In vitroAntioxidant and Antidiabetic Activity of Regional Chemotypes of three Curcuma species from Chhattisgarh

Abstract

Phytoconstituents and nutritional rich Curcuma species playsan important role in medication. In the present study rhizomes of Curcuma longa, Curcuma caesia and Curcuma aromatica from different regions of Chhattisgarh, Indiawere chosen for best chemotype identification on the basis of antioxidant and antidiabetic potential. Curcuminoids found in Curcuma rhizomes vary often with varieties, locations, sources, and cultivation conditions, while there are significant variations in varieties and geographical locations as well as its genetic makeup. Chemotypic variations were found in regional samples and they showed varying antioxidant and antidiabetic property. Samples collected from Sarguja district showed highest antioxidant potential in most of the invitro assay. Sarguja samples of C.aromatica and C.longa showed much more similar antioxidant activity (EC₅₀ in µg) as ferric reducing antioxidant property (~56.33 ± 0.54), ABTS (~51.06 ± 0.02) and super oxide scavenging (~0.61 ± 0.02) activity. C.caesia extracts of all the regions revealed high antidiabetic activity as compared to other two species and its percent inhibition range was from 79.40 to 84.59. All the values were compared by standard curcumin and showed significant variation region wise.
