Such as several plants, Pines are known to have anti-diabetic potential. The current study evaluated the anti-diabetic potential of Pinus nigra essential oils, obtained from nine Pinus nigra provenances planted in Northwestern Tunisia, via in vitro inhibition of α-amylase. The α-amylase inhibitory potentials were determined using radial diffusion method. Our results showed a significant difference between provenances. The α-amylase inhibitory potential ranged from 10% to 26.6%. The essential oils of Crimée provenance from Pinus nigra
pallasiana subsp. displayed the most effective inhibition of α amylase. While, essential oils of Bois frerot provenance from Pinus nigra laricio subsp. showed the lowest inhibitory potential (10%). The observed inhibitions of α-amylase suggest that the essential oils of P. nigra of some provenances may be useful in the management of diabetes mellitus.
