บทคัดย่อ (EN): Dried A. paniculata leaves from cabinet dryer (CAD) at 45°C, heat pump dryer (HPD) at 30°C and freeze dryer (FD) were used in storage experiment. Total phenolics content (TPC), total antioxidant activities (AOA), andrographolide and neoandrographolide content were found to decrease with increase in storage time and temperature in all samples. The degradation of TPC, AOA, andrographolide and neoandrographolide in dried A. paniculata leaves during storage followed the first-order equation with respect to temperature. The results showed an increase in the kinetic constant (k) with the increase of temperature. Half-life correlated with time at which the bioactive compounds were decreased by 50% with respect to time zero. The half-life (t1/2) of andrographolide and neoandrographolide of dried A. paniculata leaves in different drying methods and stored at 25°C was higher than of those stored at 35°C. The activation energy of major compounds in CAD, HPD and FD dried A. paniculata leaves was 5.85, 5.94 and 7.51 kJ/mol, for andrographolide and 6.28, 14.10 and 15.40 kJ/mol, for neoandrographolide, respectively. Dried A. paniculata packed in PET/Al/PE foil bags at 25°C preserved most of the bioactive compounds.
