The antioxidant activity of the fruit extract was determined in vitro using the DPPH method. In vitro antidiabetic activity of fruit extract was observed by starch-agar gel diffusion method. The Antilipase activity of the aqueous fruit extract was assessed by the Rhodamine agar plate method. The results of the present study conclude that Hylocereus undatus juice extract possesses antioxidant, antidiabetic and antilipase activities. Phytochemical screening of the white dragon fruit showed the presence of triterpenoid, alkaloid, flavonoid and saponin.en-USDairy ScienceArticle
