Interpretive Summary: Resveratrol, a polyphenolic compound uniquely identified in plants greatly contributes to human health. trans-Resveratrol has antioxidative, anti-inflammatory, anticancer activities as well as chemopreventive, cardioprotective, and estrogenic effects. Just like grapes or wines, peanut seeds contain resveratrol. The resveratrol amounts in the peanut seeds were quantified by high performance liquid chromatography (HPLC). trans-Resveratrol content in fresh raw peanut seeds was on average about 0.5 ug/g and a statistically significant variation (from 0.125 ug/g to 1.626 ug/g, at least a ten times difference) was detected among the accessions analyzed. The average weight for 100 seeds was 52.84 g. A statistically significant variation in seed weight (from 22.30 g to 87.94 g) was observed. There was no significant correlation between trans-resveratrol content and seed weight. The information about the levels of trans-resveratrol in peanut seeds will be useful for peanut cultivar development and peanut product processing. Breeders can use germplasm accessions containing a high amount of resveratrol to develop new peanut cultivars and food processers can take the new cultivars to manufacture high resveratrol peanut products (for example, butters and crackers).

Technical Abstract: trans-Resveratrol (trans-3,5,4'-trihydroxystilbene), a polyphenolic compound uniquely identified in plants greatly contributes to human health. Peanut (Arachis hypogaea L.) seeds of 20 germplasm accessions were harvested from the same field and used for resveratrol analysis by high performance liquid chromatography (HPLC). trans-Resveratrol content in fresh raw peanut seeds was on average about 0.5 ug/g and a statistically significant variation (from 0.125 ug/g to 1.626 ug/g, at least a ten times difference) was detected among the accessions analyzed. The average weight for 100 seeds was 52.84 g. A statistically significant variation in seed weight (from 22.30 g to 87.94 g, at least a four times difference) was observed. There was no significant correlation between trans-resveratrol content and seed weight. The information about the levels of trans-resveratrol in peanut seeds will be useful for peanut cultivar development and peanut product processing. Breeders can use germplasm accessions containing a high amount of resveratrol to develop new peanut cultivars and food processers can take the new cultivars to manufacture high resveratrol peanut products.
