| Abstract | The purpose of this study was to investigate the effect of extraction conditions on the physical and antioxidant properties of Yanang (Tiliacora triandra) leaf extract. The studied extraction conditions were leaves to water ratio (1:6 and 1:9), blending speed (22,000 and 32,000 rpm), heating temperature (60, 70, and 80 ฐC), and heating time (1, 3, 6, 9, 12, and 15 min). The extracts were examined for physical (color and stability) and antioxidant total phenolic content (TPC), 2,2-diphyneyl-2-picryl-hydrazyl (DPPH) radical scavenging activity, and Xanthine oxidase inhibitory activity) properties. Delta E (?E*) decreased with an increase in ratio but it increased with increase blending speed. Increases in ratio, blending speed, and time lowered the stability, however, the temperature did not affect the stability. The antioxidant properties improved when the ratio and blending speed increased. Higher temperature and longer time declined the antioxidant properties of the extract. Results showed that the extraction conditions much affected antioxidant activity than physical properties. The degradation of TPC followed the zero-order reaction (R2 0.676-0.938) while the degradations of DPPH radical scavenging (R2 0.738-0.969) and Xanthine oxidase inhibitory (XOI) activities (R2 0.790-0.986) followed the second-order reaction. The most suitable extraction condition was the extraction using a 1:9 ratio, 32,000 rpm, 60oC, and 1 min. This study proposed the Arrhenius equation of TPC, DPPH radical scavenging activity, and XOI activity with a correlation coefficient of 0.792, 0.938, and 0.735, respectively. |
