mg/kg), subsequently treated with EE and EA (100 mg/kg) for 7 days via gavage. Plasma analyzes and liver and kidney homogenates of the animals were performed. Results: The extract and fraction showed the presence of phenols and flavonoids. Three main flavonoids were identified by HPLC-UV, LC-MS/MS fractionation, quercetin-3-β-D-glycoside, myricetin and quercetin. For total antioxidant potential tests, EE presented EC50 of 75 μg/mL and 100 μg/mL for EA. ALT, AST and ALP enzymes activity increased in the PCM-exposed plasma, but EA decreased these activities at control levels for ALT and AST. Animal glycemic levels decreased with EE and EA, which may be due to a possible hypoglycemic effect of the plant. In liver tissue, SOD was unchanged, CAT, GSH and ASA decreased in the PCM group, but EA was able to reverse these effects. TBARS and PC were reduced by both treatments. In renal tissue, EA fraction recovered GST activity, GSH levels were restored by EE and EA and PC was reduced by treatments. Conclusion: This antioxidant effect may be due to the presence of the flavonoids identified which are already well known for their antioxidant properties.
