Turmeric (Curcuma longa L.) volatile oil inhibits key enzymes linked to type 2 diabetes

In this study, α-amylase and α-glucosidase inhibitory potentials of C. longa volatile oil were evaluated for the first time. As the dried turmeric rhizomes are preferentially stored, transported and used by consumers, the effects of drying of rhizome on antidiabetic effects of its essential oil were also studied.
