ABSTRACT

The present study aims to investigate the phytochemical screening, antioxidant and anti-diabetic activity of commonly used fruits, Musa acuminata Red Dacca (Red Banana), Citrus sinensis (Orange) and Phyllathus emblica (Amla). Edible part of Phyllanthus emblica, Musa acuminata Red Dacca and peel of Citrus sinensis are taken for the study. The phytochemical screening of ethanolic extract of Musa acuminata revealed strong presence of carbohydrates and glycosides and moderate presence of tannins, proteins, flavonoids, steroids and phenols. The ethanolic extract of Citrus sinensis showed abundance of flavonoids and least presence of carbohydrates, proteins and steroids. Strong presence of phenol was shown in Phyllanthus emblica and all the others were present in least amount. The antioxidant activity was determined by ferric reducing power assay (FRP) where Phyllanthus emblica showed maximum activity that was followed by Citrus sinensis peel and then Musa acuminata. α-Amylase inhibitory assay was performed to detect the antidiabetic activity of these fruits by comparing with  commercially available drug Okamet. It was Phyllanthus emblica that used lowest concentration to inhibit the enzyme which was found similar to positive commercial standard Okamet that is used for reducing blood sugar level. Hence it can be concluded that Phyllanthus emblica has good antioxidant and antidiabetic property than Musa acuminata and Citrus sinensis.

Keywords: Musa acuminata, Citrus sinensis, Phyllanthus emblica, Okamet.
