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.

Morphological characteristics of Kalopanox pictus Nakai were studied to examine population differentiation of this species. Based on a phenogram of using 23 morphological characteristics, differentiation of regions were distinct. Collections of 138 specimens from nine populations served as operational taxonomic unit (OTU's) were examined for phenotypic similarity and morphological variation using clustering (Ward's minimum variance method) and principal component analysis (PCA). The first three principal components were responsible for 77.0% of the total variance. Principal component 1 explained 52% of the total variance and was contributed to by the number of palmately parted, the number of pinnately lobed, and width between two lateral lobe apex.

Terminal buds and young leaves of Kalopanax pictus are in a great demand as a edible vegetable. Its bark of stems and roots have been used as the resources of folk medicine in Korea. Recently, attempts to cultivate the plant have being tried in farms and mountain villages. This study was conducted to determine effect of inorganic elements on seedlings growth of K. pictus. Levels of inorganic elements in the leaves were variable based on macro and micro inorganic elements. Among the inorganic elements in the leaves of K. pictus seedlings, level of N was high, while other ions were low in the order of K, Ca, P, Mg, Mn, Fe and Zn. A highly significant correlations between the seedling growth and the level of N, P, K, and Na in the leaves, while a low positive significant correlations between the growth and the level of either Mg or Mn and no significant correlations between the growth and the level of Ca, Fe, Cu, and Zn. The most affecting inorganic ion on the seedling growth was N, and followed by the order of K, P, Mg, Mn and Na.

This study was to investigate the effect of the extract(KP-HE) from Kalopanax pictus(KP) fermented with Hericium erinaceum(HE) mycelium on oxidative modification of neurofilament-L(NF-L) which is closely related to neurodegenerative disorders. The oxidative modification of NF-L was induced by AAPH producing peroxyl radicals in solution, and KP, HE, and KP-HE was investigated. KP and HE did not protect NF-L against peroxyl radical-mediated NF-L modification whereas KP-HE significantly prevented NF-L modification induced by peroxyl radical. KP-HE inhibited the formation of dityrosine in oxidative modification of NF-L and stimulated the peroxyl radical scavenging activity. The effects of KP, HE, and KP-HE on the modification of NF-L by tetrahydropapaveroline(THP), a neurotoxin found in patients with Parkinson's disease was investigated. KP-HE also prevented THP-mediated NF-L modification as compared to KP and HE. In addition, KP-HE significantly inhibited the formation of dityrosine in oxidative modified NF-L and enhanced the inhibition of reactive oxygen species(ROS) was generated by THP. The results suggested that KP-HE can contribute to protected cell from oxidative stress was induced by ROS and neurotoxin. Therefore, KP-HE could potentially be used as a valuable functional food ingredient to prevent neurodegenerative disorders.

This study was purposed to elucidate the best optimum sites by ecophysiological response measurements of Kalopanax pictus samplings of plantation. The diurnal changes of the stomatal transpiration, water use efficiency, water potential, and intercellullar $CO_2$ concentration of leaves were measured by the portable IR $CO_2$ analyzer. The results obtained are summarized as follows. 1) The daily stomatal transpiration rate was highest at 10:00 a.m. After 16:00, the stomatal transpiration rate rapidly decreased. 2) The daily water use efficiency was maximum at 8:00 a.m., and then rapidly decreased until midday with decreasing water potential. 3) The daily $C_i/C_a$ ratio rapidly decreased until 9:00 a.m., and then showed a stable value until 16:00, and then rapidly increased. The daily intercellullar $CO_2$ concentration ($C_i/C_a$ ratio) showed the same tendency as water potential changes. Consequently, stomatal transpiration and water use efficiency was increased with high water potential of leaves at am, and then remarkably decreased with low water potential at pm.
