Physicochemical and antioxidant properties of Indian monofloral honeys

Abstract

The present study deals with the investigation of erstwhile undocumented six samples of indian honey from six different floral origins - moringa (Moringa oleifera), wild Acacia (Robina pseudoacacia ), mustard (Brassica spp.), litchi (Litchi chinensis), jamun (Syzgium cumini), and solai (Plectoranthus Rugosus) for its quantification and comparison of antioxidative capacity by chemometrics. The average total polyphenol and flavonoid content of honeys varied from 10.6 ± 0.68 (moringa) to 35.4 ± 1.8 mg (lychee) gallic acid equivalent and 1.53 ± 0.38 (wild acacia) to 15.67 ± 0.83 (lychee) mg of quercetin per 100 g respectively. Dark brown jamun honey with ABS450 value of 2011.6 mAU exhibited the most potent DPPH (2, 2-diphenyl-1- picrylhydrazyl) radical scavenger (IC50 = 27.48 ± 0.48 mg/mL) and a FRAP (ferric reducing ability of plasma) value of 365 ±2.1 µM Fe (II)..
