Abstract

In Vitro Evaluation of Antioxidant Activity of Methanolic Extracts of Selected Mangrove Plants

Reddy ARK and Grace JR

Antioxidants are vital substances that have an ability to protect the body from various damages caused by free radical-induced oxidative stress. Plants are the source of a wide variety of natural free radical scavenging antioxidants. The objective of the present study is to carry out in vitro antioxidant tests to evaluate the antioxidant ability of Methanolic extracts of selected mangrove plans i.e., Aegiceras corniculatum, Excoecaria agallocha and Lumnitzera racemosa. In this study, In vitro antioxidant activity was estimated by assays like DPPH, Reducing power assay and total antioxidant activity methods. The in vitro antioxidant studies revealed that, the extract of Lumnitzera racemosa has the highest phenolic content (38.80 ± 0.19 µg GAE/ 100 µg) and highest antioxidant potential. This is followed by Aegiceras corniculatum (24.06 ± 0.79 µg GAE/100 µg) and, Excoecaria agallocha (20.56 ± 0.58 µg GAE/100 µ). This study provides the preliminary data that can pave the way for further studies to validatee their medicinal uses and focus on bioassay guided fractionation and isolation of active compounds from the extracts.
