Abstract
The HSCCC was successfully interfaced with a mass spectrometer possessing APCI‐ and ESI‐MS mode for the first time. The coupling system gave an excellent separation of ethyl acetate extract from the seeds of O. indicum using a solvent system composed of hexane‐ethyl acetate‐methanol‐0.2% formic acid (1:1.2:1:1); the online data of APCI‐MS and APCI‐MS‐MS provided useful information for the identification of the compounds.
