Effects of Ethanolic Extract of Arrowroot Tubers (Maranta Arundinacea L.) on the Level of MDA, SGPT and SGOT in Ethanol Induced Rats

Background : The exposure of free radicals can induce oxidative stress. In the liver, this process will cause impaired liver function. Oxidative stress can be inhibited by antioxidants. Arrowroot tubers (Maranta arundinacea) contains phenolic, flavonoid, alkaloids and saponin compound that are potential as antioxidants. Objective : Determine the effect of ethanolic extract of arrowroot tubers (Maranta arundinacea) against oxidative stress using the parameter of MDA, SGPT and SGOT level in ethanol-induced rats. Methods : Animal models were divided into 5 groups, in which each group contained 6 rats. Group I (normal) and group II (control) was induced with CMC Na 0,5%. Group III, IV and V were given ethanolic extract of arrowroot tubers in the dosage of 125, 250 and 500 mg/Kg/day respectively. The extract was administered orally for 14 days. Induction of ethanol 5 gram/ KgBW was administered orally 1 hour after the last administration on day 14th except for group I. On day 15th, the animal blood was drawn to measure the levels of SGPT and SGOT, then the animals were sacrificed and their organs were analyzed to measure the levels of MDA in the liver. Data obtained in the form of MDA, SGPT and SGOT levels were statistically analyzed using ANOVA. Results : There is statistically significant difference between the utilization of ethanolic extract of arrowroot tubers (Maranta arundinacea) group with the control group in reducing the concentration of MDA (p<0,05), SGPT, and SGOT (p<0,05). Conclusions : The ethanolic extract of arrowroot tubers (Maranta arundinacea) is able to reduce the concentration of MDA, SGPT and SGOT in ethanol-induced rats

Green Product Purchasing Phenomenon: Exploring the Gaps of Theoretical, Methodological and Empirical

This study aims to identify research gaps on green purchasing topics and proposes several recommendations for future research. To explain the phenomenon of green products purchase, this study uses Theory of Planned Behavior (TPB) in framework. The research uses a qualitative method approach by conducting a review of articles that traced through four popular journal providers: Ebsco, J-Stors, Proquest and Emeraldinsight. A literature search process held between April, 2015 until Juni, 2015 and resulted on 67 chosen articles. The outcome of the review identified four theoretical gaps, two methodological gaps and one practical gap
