| Abstract | Centotheca lappacea (L.) Desv. or โhee yumโ grass has been used in Thailand for postpartum care. This study focusedon analyses of elements, antioxidants and volatile compounds from C. lappacea. Wavelength dispersive X-ray fluorescenceshowed the presence of silicon in this plant. Liquid chromatographyโ"electrospray ionization-quadrupole-time of flight-massspectrometer coupled with DPPH assay was used for separation, detection and identification of antioxidants in C. lappacea inone run. Twelve antioxidants including C-and O-glycosides of luteolin and apigenin were identified. Moreover, a headspace gaschromatography-mass spectrometer was used for analyses of volatile compounds by direct burning of the plant material, which issimilar to how smoke is made during a traditional treatment. Nineteen and twenty-five compounds were found from the roots andthe aerial parts of C. lappacea, respectively. In conclusion, antioxidants and volatile constituents after C. lappacea has been burntare reported here for the first time. |
