  • Several plant growth regulators were examined for on their effect on the in vitro propagation of Kalopanax pictus$(T_{HUNB}.)$ $(N_{AKAI}.)$ on WPM medium. Among the cytokinins tested, BA at $13.32\;{\mu}M$ appeared to be the most effective for multiple axillary shoot formation. Although the addition of $2.89\;{\mu}M\;GA_3$ promoted stem elongation, it produced morphologically abnormal leaves and stems. For rooting of the shoots, $4.9\;{\mu}M$ IBA seemed to be more effective than $2.69\;{\mu}M$ NAA. When the regenerated plants were transferred on artificial mixture containing vermiculite and peat-moss (1 : 1, v/v), 81% of them survived and grew normally.

  • The present study was to investigate the in vitro antioxidant potential of hot water extract and its fractions from dichloromethane ($CH_2Cl_2$), ethyl acetate (EtOAc), n-butanol (n-BuOH), and water ($H_2O$) of castor-aralia (Kalopanax pictus) leaves using different antioxidant tests. Among these crude extract and fractions, EtOAc fraction exhibited higher antioxidant potency than others in 1,1-diphenyl-2-pricylhydrazyl (DPPH) free radical scavenging, reducing power assay, and reactive oxygen species (ROS) scavenging activity. However, $CH_2Cl_2$ fraction showed higher hydroxyl radical scavenging and DNA damage protective activity. This work demonstrates the potential of castor-aralia leaves as antioxidant functional food ingredients.

  • An experiment was conducted to examine the effects of Kalopanax pictus Nakai (Kalopanax) on in vitro rumen fermentation and methane (CH4) reduction. Kalopanax trunk was extracted with 70% ethanol and 70% methanol. Rumen fluid, alfalfa hay and buffer (control: C) supplemented with 0.3% Kalopanx juice (T1), 0.3% ethanol extract (T2) and 0.3% methanol extract (T3) in the total volume of culture medium were incubated at $38^{\circ}C$ for 24h and 48h. Rumen pH was lower in all Kalopanax treatments during all incubations than that in control (p<0.05). Total VFA and total gas production in T2 and T3 was significantly higher than that in C at 48h incubation (p<0.05). Ammonia-N was decreased in all treatments compared with C during the incubation periods (p<0.05). At 24h incubation, $CH_4$ contents were significantly reduced by both alcohol extracts. It is concluded that supplementing Kalopanax extracts can stimulate ruminal fermentation of rumen microorganisms and inhibit methanogenesis.

  • 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.

  • This study was carried out to investigate the food value of K. pictus sprouts. The total ginsenoside content was 67.4 mg/kg. Including Ginsenoside Rg1, a total of five different types were detected by the experiment. The total phenol content was 33.77 mg/100 g. Including seven different type of essential amino acids, the total amino acid content of K. pictus sprouts was 33,744 mg/100 g. The results of the analysis of the free amino acid content showed that the total bitterness was much higher than the total sweetness. From the above results, the food characteristics of K. pictus sprouts could be determined. To improve their consumption, their bitterness must be reduced.

  • It was observed that the hot-water extract of the bark of Kalopanax pictus N. had the highest anti-complementary activity among the 11 kinds of forest materials. Methanol-and ethanol-soluble portions had low anti-complementary activities, but crude polysaccharide. HKP-0 had a high activity of 80%. HKP-0 contained 54.8% of total sugar and 27.9% of protein. The neutral sugars of HKP-0 consisted of mainly arabinose, galactose and glucose. HKP-4 fraction obtained by cetavlon treatment of HKP-0 showed the highest anti-complementary activity of 90%. The activity was not changed by pronase digestion bu decreased greatly by periodate oxidation. HKP-4 consisted of mainly arabinose and glucose with molar ratio of 1.0 : 22.4, HKP-4-I, an unabsorbed fraction from HKP-4 on DEAE Sepharose CL-6B column showed higher yield and activity than those of absorbed fractions. HKP-4-I was homogeneous, and its molecular weight was about 25,000. HKP-4-I contained 84.0% of neutral sugar and consisted of arabinose and glucose with molar ratio of 1.0 : 11.2. The anti-complementary activity of HKP-4-I was not decreased by the treatment of polymyxin B, and the polysaccharide activated both classical and alternative pathway in complement system. Void volume fraction obtained from HKP-4-I hydrolyzed with ${\alpha}$-amylase on Sephadex G-25 column only had a high anti-complementary activity.

  • Kalopanax pictus was cultured in vitro to find out optimal condition for embryogenic cells proliferation in liquid media rapidly. Embryogenic cells were induced from leaves and petiols of Kalopanax pictus. Optimum culture medium appeared to be a 1/2MS medium supplemented with 2.0mg/L 2,4-D and 0.1mg/L BA. To find out optimal conditions, embryogenic cells were cultured some condition as different concentrations of 2,4-D, medium and sucrose. There was cultured on 1/2MS liquid medium containing different concentration of 2,4-D. When embryogenic cells were cultured on 1/2MS liquid medium supplemented with 1.0mg/L 2,4-D, cell propagation rate was higher than other concentration of 2,4-D. When embryogenic cells were cultured on different media that MS, Gambols B5, N6, White, SH medium, observed the highest multiplication rate among Gambols B5 and White medium. To find out of effect of sucrose to embryogenic cells propagation, we tested cells under different concentrations. Optimal concentration of sucrose appeared to be a basal medium added 3% sucrose. Above results suggest that optimal conditions for proliferation of embryogenic cells were established Gambols B5 and White medium added 1.0mg/L 2,4-D and 3% sucrose. There is every possibility achieving embryogenic cells proliferation via bioreactor culture system in Kalopanax pictus.

  • The objective of this study was to evaluate the effect of fermented Kalopanax pictus (KP-F) on macrophage activation and its effect as a competitive inhibitor of LPS and inhibitory effect on endotoxemia. The results showed that KP-F could activate macrophage in a dose-dependent manner, and KP-F was confirmed to act as a ligand for TLR4. Also, it was found that KP-F did not exhibit the same biotoxicity as LPS in intraperitoneal injection, and that it could suppress the neutrophil migration induced by LPS administration. In normal mice, the body weight, tissue weight, and amount of nitrite and pro-inflammatory cytokines in serum showed no significant changes with KP-F diet for 2 weeks, confirming that administration of KP-F in normal mice did not lead to over activation of immune response and biotoxicity. In the mouse model of endotoxemia induced by LPS and D-galactosamine(D-GalN) in sub-lethal dose, the diet of KP-F effectively inhibited the amount of nitrite and cytokines in the blood, and thus was found to be able to relieve the hepatic and kidney injury. In addition, in the endotoxemia mouse model induced by LPS and D-GalN of lethal dose, the survival rate was increased by KP-F diet in a dose-dependent manner.

  • 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.
