Keeping in view the potentiality and wide variability of the crop, fifteen landraces were collected from different parts of North Eastern Region of India and evaluated for its biochemical components at the College of Horticulture and Forestry, Central Agricultural University, Pasighat, Arunachal Pradesh, during 2015 to 2016. The results showed that the genotypes exhibited marked variation in biochemical attributes. Among all the genotypes, highest ascorbic acid content (16.73 mg/100 g), total alkaloid (4.68 mg/100 g) and terpenoid content (3.23 mg/100g) was found in G-4. G-5 had highest total phenol (15.27 mg/100 g) and solasodine content (8.78 mg/100g). Highest steroid content (174.26 µg/100g) was observed in G-8. Maximum flavonoid content (13.58 mg/100g) was found in G-10 while highest phytosterol content (8.12%) was found in G-9. Hence, for medicinal purpose these genotypes were best suited for cultivation in different parts of NEH region.
