The objective of this study was to investigate some nutritional and antioxidant parameters of six different peanut genotypes grown in Turkey. Unshelled seed extracts were used for analyses. The skins of the seeds were not peeled. The crude protein and the crude oil amounts, fatty acid compositions, the total phenolic and flavonoid contents and the total antioxidant capacities were investigated. The crude oil contents of seeds ranged from 43.9 to 45.9%. On the other hand, the crude protein
... crude protein contents varied between 26.9 and 30.6%. The highest protein percentage was determined in NC-7 seeds. The crude oil contents of the genotypes were not different statistically. Oleic acid was the most plentiful fatty acid in all genotypes and followed by linoleic acid, palmitic, stearic and linolenic acids, respectively. The highest oleic acid/linoleic acid ratio was found in NC-7 and DA35/2011. Data obtained from the total phenolic and the total flavonoid analyses had similar manners for each genotype. NC-7 and DA35-2011 were the poorest genotypes in the total phenolic and flavonoid levels. With regards to the ABTS .+ radical scavenging activity, the most powerful genotypes were Gazipaşa and Sultan. Our study showed that the more phenolic content gave rise to the more antioxidant capacity for each genotype.
