Abstract
Secondary metabolites are extensively distributed among several plant species serve’s up as a precious reward of nature having marked effectiveness against oxidative stresses of physiological pathways in our body divisions. The present analysis was based on exploration of natural essentials of sunflower (Helianthus annuus L.) i.e. antioxidants, Phenolic and flavonoids considering their dietary impacts by applying standards i.e. DPPH and Folin-Ciocalteu and to elucidate additional nutritional aspects of specie. The study was consisted on 25 hybrids of sunflower (Helianthus annuus L.) including two check hybrids i.e. Hysun-33 and NKS-278 frequently planted in fields per annum. The activity was investigated at two levels control (0-0%) and 100 % under laboratory conditions. The scavenging assay by comparing enzymatic inhibitory concentration at 50 % (IC 50) revealed significant (p<0.05) among hybrids i.e. SMH-0916, NKS-278, SMH-0925, SMH-1105, SH-K-6 and SMH-1019 can be suggested for future exceptional outcomes at commercial level while, non-enzymatic essentials i.e. flavonoid and Phenolic were recorded between 13.27 mg/g-35.47 mg/g and 34.50 mg/g-99 mg/g respectively. The other distinguishing attributes of specie include volatile oil, B vitamins (B1, B3 and B6), vitamin E, linoleic acid, high oleic acid, 47% fat, 20-30 % protein, Carbohydrates, Sugars, magnesium and also enriched with iron supplements more than any other crop specie.
