The aim of this work was to estimate the total phenolic and flavonoid content, and to evaluate in-vitro antioxidant activity of ethanolic root extract of Morinda Citrifolia (MCREt). The raw, dry root powder was extracted with 99.9% of ethanol. Phytochemical test shows that extract contains higher level of total phenol and flavonoids. Total phenolic compound in ethanolic root extract of Morinda Citrifolia was found to be 41.89 mg/g of extract calculated as gallic acid equivalent (r2=0.9971) and total flavonoids compound was found to be 17.27 mg/g of extract calculated as rutin equivalent (r2=0.9992). The extract was screened for its potential antioxidant activities using tests such as hydroxyl radical-scavenging activity, reducing power activity, and hydrogen peroxide-scavenging activity. The in-vitro antioxidant assay showed MCREt posses potent antioxidant activity when compared with reference compound butylated hydroxytoluene (BHT). MCREt could be useful for preparation of neutraceuticals as potent antioxidant to treat various human diseases and its complications.
