| 1 | Insecticidal,antimicrobial and antioxidant activities of bulb extracts of Allium sativum显示文摘Objective:To evaluate the insecticidal,antimicrobial and antioxidant activities of bulb extracts of Allium sativum(A.sativum).Methods:Dried bulbs of A.sativum were extracted with different solvents and evaluated for insecticidal,antimicrobial and antioxidant activities.Results: Aqueous and methanol extracts showed highest insecticidal activity(mortality rate of 81%and 64%respectively) against the larvae of Spodoptera litura(S.litura) at a concentration of 1000 ppm.With regard to antimicrobial activity,aqueous extract exhibited antibacterial activity against gram positive(Bacillus subtilis,Staphylococcus aureu,) and gram negative(Escherichia coli and Klebsiella pneumonia) strains and antifungal activity against Candida albicans.While methanol extract showed antimicrobial activity against all the tested micro organisms except two(Staphylococcus aureus and Candida albicans),the extracts of hexane,chloroform and ethyl acetate did not show any anti microbial activity.Minimum inhibitory concentration of aqueous and methanol extracts against tested bacterial and fungal strains was 100-150μg/mL. Antioxidant activity of the bulb extracts was evaluated in terms of inhibition of free radicals by 2.2’-diphenly-l-picrylhydrazyl.Aqueous and methanol extracts exhibited strong antioxidant activity(80%-90%of the standard).Conclusions:Antioxidant and antimicrobial activity of A.sativum against the tested organisms therefore,provides scientific basis for its utilization in traditional and folk medicine.Also,our results demonstrated the insecticidal efficacy of A. sativum against S.litura,a polyphagous insect. | Balaji Meriga Ramgopal Mopuri T.MuraliKrishna | 2012 | Asian Pacific Journal of Tropical Medicine2012，5，5： | 5 |
| 2 | In vitro anti oxidant activity and acute oral toxicity of Terminalia paniculata bark ethanolic extract on Sprague Dawley rats显示文摘Objective:To ensure the safety and evaluate the anti oxidant activity of Terminalia paniculata(T.paniculata)ethanolic extract in Sprague Dawley rats.Methods:The solvent extracts(hexane,ethyl acetate and ethanol)of T.paniculata were subjected to phytochemical analysis and their DPPH radical scavenging activity was assayed.The oral acute toxicity was evaluated using ethanolic extract of T.paniculata.Results:Ethyl acetate and elhanolic extracts showed more phytochemicals,whereas highest DPPH scavenging activity was found in ethanolic extract.In an acute toxicity study,T.paniculata ethanolic extract was orally administered(1000 mg/kg body weight)to rats and observed for72 h for any toxic symptoms and the dose was continued up to 14 d.On the 15th day rats were sacrificed and blood samples were collected from control and test animals and analyzed for some biochemical parameters.We did not observe any behavioral changes in test groups in comparison with their controls.Also,there were no significant alterations in biochemical,hematological(hemoglobin content and blood cells count)and liver function parameters such as serum glutamate pyruvate transaminase,serum glutamate oxaloacetate transaminase,alkaline phosphatase,total proteins,albumin and bilirubin levels between T.paniculata ethanolic extract treated and normal control groups.Conclusions:Together our results demonstrated that T.paniculala ethanolic possessed potent antioxidant activity and it was safer and non toxic to rats even at higher doses and therefore could be well considered for further investigation for its medicinal and therapeutic efficacy. | Ramgopal Mopuri Balaji Meriga | 2014 | Asian Pacific Journal of Tropical Biomedicine2014，4，4： | 1 |
