Investigating the molecular and biochemical properties of quinoa varieties

As a high value crop with natural tolerance for drought conditions, Quinoa (Chenopodium quinoa Willd) is an excellent candidate for improving food safety and food quality. It's an Amaranthacean, stress-tolerant plant cultivated along the Andes for the last 7000 years. Quinoa seeds represent potential rich sources of polyphenol compounds; they may protect cell constituents against oxidative damage and therefore limit the risk of various degenerative diseases associated to oxidative stress. In this study cellular and biochemical parameters include of total phenolic content, total free amino acids, superoxide dismutase activity, leaf total soluble protein, soluble protein SDS-PAGE and chromosomal observation in quinoa varieties cultivated in climate condition of meimeh Isfahan were investigated. Optical microscope was not a good tool for studying quinoa chromosomes. The total phenol content amongst the five quinoa varieties was significantly higher in Q29 (12.90±2.62 μg GA/mg seed). Analysis of variance of total content of free amino acids revealed significant .
