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.

Aralia cordata (A. cordata), which belongs to Araliaceae, is a perennial herb widely distributed in East Asia. We evaluated the anti-inflammatory effect of stems (AC-S), roots (AC-R) and leaves (AC-L) extracted with 100% methanol of A. cordata and elucidated the potential signaling pathway in LPS-stimulated RAW264.7 cells. The AC-L showed a strong anti-inflammatory activity through inhibition of NO production. AC-L dose-dependently inhibited NO production by suppressing iNOS, COX-2 and $IL-{\beta}$ expression in LPS-stimulated RAW264.7 cells. AC-L inhibited the degradation and phosphorylation of $I{\kappa}B-{\alpha}$, which donated to the inhibition of p65 nuclear accumulation and $NF-{\kappa}B$ activation. Furthermore, AC-L suppressed the phosphorylation of ERK1/2 and p38. These results suggested that AC-L may utilize anti-inflammatory activity by blocking $NF-{\kappa}B$ and MAPK signaling pathway and indicated that the AC-L can be used as a natural anti-inflammatory drugs.

Hydrocotyle is a genus of prostrate, perennial aquatic or semi-aquatic plants formerly classified in the family Apiaceae, now in the family Araliaceae. Lipoxygenases (LOX) are present in the human body and play an important role in the stimulation of inflammatory reactions. Ethanolic extracts of five Hydrocotyle species (H. ramiflora, H. maritima, H. nepalensis, H. sibthorpioides, and H. yabei) showed inhibition of 23.5~50.6% at 2.0 mg/mL. Their extracts showed LOX inhibition in half maximal effective concentration (EC₅₀) range 15.1~15.7 ㎍/mL. Hyaluronic acid is a glycosaminoglycan, a major component of the extracellular matrix Five extracts of these species inhibited less than 23.0% of Hyaluronidase (HAase) activity at a concentration of 2.0 mg/mL Xanthine oxidase (XO) is a form of xanthine oxidoreductase, a type of enzyme that generates reactive oxygen species. Five Hydrocotyle species were found to have inhibitory activity of XO at 2.0 mg/ml, with 65% having greater than 50% inhibition. H. ramiflora exhibited the highest activity with an inhibition of 80.0%. The results suggested that Lipoxygenases, Hyaluronidase, and Busan 47340, Republic of Korea from five Hydrocotyle species might be multifunctional and prevent the degradation of allergic reactions and inflammation.

A new compound, kalopanaxin F (3), and 11 known compounds (1, 2, 4-12), were isolated from the stem bark of Kalopanax pictus. Their structures were elucidated on the basis of chemical and spectroscopic methods. Five of the compounds (2, 3, 5, 6, and 12) significantly inhibited $TNF{\alpha}$-induced NF-${\kappa}B$ transcriptional activity in HepG2 cells in a dose-dependent manner, with $IC_{50}$ values ranging from 6.2 to 9.1 ${\mu}M$. Furthermore, the transcriptional inhibitory function of these compounds was confirmed based on decreases in COX-2 and iNOS gene expression in HepG2 cells. Compounds 3-7, 9, and 12 significantly activated the transcriptional activity of PPARs dose-dependently, with $EC_{50}$ values ranging from 4.1-$12.7{\mu}M$. Compounds 4 and 5 exhibited $PPAR{\alpha}$, $PPAR{\gamma}$, and $PPAR{\beta}({\delta})$ transactivational activities in a dose-dependent manner, with $EC_{50}$ values of 16.0 and 17.0, 8.7 and 16.5, 26.2 and 26.3 ${\mu}M$, respectively.

Processing of traditional herbal medicine is one of the pharmaceutical technique in oriental medicine. Most frequently used processing method in oriental medicine are roasting and steaming. In this studies, to elucidate the pharmacological transformation of traditional herbal medicine by means of processing them, Ginseng Radix (root of Panax ginseng, Araliaceae) was used as a sample. Processed ginseng radix (SGR, Sun Ginseng) was prepared by steaming of roots of white ginseng (GR) for 3 hours at $120^{\circ}C$. The biological activities of methanol extract of GR and SGR were investigated. According to DPPH radical scavenging effects, and inhibitory effects of xanthine oxidase and AAPH induced hemolysis, PGR exhibited more effective than those of GR in vitro. And, the antifatigue effect of GR and SGR were investigated using a weight-loading forced swimming test by monitoring swimming times and prolonged intensity exercise model rats by measuring blood biochemical parameters. GR and SGR were significantly prolonged swimming times in 8% body weight ratio loaded mice. Also, they had the inhibitory effects on the decrease of blood glucose levels, the elevation of serum creatinine, lactic acid and free fatty acid, and lactic dehydrogenase activities in forces swimming rats with 1% of the body weight attached to the neck for 3 hours. SGR was more excellent than GR on these effect. Also, these effects were transformed to the n-butanol fraction of methanol extract of SGR. From these results, it can be considered that SGR has antifatigue effect.

Panax ginseng C.A. Mayer (Araliaceae, P. ginseng) has been used for the enhancement of vascular and immune functions in Korea and Japan for a long time. Ginsenoside $Rb_1$ and $Rg_3$ isolated from P. ginseng head-part butanolic extract (PGHB) were investigated for anti-inflammatory activity. Ginsenosides and PGHB did not affect the cell viability within $0\;-\;100\;{\mu}g/ml$ concentration to RAW 264.7 murine macrophage cells. Ginsenosides and PGHB inhibited partly lipopolysaccharide (LPS)-induced nitrite production in a dose-dependent manner. The ginsenosides and PGHB showed partially chemical nitric oxide (NO) quenching (maximum 40%) in the cell-free system. Also, ginsenoside $Rb_1$ and $Rg_3$ inhibited markedly approximately 74 and 54% of inducible nitric oxide synthase (iNOS) mRNA transcription from LPS-induced RAW 264.7 cells. Taken together, the inhibitory effect of ginsenosides and PGHB on NO production did not occur as a result of cell viability, but was caused by both the chemical NO quenching and the regulation of iNOS. Additionally, the ginsenoside $Rb_1$ and PGHB inhibited prostaglandin $E_2$ ($PGE_2$) synthesis in a concentration-dependent manner, showed approximately 70-98% inhibition at $100\;{\mu}g/ml$ concentration. And the treatment with ginsenosides and PGHB attenuated partially LPS-upregulated cyclooxygenase-2 (COX-2) gene transcription. Ginsenoside $Rg_3$ suppressed LPS-stimulated interleukin-6 (IL-6) level to the basal in RAW 264.7 cells. From these results, ginsenoside $Rb_1,\;Rg_3$, and PGHB may be useful for the relief and retardation of immunological inflammatory responses and its action may occur through the reduction of inflammatory mediators, including NO, $PGE_2$, and IL-6 production.

$Kalopanax$ $pictus$ is a long-lived deciduous perennial tree in the family Araliaceae mainly distributed in the East Asia. In Korea, this species is of ecological and medical importance. Because typical populations of this species are small and distributed in patches, $K.$ $pictus$ has been considered as a narrow habitat species. To understand the genetic diversity and population structure of this species, the sequence variation of the nuclear ribosomal DNA (nrDNA) internal transcribed spacer (ITS) region was analyzed among 18 different $K.$ $pictus$ populations in the present investigation. The nrDNA ITS sequences of Korean populations investigated in this study showed identical of 616 bp in length, and no any nucleotide variation was found in the entire nrDNA ITS region sequence. This result suggested that the $K.$ $pictus$ populations in Korea might belong to the same isolate, and no mutation was found in the nrDNA ITS region. Compared with other known ITS sequence sources from $K.$ $pictus$ populations, only four variable nucleotide sites were found within the entire ITS region. Very narrow genetic diversity appearing in the population level of $K.$ $pictus$ makes us hypothesize that their relatively isolated habitats. The long-lived traits might be one main reason. However, another probability was that the nr-DNA ITS region might be noneffective in classifying populations of $K.$ $pictus$. Thus, to further understand the phylogenetic relationship of $K.$ $pictus$ populations, more samplings should be performed based on more DNA sequences.
