The aim of this work was a chemical and biological characterisation of Fagiolina del Trasimeno (Italian cowpea landrace) in its coloured and white variants. After opening the package (T-0), samples were addressed to a set of chemical and biological assays. Analyses were also conducted on cooked, 6-month-stored (T-1) and commercial products. Chemical composition was comparatively analysed by nuclear magnetic resonance (NMR) of the proton. At both T-0 and T-1, raw coloured Fagiolina del Trasimeno showed statistically higher values in terms of phenolic content (T-0: 11.51 mg GAE/g, T-1: 9.34 mg GAE/g) and antioxidant activity (DPPH T-0: 27.40 mu mol TE/g, T-1: 20.15 mu mol TE/g; ABTS T-0: 37.98 mu mol CE/g, T-1: 27.24 mu mol CE/g) when compared with white/commercial variants. Globally, boiling, pressure-cooking, and storage led to a loss in phenolic content and antioxidant activity. However, values in coloured samples generally remained higher than those observed in the other products. Finally, Fagiolina del Trasimeno extracts were shown to inhibit cyclooxygenase activity in HepG2 cells (up to -41.96%).

Abstract

The aim of this work was a chemical and biological characterisation of Fagiolina del Trasimeno (Italian cowpea landrace) in its coloured and white variants. After opening the package (T-0), samples were addressed to a set of chemical and biological assays. Analyses were also conducted on cooked, 6-month-stored (T-1) and commercial products. Chemical composition was comparatively analysed by nuclear magnetic resonance (NMR) of the proton. At both T-0 and T-1, raw coloured Fagiolina del Trasimeno showed statistically higher values in terms of phenolic content (T-0: 11.51 mg GAE/g, T-1: 9.34 mg GAE/g) and antioxidant activity (DPPH T-0: 27.40 mu mol TE/g, T-1: 20.15 mu mol TE/g; ABTS T-0: 37.98 mu mol CE/g, T-1: 27.24 mu mol CE/g) when compared with white/commercial variants. Globally, boiling, pressure-cooking, and storage led to a loss in phenolic content and antioxidant activity. However, values in coloured samples generally remained higher than those observed in the other products. Finally, Fagiolina del Trasimeno extracts were shown to inhibit cyclooxygenase activity in HepG2 cells (up to -41.96%). In summary, these results highlighted interesting chemical and biological features of this product, showing the impact of routine procedures, as well.
