Chenopodium quinoa Willd. (quinoa), is a stress-tolerant plant, cultivated in the Andean region, used as grain, due to its remarkable content in of nutritional elements given by minerals, vitamins, fatty acids, phenolic compounds and antioxidants.The present study aimed at highlighting physical (turbidity, liquid color and cream sample) and chemical parameters (polyphenols, saponins, proteins and total sugars) from the seeds of three quinoa varieties grown in Romania in 2017. The seeds of the three varieties were subjected to the same physico-chemical determinations in three repetitions each.The obtained results have highlighted the difference between varieties in terms of the statistically influenced physical parameters compared to the values of the chemical parameters where the obtained values are not statistically assured. Thus, color liquor had values between 129 and 430 determined at 430 nm; sample cream ranged between 299.1 and 5269.70 mg/L; protein content varied between 885.19 - 962.96 mg/L; saponins between 87.61 - 92.62 mg/L and the total sugar content between 43.47 - 49.60 %.
