【 摘 要 】

The purpose of this research are to recovery of pancreatic lipase inhibitor and to study the effect of using different concentration of substrate and reaction time on pancreatic lipase inhibitor. In this research, Aquilaria subintegra mature and fresh leaves was used as a sample. The research was conducted by using hydro-distillation with different concentrations, which are 100 μM, 200 μM and 300 μM and reaction times from 20, 40 and 60 minutes were studied. Based on the results obtained for the samples of phenol, flavonoid, gallic acid and quercetin were 49.30 μg/ml, 314.33 μg/ml, 12.94 μg/ml, and 5.15 μg/ml, respectively.
