Comparative assessment, optimization and characterization of bioactive constituents from Amaranthus species: An indigenous lesser-known vegetables of India

Amaranthus Tricolor L. (red amaranth) and Viridis (Green are Amaranthaceae members, widely cultivated in Asia consumed as a leafy vegetable many parts of the world. This study deal with nutritional functional, biochemical characterization A. viridis . Single-factor experiments Box Behnken Design (BBD) were used to optimize extraction process for phenolic compound from The BBD shows that 11.87mg/g extract produced at optimal condition solid water ratio (1:15), temperature (30°C), time (15 min). Similarly, isolated 18.36mg/g phenolics liquid (1:30), (60 radical scavenging activity 63.52% 19.27%, respectively, by DPPH method. bioactive compounds 3,4,5-Trihydroxystilbene caffeic acid found Tricolor, it showed acid, which was identified using LC-MS/MS.
