BackGround: Hedychium coronarium is a small, terrestrial, perennial rhizomatous herb, slightly aromatic plant commonly called as “Ginger Lily, Garland Flower, White Ginger”. The plant rich in Phytochemicals and Antioxidant contents used in healing inflammations in human and to treat fever, common cold etc. Object: The current study deals with the phytochemical composition and the anti-oxidant activities of the rhizomes of Hedychium coronarium. This study aims to evaluate the phytochemical and antioxidant properties of methonolic, hexane and ethyl acetate extract of rhizome of Hedychium coronarium. The plant extract shows various phytochemicals such as alkaloids, steroids, terpenoids, phenols, flavonoids, glycosides and saponins. To evaluate the anti-inflammatory activity and α-Amylase inhibition activity of rhizome extracts of Hedychium coronarium J. Koenig. Methods: To elucidate antioxidant potential, DPPH˙ radical, superoxide radical, phoshomolybdenum reduction and Fe3+ reducing power assays were done for methanol, hexane and ethyl acetate extracts of rhizome of H. coronarium. The present study aimed to evaluate the anti-inflammatory activity of alcoholic rhizome extract of H. coronarium by invitro HRBC membrane stabilization method and antidiabetic potential of methanolic rhizome extracts of H. coronarium by determining the ability to inhibit the enzyme α-Amylase.
