title: Assessment of phytochemical composition and antioxidant potential in some indigenous chilli genotypes from North East India.
abstract: Twenty five chilli genotypes from North East region of India evaluated showed variation for capsaicin from 0.27% (CHF-CA-1) to 3.03% (CHF-CA-21), oleoresin content from 2.49% (CHF-CA-5) to 9.26% (CHF-CA-18) with high to moderate ascorbic acid. Total phenolics ranged from 5.1 (CHF-CA-8) to 26.8 (CHF-CA-23) mg GAE/g and total carotenoids from 0.09 (CHF-CA-16) to 7.72 (CHF-CA-17) mg/g dry weight. The antioxidant activity varied from 15.3% (CHF-CA-4) to 60.7% (CHF-CA-21). Free radical scavenging activity using DPPH assay showed low IC50 ranging from 0.021 to 0.041 mg/mg, low EC50 from 0.92 to 1.78 mg/mg DPPH, high ARP values (56.17-109.52) in CHF-CA-6, CHF-CA-7, CHF-CA-17, CHF-CA-21, CHF-CA-22 and CHF-CA-23 genotypes. The reducing power ranged from 0.92 to 4.10 ASE/ml and specific phenolic composition showed presence of gallic acid with other hydroxycinnamic acid. Among the flavonoids, presence of catechin was maximum followed by quercetin and rutin.
