The study estimated bioactive compounds in various parts of Morinda citrifolia L. with special reference on fruits, leaves and seeds. Significant (p < 0.05) differences were observed in various parts for polyphenol, flavonoids, tannins, carotenoids, ascorbic acid, nitrate, oxalate and phytate contents. Determination of DPPH antioxidant activity of different parts revealed that aqueous extract scavenged significantly (p < 0.05) more DPPH free radicals than methanol and acetone extracts. Val-Tyr-Val and Meth-enkephalin polypeptides were high in leaves while Ly-Tyr and Leu-enkephalin in fruits. Fatty acid profiles of Morinda seeds revealed them as rich source of linolenic acid, stearic acid, oleic acid and lauric acid. Strong correlations were observed between antioxidant activity and carotenoids (R (2) = 0.774, p = 0.021). Information on bioactives and high free radical scavenging activity of M. citrifolia parts supports their various health claims.
