POCER1914: Elucidation of Gallic Acid Degradation Pathway from Labisia Pumila via Mass Spectroscopy Technique

Thermal degradation kinetics and mechanism of gallic acid was investigated at temperatures ranging from 60 to 120 °C with a heating time of 90 min. The ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometer was used to elucidate the degradation mechanism of...
