Abstract
Ipomoea aquatica is Convulvulaceae plant that is widely consumed in Southeast Asia as a vegetable. The plant contain various bioactive constituents, e.g. phenols and flavonoids. Water spinach and land spinach are two varieties of Ipomoea aquatica in Indoneaia. Both plants have been analyzed for their radical scavenging activity using DPPH (2,2-diphenyl-1-picrylhidrazil). Total phenol was measured using Folin Ciocalteau and total flavonoid was measured using AlCl3. Water spinach has higher antioxidant activity than land spinach and there were correlation between antioxidant activity and total phenol/flavonoid content.
