Synergistic Effect of Pericarp of Mangosteen and Propolis from Stingless Bee Extracts on Nitric Oxide Scavenging Activity

The aim of this research is to study the synergistic effect on nitric oxide scavenging activity mangosteen pericarp and stingless bee (Tetragonula laviceps) propolis extracts their phytochemical constituents. were extracted by reflux method with ethanol. TPC TFC extract 123.73±2.80 mg GAE/g 70.65±11.21 QE/g extract, respectively, was 387.93±15.10 87.00±5.06 respectively. ESI-LC-MS data displayed that both have a variety constituents, such as xanthones, flavonoids, miscellaneous. Nitric activities showed higher than individual various concentrations. Thus, may be an alternative source inflammatory drug development in future.
