The pouches of the positive controls were treated with the solvent used to dissolve the flavonoids and the solution of the carcin...
Two types of monofloral Malaysian honey (Gelam and Nenas) were analyzed to determine their antioxidant activities and total phenolic and flavonoid contents, with and without gamma irradiation.
