Vitamin-A is a known powerful natural antioxidant and an essential vitamin for vision. It is also required to maintain healthy mucosa and skin. Consumption of natural vegetables and fruits rich in vitamin-A is known to help to protect from lung and oral cavity cancers.

Furthermore, present in purslane are two types of betalain alkaloid pigments, the reddish β -cyanins, and the yellow β -xanthins. Both pigment types are potent antioxidants and have been found to have antimutagenic properties in laboratory studies. [Proc. West. Pharmacol. Soc. 45: 101-103 (2002)].
