The Pogostemon cablin Benth(PCB) and Eupatorium fortunei Turez(EFT) belong to the groups of complex prescription " Yu-Geng-Tong-Yu decoction". The separation of the effective component was taken by n-hexane
chlorofrom
methanol and water respectively
and the Ca2+ antagonistic effect was determined by 45Ca transmembrane influx technique. It was found that the extract separated by silica gel chromatography and eluted by n-hexane have seven functional fractions. Among them
the dark-green fraction of PCB and the orange fraction of EFT have strongest activity of Ca2+ antagonistic effect.
