Abstract

To find the monthly variation of kalopanaxsaponin contents in the leaves of Kalopanax pictus with thorns (KPT) and with no thorns (KPN), the leaves monthly collected from May to September were extracted with MeOH and then the kalopanaksaponin fractions were prepared. KPT collected on May showed the lowest saponin content of the KPTs whereas KPT on August exhibited the highest saponin content. From September, the saponin content in the loaves decreased. The highest saponin content was shown to be 7.3% in KPN collected on August. Evaluation of six kalopanaxsaponins A, I, J, B, H and K (KPA, KPI, KPJ, KPB, KPH, and KPK) were performed using TLC densitometer. In this measurement, considerably higher KPB and KPH, both hederagenin bisdesmosides, were found whereas very low contents In monodesrnosides KPI and KPJ were observed. In conclusion, it was shown that the leaves of KPN of August could be a biomaterial source for the kalopanaxsaponin fraction. It was also suggested that measurement of the weight of kalopanaxsaponin fraction and the content of KPB as the representative compound for kalopanaxsaponins will be used for the quantitative evaluation of the kalopanaxsaponins of K. pictus.
