    • Irradiation was carried out at ambient temperature, using a cobalt-60 irradiator (point source AECL, IR-79, MDS Nordion International Co. Ltd, Ottawa, ON, Canada) in the Advanced Radiation Technology Institute, Korea Atomic Energy Research Institute (Jeongup, Korea). The source strength was approximately 320 kCi, with dose rate at the location of the sample of 10 kGy/h. Dosimetry was performed using 5 mm diameter alanine dosimeters (Bruker Instruments, Rheinstetten, Germany). The dosimeters were calibrated against an International Standard Set by the International Atomic Energy Agency (Vienna, Austria). Sample solution (2 g curcumin in 200 mL MeOH) in chapped vials were irradiated with 30 kGy (absorbed dose). The irradiated methanolic solution was immediately evaporated to remove the solvent and lyophilized

    • 2, pH 7.0). Then, 100 μL of the compounds at the test concentration or orlistat (Roche, Basel, Switzerland) was mixed with 880 μL of the enzyme-buffer, and incubated for 15 min at 37 °C, with 20 μL of the substrate solution [10 mM p-NPB (p-nitrophenylbutyrate) in dimethyl formamide] added and the enzymatic reactions allowed to proceed for 15 min at 37 °C. The pancreatic lipase activity was determined by measuring the hydrolysis of p-NPB to p-nitrophenol at 405 nm using an ELISA reader (Tecan, Infinite F200, Austria). Inhibition of the lipase activity was expressed as the percentage decrease in the OD when porcine pancreatic lipase was incubated with the test compounds.
