Abstract��
OBJECTIVE To extract corilagin and its analogs from Phyllanthus urinaria L. by corilagin-molecularly imprinted polymer��Cor-MIP��. METHODS The Cor-MIP was loaded into the cartridges of solid-phase extraction column (MISPE). The MISPE was used for extracting corilagin and its analogs from Phyllanthus urinaria L.. The samples were measured by mass spectrometry (MS). RESULTS Cor-MIP showed good selectivity and extracted corilagin and geraniin from Phyllanthus urinaria L.. CONCLUSION The corilagin-MIP has good selectivity for corilagin and it can be used for extracting and concentrating corilagin and its analogs from herbs.
