An effective method was developed for the preparative separation and purification of monoterpenoid indole alkaloid epimers from Ervatamia yunnanensis Tsiang using a combination of pH-zone-refining counter-current chromatography and preparative high-performance liquid chromatography. With this method, two pairs of MIA epimers including ervatamine (72 mg, 1), 20-epi-ervatamine (27 mg, 4), dregamine (95 mg, 2), tabernaemontanine (129 mg, 3), along with two MIAs, apparicine (112 mg, 5) and isovoacangine (15 mg, 6), were successfully purified from 2.1 g crude extract of E. yunnanensis, each with a purity of over 95% as determined by HPLC. The structures of the MIAs were identified by ESI-MS, 1D, and 2D NMR.
