High performance liquid chromatography (HPLC) and
mass spectrometric analyses were employed to determine the metabolite profile of tea including the concentrations
of artemisinin (47.5±0.8 mg L-1), dihydroartemisinic acid (70.0±0.3 mg L-1), arteannuin B (1.3±0.0 mg L-1), isovitexin
(105.0±7.2 mg L-1) and a range of polyphenolic acids
