Abstract :

Excoecaria agallocha a milky mangrove, blind your eye mangrove, or a river poison tree is widely distributed in Indian coastal regions. The present study focuses on evaluation of phenolics and flavanoids present in Excoecaria agallocha. The FTIR analysis of various mangrove extract is also studied .The FTIR analysis showed the presence of flavones, alcohol,arenes,aliphatic functional group. Total phenolic content (TPC) expressed as gallic acid equivalents (GAE) ranged from 6.3�0.4 (whole plant petroleum ether extract) to 10.83�0.7 (stem methanol extract) mg GAE/g dry weight. Total flavonoid content expressed as quercetin equivalents (QE) ranged from 9.2�0.9 (whole plant ethyl acetate extract) to 33.8�0.9 ( leaf methanol extract) mg QE/g dry weight. Antioxidant activity determined by DPPH assay is highest(83.3 �3.2%) in methanol extract. Keywords: Excoecaria agallocha ,halophyte, TPC , TFC, antioxidant, DPPH assay, FTIR.
