Abstract: HighlightsA dereplication strategy using HPLC–QTOF‐MS is proposed.Two novel triterpenoid saponins are identified and purified from Celosiae Semen.Their structures are elucidated by spectroscopic and chemical analyses.Their hepatoprotectivities are evaluated. ABSTRACT Although natural products (NPs) from ethnomedical… read more here.
