This study identifies the bioactive con.stituents present in two South African plant species Scabiosa columbaria and Sclerocarya birrea using bioassay guided fractionation method.
Supplementary data 1-6 shows the MS and MS/MS data obtained for compounds tentatively identified from the acetone extract of the leaves of S. columbaria. This was achieved on a Waters acquity ultraperformance liquid chromatography quadrupole time of flight mass spectrometer (UPLC-QTOF-MS). The compounds were tentatively identified by obtaining the molecular formular of compounds from Masslynx based on the best iFit value, mass error and %Fit Conf comparing their MS/MS fragmentation pattern with that of the best suggested matched compounds from Chem Spider, Metfrag, Metlin, Metfusion, Dictionary of Natural Products, PubChem and water UNIFY Scientific Information System(version 1.9.2) assessing the Chinese Natural Product database. Additionally, known compounds reported in the genus or plant species were identified by comparing their accurate masses and fragments although this might not be able to distinguish between isomers.
