Antifungal activities of the compounds isolated from Kalopanax pictus against representative fungi of dermatomycosis were investigated using paper disc diffusion method. It was found that kalopanaxsaponins A and I were effective in inhibiting the growth of Candida albicans KCTC 1940 and Cryptococcus neoformans KCTC 7224 with minimum inhibitory concentration(MIC) of 25${\mu}g$/ml. It showed that antifungal activity of both compounds have strong selectivity against the fungi of dermatomycosis.

Hepatic lipid peroxide contents were examined in bromobenzene-treated rats firstly after the oral administration of MeOH extract of Kalopanax pictus stem bark its n-BuOH fraction, EtOAc fraction and an alkaline hydrolysate of the n-BuOH fraction, and secondly after the intraperitoneal administration of hederagenin monodesmosides and bisdesmosides. Two hederagenin monodesmosides, kalopanaxsaponin A (KPS-A) and sapindoside C, exhibited significant anti-lipid peroxidation effects after intraperitoneal administration at doses of $10-30{\;}{\mu}mole/kg$, whereas their bisdesmosides did not exhibit any significant activity. These results suggest that it is the hederagenin monodesmosides that are responsible for anti-lipid peroxidation in vivo. The activity of KPS-A was established by the observation of decreased aminopyrine N-demethylase activity and increased epoxide hydrolase activity.

The three crude drugs of the Kalopanax pictus (Araliaceae) roots (K), Pueraria thunbergiana (Leguminosae) flowers (P), and the Rhus verniciflua (Anacardiaceae) heartwood(R) used for anti-thirst drugs in Oriental herb medicine were extracted with MeOH, respectively, and the successive fractionation of the extract gave EtOAc extract. Certain amount ratios of the three extracts were also prepared to compare the antimutagenicity in Ames test. In N-methyl-N(-nitro-N-nitrosoguanidine (MNNG; 0.4 (g/plate)-induced test, the activities of complex mixture were observed between the highest antimutagenic activity of K extract and the lowest P extract. In aflatoxin (AFB$_1$)-induced test, the EtOAc complex (K : P : R=l : 1 : 3) labeled E-113 decreased the revertants of Salmonella typhimurium TA100 by 95％, which activity were highest among other extracts or complexes mixture used. Fractionation of organic solvent mostly increased the antimutagenicity. These trends were also observed in the antimutagenicity test of the mixture of each active component of kalopanaxsaponin A, tectorigenin and sulfuretin. These results supported that many kinds of anti-thirst herb medicine in the prescription could effectively prevent cancer disease.
