Chemical Composition and Antidiabetic Activity of Essential Oils Obtained from Two Spices (Syzygium aromaticum and Cuminum cyminum)
The current aim was to evaluate antidiabetic potential of Syzygium aromaticum and Cuminum cyminum essential oils and their emulsions by alpha amylase inhibition assay. Antidiabetic activity of C. cyminum and S. aromaticum was examined in dose dependent mode (1 to 100 ug/mL) The maximum antidiabetic activity for S. aromaticum and C. cyminum essential oils was noted at the highest dose (100 ug/mL) Five emulsions (essential oil surfactant [tween 80] co surfactant [ethanol] water) of different concentrations for S. aromaticum (A1 to A5) and C. cyminum (B1 to B5) essential oils were formulated. Among different emulsions, A5 of S. aromaticum and B5 of C. cyminum essential oil exhibited a maximum antidiabetic activity with 95.30 and 83.09% inhibition of a amylase, respectively. Moreover, the analysis of essential oils showed that eugenol (18.7% and a pinene (18.8% were the major components of S. aromaticum and C. cyminum essential oils, respectively.
