Methods: A crude extract of the medicinally important Apiaceae (Centella asiatica) was purified by column chromatography. The purified compound was then analyzed by liquid chromatography-mass spectrometer (LCMS). The mass of the bioactive compound of Centella asiatica was detected using spectroscopic data.
Results: The mass spectrometric data derived by this method was sufficient for the identification and characterization of the bioactive component. The main ion m/z 488 corresponds to asiatic acid.
Conclusion: LCMS allows for a rapid and accurate measure of the active component asiatic acid in Centella asiatica, thereby providing a typical finger-print of the examined plant.
