Phytochemical and pharmacological profiles of two wild edible plants: Natsiatum herpeticum buch.-ham. ex arn and Sphenoclea zeylanica gaertn. of north-east India

Natsiatum herpeticum and Sphenoclea zeylanica plants are known to contain minerals and many bioactive compounds which provide several health benefits on consumption. The present review aimed to glorify the nutritional composition, phytochemical constituents, metal contents, amino acid analysis, anti-nutritional content, antioxidant properties, and anti-microbial analysis of two wild edible plants, N. herpeticum and S. zeylanica of North-East India. The total phenolic and vitamin C content in N. herpeticum is higher than in S. zeylanica, but the flavonoid content is the same in both plants. The metal contents are the same in both plants, although the potassium content is too high. The plant S. zeylanica contains sixteen essential and non-essential amino acids, and their quantitative estimation was also evaluated. It was found that S. zeylanica contains high oxalate. The antioxidant property of N. herpenticum and S. zeylanica was carried out by three. DPPH free radical scavenging activity, ABTS free radical scavenging activity, and Hydrogen peroxide. The antioxidant property of S. zeylanica is comparatively more than that of N. herpenticum. The leaves of S. zeylanica have significant antimicrobial activity.
