Honey is used since ancient time as a food and to cure many diseases. The present study investigated the chem. constituents, antioxidant and enzyme inhibition activities of natural Saudi Sidr (SH) and Talh (TH) honeys. Beside entire honey samples, Et acetate, ethanol and water extracts were prepared The total polyphenolic content of SH, TH and their extracts was in the range of 2.86-7.21 and 3.80-17.33 mg gallic acid equivalent/g, resp. and the total flavonoids content was in the range of 0.05-1.17 and 0.18-2.38 mg rutin equivalent/g, resp. Out of the 53 standards analyzed by HPLC, 27 compounds were detected with highest number of compounds identified in the Et acetate extract of TH (45%, 24/53) and SH (26%, 14/53), resp. Quinic acid was dominant compound identified in all honey samples with the highest content determined in TH ethanol extract (4454μg/g). The majority of tested samples possessed considerable anti-radicals and reducing ions capacity with the Et acetate extract from TH exerted significantly (p<0.05) the highest activity. All honey samples did not show chelating iron metal property. Honey samples revealed variable enzyme inhibition activity with TH (entire and/or Et acetate extract) showed significantly (p<0.05) the highest acetylcholinesterase, butyrylcholinesterase, tyrosinase and α-amylase inhibition activity. In conclusion, Et acetate is the best solvent for extraction of bioactive mols. from the two honey types. Moreover, the dark-colored TH contained the highest number of mols. and consequently exerted the best antioxidant and enzyme inhibition activities in most assays.
