AI Article Synopsis
- Jatropha curcas seed shells, a by-product of oil extraction, have gained attention for their chemical properties and potential uses.
- The study identified and quantified various phenolic compounds in the shells, finding high levels of free, conjugate, and bound phenolics.
- The methanolic extract from these shells demonstrated significant antioxidant activity, comparable to well-known antioxidants like Trolox and ascorbic acid, making it a promising source of natural antioxidants.
Article Abstract
Jatropha curcas seed shells are the by-product obtained during oil extraction process. Recently, its chemical composition has gained attention since its potential applications. The aim of this study was to identify phenolic compounds profile from a non-toxic J. curcas shell from Mexico, besides, evaluate J. curcas shell methanolic extract (JcSME) antioxidant activity. Free, conjugate and bound phenolics were fractionated and quantified (606.7, 193.32 and 909.59 μg/g shell, respectively) and 13 individual phenolic compounds were detected by HPLC. The radical-scavenging activity of JcSME was similar to Trolox and ascorbic acid by DPPH assay while by ABTS assay it was similar to BHT. Effective antioxidant capacity by ORAC was found (426.44 ± 53.39 μmol Trolox equivalents/g shell). The Mexican non-toxic J. curcas shell is rich in phenolic compounds with high antioxidant activity; hence, it could be considerate as a good source of natural antioxidants.
