For the quality control of Kalopanacis Cortex, saponin compound, kalopanax-saponin B was isolated from the MeOH extract of Kalopanacis Cortex, and identified by the spectroscopic evidences. A quantitative analysis of kalopanaxsapo-nits B using HPLC method showed that the average contents was $1.010{\pm}0.212%$, respectively, in 22 samples collected through-out the regions of Korea.

In this study, we established the optimal conditions for obtaining water-soluble extracts with antioxidant activity from Kalopanacis cortex. The extraction conditions tested included cold treatment, extraction time (1, 5, 10, 15, and 24 h), and extraction temperature (55, 75, and $95^{\circ}C$). The highest total polyphenol compound content from water soluble extracts ($612{\mu}g/mL$) was obtained at $95^{\circ}C$ for 15 h after cold treatment. The 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenger activity was also highest (78.8%) under these conditions, which was comparable to 70.2% of ascorbic acid. The hydroxyl radical scavenging activity (HRSA) was also highest (69.0%) under these conditions, stronger than 56.6% of ascorbic acid. These results may provide critical evidence supporting the use of Kalopanacis cortex as a source of antioxidants in functional foods.

This study was performed to determine the antimutagenic and cytotoxic effect of ,Kalopanacis cortex endothelium. Methanol extract was used on Salmonella typhimurium TA98, TA100 and three cancer cell lines. In the Ames test, methanol extract of Kalopanacis cortex endothelium alone did not exhibit any mutagenicity but showed substantial inhibitory effects against mutation induced by 4-nitroquinoline-l-oxide(4NQO), N'-methyl- N'-nitro-N-nitrosoguanidine(MNNG) and benzo(a)pyrene(B(a)P). The methanol extract of Kalopanacis cortex endothelium showed approximately 79.29% and 75.38% inhibitory effect on the mutagenesis induced by 4NQO and B(a)P, respectively, against TA98 strain. Whereas 79.49%, 89.3% and 68.85% inhibitions were observed on the mutagenesis induced by 4NQO, MNNG and B(a)P against TA100 strain. Methanol extracts from Kalopanacis cortex endothelium showed high antimutagenic effects against 4NQO, MNNG and B(a)P. The anticancer effects of methanol extract from Kalopanacis cortex endothelium against human lung carcinoma(A549), human breast adenocarcinoma (MCF-7) and human hepatocellular carcinoma(Hep3B) were investigated. The treatment of 0.5mg/ml Kalopanacis cortex endothelium methanol extracts had the highest cytotoxicity against A549(81.54%), followed by MCF-7(81.92%) and Hep3B (78.57%). In contrast 0.5mg/ml treatment of methanol extracts from Kalopanacis cortex endothelium had only $4{\sim}25%$ cytotoxicity on normal human liver cell(293).

The study on phytochemical analysis and the biological activity of Kalopanacis Cortex was carried out in this research. As a phytochemical result, liriodendrin as a lignan glycoside was isolated and characterized. Two subfraction separated from the acidic substance of $CHCl_3$ fraction were saturated and unsaturated fatty acid, respectively. Saturated fatty acid mixture identified from GC-MS tool was as follows: palmitic acid, stearic acid, arachidic acid, heneicosanoic acid, docosanoic acid, tricosanoic acid, tetracosanoic acid, pentacosanoic acid, hexacosanoic acid and octacosanoic acid. Unsaturated fatty acid was found to be linoleic acid on the basis of spectroscopic method. An active principle of liriodendrin exhibited significant antihepatotoxic activity but failed to show a considerable antiedemic activity. In this paper, the result of writhing test on liriodendrin was also described.

To develop a clinically available saponin- or sapogenin complex from Oriental medicines, the EtOH extract (KPRG-A) was obtained by extracting from the four crude drugs, Kalopanacis Cortex, Platycodi Radix, Rubi Fructus and Glycyrrhizae Radis. The BuOH fraction (KPRG-B), a crude saponin complex, was prepared by fractionating KPRG-A, which were further completely hydrolyzed to afford the sapogenin complex (KPRG-D). In an attempt to find the antinoicpetive effects of the saponin complex and sapogenin complex, KPRG-C, and -D, were assayed by writhing-, hot plate-, and tail-flick tests using mice or rats. The three samples were also subjected to antiiflammatory tests using serotonin-induced and carrageenan-induced hind paw edema mice and rats, respectively. The three samples significantly reduced inflammations and pains of the experimental animal. The potency were found in the order of KPRG-D> KPRG-C> KPRG-B. The most active sample, KPRG-D, caused no death, no body increase or no anatomical pathlogic change even at 2,000 mg/kg dose. These results suggest that a sapogenin complex, KPRG-D, which was found to contain mainly hederagenin, platycodigenin, polygalacic acid, 23-hydroxytormentic acid, glycyrrhetic acid together with minor triterpene acids, could be a potential candidate for antiinflammatory therapeutics.
