Abstract
The present study deals with the investigation of erstwhile undocumented fifty four samples of West Bengal honey from ten different floral origins sesame (Sesamum indicum), hizal (Barringtonia acutangula), mustard (Brassica spp.), drumstick (Moringa oleifera), litchi (Litchi chinensis), eucalyptus (Eucalyptus spp.), karanza (Pongamia glabra), khalsi (Aegiceras corniculatum), goran (Ceriops decandra) and bain (Avicennia officinalis) for its quantification and comparison of antioxidative capacity by chemometrics. The average total polyphenol and flavonoid content of honeys varied from 9.9 ± 0.6 (bain) to 44.7 ± 2 mg (hizal) gallic acid equivalent and 5.12 ± 0.23 (drumstick) to 19.4 ± 1.38 (bain) mg of quercetin per 100 g respectively. Dark brown hizal honey with ABS450 value of 2055.6 mAU exhibited the most potent DPPH (2, 2-diphenyl-1picrylhydrazyl) radical scavenger (IC50 = 23.92 ± 1.12 mg/mL) and a FRAP (ferric reducing ability of plasma) value of 381 ± 1.9μM Fe (II).
