The invention relates to a method for extracting liensinine, isoliensinine and neferine from lotus plumule, which adopts the lotus plumule as a raw material and comprises the following steps of: (1) preparing a crude extract; (2) preseparating by adopting macroporous resin; (3) purifying by adopting a high speed counter current chromatography to obtain the liensinine, the isoliensinine and the neferine with the purity of more than 98 percent. By extracting alkaloid in a lotus plumule medicinal material by adopting ethanol, carrying out preseparation by adopting macroporous resin, adopting the ethanol as an eluant and carrying out purification by adopting the high speed counter current chromatography, the process is environmental-friendly without serious damage to the environment.
