Estimation of Total Bioactive Compounds in Pigmented and Non Pigmented Genotypes of Sorghum (Sorghum bicolor (L.) Moench)

Abstract

Sorghum seed contains unique bioactive compounds on par with other cereals. Bioactive compounds in plants can be defined as secondary plant metabolites. The secondary bioactive compounds in plants appear to be randomly synthesized but they are not useless junk. They can be used as anantimicrobial, antioxidant, and anti-inflammatory activity. Hence, In the present study, we have investigated to estimate the total bioactive compounds in selected genotypes by using spectrophotometer to quantitative and qualitative assay on six different genotypes including non pigmented (IS 3477, IS 33095, IS 7005) pigmented (IS 2898, IS 7155, IS 1202). The range of bioactive compounds between the pigmented and non pigmented genotypes detected high amount of total Polyphenols, Tannins, Flavonoids, Carotenoids and Anthocyaninsi.e.,40.33 ± 0.98-96.24 ± 1.97 mg GAE/100 gm, 26.61 ± 1.00-88.42 ± 1.89 mg TAE/100 gm, 2.16 ± 0.15- 8.48 ± 0.16mg QUE/100 gm, 2.35 ± 0.10-21.20 ± 0.38 β-CAE/100 gm, 2.31 ± 0.22-8.49 ± 0.52C-3-G mg/100 gm respectively. Among the genotypes, pigmented genotypes showed high levels of bioactive compounds than non pigmented genotypes.
