Green leafy vegetables occupy an imperative place among the food crops as they provide adequate amounts of
carbohydrates, proteins, vitamins and minerals for consumers. Despite their nutritive value, nowadays greens remains
underutilized due to lack of awareness and promotion of appropriate technologies for their effective utilization,
modernization. Aerial parts of Amaranthus tristis and Basella alba were chosen to investigate their phenolic,
flavonoid, carbohydrate and protein contents tagged with essential in vitro antioxidant assays viz. Radical scavenging
activities (DPPH°, OO°, H2O2), reducing power, inhibition of lipid peroxidation (TBARS), to make them potentially
accessible source of natural antioxidant. By employing sequential solvent extraction, an overall significant activity was
established by acetone extract of Amaranthus tristis stem for majority of the assayed experiments, in particular
phenolic (1.730 mg), carbohydrate (149.109 mg), DPPH (0.166 mg). In competence, better significance was reported
by methanol fractions of Amaranthus tristis, Basella alba leaves and acetone fraction of Basella alba stem, which
articulated to assess its antibacterial and antifungal activities. At the outset, Amaranthus tristis stem demonstrated its
potent effect and an interest to study the constituents present in it through GC-MS analyses was analyzed to study
the major constituents present. This piece of work to endow the scientific validation of these plants for their
medicinal, therapeutic, dietary applications etc.
