The antioxidant activities of five wild leafy vegetables e.g. Allium porrum, Carpesium cernuum, Tricyrtis pilosa, Spilanthes acmella, and Leea sambucina collected from Meghalaya state in India were determined by using 1,1-diphenyl-2-picryl hydrazyl (DPPH) radical scavenging activity, reducing power ability, estimation of total phenolic content, flavonoid content and flavonol content.. The results indicate that these wild edible plants can be utilized as natural antioxidant. The solvent systems used were benzene, chloroform, acetone and methanol. The different levels of antioxidant activities were found in the solvent systems used. The results indicate that these wild edible vegetables can be utilized as natural antioxidant.
