Most Araliaceae plant species distributed in Korea are economically important because of their high medicinal values. This study was conducted to develop barcode markers from sequence analysis of chloroplast DNA in 14 taxa of Araliaceae species grown in South Korea. Sequencing of seven chloroplast DNA regions was performed to establish the DNA barcode markers, as suggested by the Consortium for the Barcode of Life (CBOL). From the sequence analysis of chloroplast DNA, we identified specific sequences and nucleotides that allowed us to discriminate among each other 14 Korean Araliaceae species. The sequence in the region of psbA-trnH revealed the most frequent DNA indels and substitutions of all 7 regions studied. This psbA-trnH marker alone can discriminate among all 14 species. There are no differences between Korean and Chinese Panax ginseng in all seven sequenced chloroplast DNA regions. A phylogenetic tree constructed using the seven chloroplast DNA regions revealed that Tetrapanax papyriferus should be classified as an independent clade. The Aralia and Panax genera showed a close phylogenetic relationship. Five species in the Eleutherococcus genus were more closely related to Kalopanax septemlobus than to any Panax species.

The effects of temperature stress and paraquat on the superoxide dismutase (SOD) activity and the photochemical efficiency of photosystem II were studied in the leaves of Araliaceae plants. The SOD activity of Acanthopanax koreanum leaf discs increased at 4$^{\circ}C$ and 28$^{\circ}C$, and increased significantly at 4$^{\circ}C$ ,28$^{\circ}C$ and 35$^{\circ}C$ in the presence of paraquat. However, the SOD activity of Dendropanax morbifera leaf discs decreased at 4$^{\circ}C$, 28$^{\circ}C$ and 35$^{\circ}C$ regardless of paraquat treatment. The photochemical efficiency of photosystem II, Fv/Fm, of leaf discs of A. koreanum and D. morbifera fell remarkably at 35$^{\circ}C$. In the presence of paraquat, the Ev/Fm values fell slightly at 4$^{\circ}C$ in A. koreanum leaf discs and at 35$^{\circ}C$, in D. morbifera leaf discs. These results indicate that A. koreanum plants are more resistant to temperature stress or oxidative stress than D. morbifera plants although their photochemical efficiency falls slightly at 4$^{\circ}C$ in the presence of paraquat.

This study was conducted to investigate the effects of Araliaceae water extracts on lipid concentrations in streptozotocin(STZ)-induced diabetic rats. The Male Wistar rats were divided into normal and diabetic group. The diabetic group was futher subdivided into the control group(DM) and the Araliaceae water extracts supplemented group: Aralia elata(AE), Acanthopanacis cortex(AC) and Ulmus davidiana(UD). The extracts were supplemented with 1.14% of raw Araliaceae/kg diet for 7 weeks. Diabetes was induced by injecting STZ(55 mg/kg B.W., i.p.) once 2 weeks before sacrifying. The net weight gain and feed efficiency ratio were significantly lower in the STZ-induced diabetic group than in the normal group. However, all of the Araliaceae water extracts supplemented groups resulted in an increase of body weight compared to the DM group. The triglyceride, total cholesterol and free cholesterol concentrations in plasma and liver were significantly higher in the DM group than in the normal group. However, the supplementation of Araliaceae water extracts increased plasma HDL cholesterol concentration, while decreased plasma VLDL, LDL-cholesterol concentra-tions in Araliaceae water extracts supplemented group.

In the present field study, the number of woody flora of Mt. Songni were summarized as 44 families, 89 generas, 140 species, 10 varities and 2 forms. Also, the flora among inland areas such as Mt. Paektu, Mt. Sorak, Mt. Songni, and Mt. Chiri, and insular areas, such as Oyoujong Island. Tokjok Archipelago, Kok-unsan Archipelago and Cheju Island, were compared, respectively, in order to interpret the characteristics of distribution patterns of the flora of this area. The flora of Mt. Songni were characterized as similar to the flora of Mt. Sorak, and also with that of Mt. Chiri. It was interpreted both the northern types of plants such as Aceraceae, Araliaceae, Fagaceae, Tiliaceae and Ulmaceae and the southern types of plants such as Celastraceae, Convolvulaceae, Euphorbiaceae, Rhamnaceae, Solanaceae, Crassulaceae and Urticaceae were fluxed considerably into this region.

The purpose of this study is to describe and compare the morphological characteristics of seeds of 12 taxa of Araliaceae, and to evaluate their possible use for taxonomic considerations. For light microscope observations and measurements, the seeds were observed using Image Analyzing System. The observations were made on twenty randomly selected seeds of each species. Obtained data were statistically processed using analysis of variance. Principal Components Analysis indicated four groups of characters, the genera Aralia, Eleutherococcus, Panax and the others, which explained 65.47% of the total variation. As a results of Cluster Analysis using the eleven variables, 12 species of Araliaceae were also discriminated into four groups. Eleutherococcus senticosus and E. gracilistylus were closely related, which is well supported by the results from recent molecular studies. Also, the genera Dendropanax and Eleutherococcus were closely related in terms of seed characters.

This study was conducted to investigate the effects of Aralia elata, Acanthopanacis cortex and Ulmus davidiana water extracts on plasma glucose and biomarkers in the streptozotocin (STZ)-induced diabetic rats. Male Wistar rats were divided into normal and diabetic groups. The diabetic groups subdivided into the control group (DM), Aralia elata (DM-AE), Acanthopanacis cortex (DM-AC) and Ulmus davidiana (DM-UD). The extracts were supplemented in diet base on 11.42 g of raw materials/㎏ diet for 7 weeks. The diabetes was induced by injecting STZ (55 ㎎/㎏ B.W., i.p.) once 2 weeks before sacrifying. Plasma glucose level was significantly higher in the DM group than in the normal group, whereas insulin and C-peptide concentrations were significantly lowered in the DM groups compared to the normal group. These parameters were normalized in the DM-AE, DM-AC and DM-UD supplemented groups. Plasma albumin content was significantly lowered in the DM group compared to the normal group, yet it was significantly higher in the DM-AE group than in the DM group. Bilirubin and creatinine contents were elevated in the DM group, while the supplementation of Aralia elata, Acanthopanacis cortex and Ulmus davidiana water extracts ameliorate the change of these contents in STZ-induced diabetic rats. Plasma AST, ALT, ALP and LDH activities were significantly higher in the DM group than in the normal groups. The supplementation of Araliaceae family water extracts significantly lowered these parameters compared to the DM group. Accordingly, these results indicate that Aralia elata, Acanthopanacis cortex and Ulmus davidiana water extracts would seem to improve the glucose and biomarker in STZ-induced diabetic rats.

Phylogenetic relationships among species in Araliaceae were analyzed using PCR-RAPD and sequence of ITS region of nuclear ribosomal DNA based on samples collected in Korea. RAPD analysis showed various polymorphic bands which were able to differentiate species and genus, and specific bands showing variations among individuals within species. Cluster analysis using gel images revealed high molecular variability within species of Aralia eleta. No significant variation was found among cultivated species of Panax ginseng, but they showed high genetic differences with wild type of the species. In ITS analysis, specific sequences for each genus and species were observed and these were allowed to differentiate species and genus. Phylogenetic analysis using ITS sequences showed that Acanthopanax and Kalopanax had a close relationship, and Aralia and Panax are monophyletic, but genus Hedera is different species from other species in family Araliaceae in this study. The results showing close relationship between genera Aralia and Panax were also observed in RAPD analysis. Contrary to the results of RAPD analysis of Panax ginseng, sequence analysis of ITS showed no significant difference between wild mountain ginseng and cultivated species of P. ginseng. Also, both RAPD and ITS analysis of P. ginseng showed no significant genetic variability among cultivation sites. Results indicate that P. ginseng cultivating in Korea is monophyletic. The molecular analysis used in this study agreed on classification using morphological feature. These results suggest that molecular techniques used in this study could be useful for phylogenetic analysis of Araliaceae.

The study was performed using of ethanol and water extracts of Fatsia japonica Decne. et Planch. in anticancer and immune activities. All extracts of 1.0 $g/{\ell}$ concentration were increased in over 60% of the anticancer activites in A549 and MCF7 cells. Root barks inhibited 55%, 74% in A549 and MCF7 cell by adding ethanol extracts of $g/{\ell}$ concentration. The cytotoxicity of human lung nomal cell (HEL299) counted up to about 22% for ethanol extracts of root barks in 1 $g/{\ell}$ concentration. The activity of human immune T and B cells were increased up to $140{\sim}170%$ by adding ethanol extract of the root barks. Increasing trend of secretion of cytokine (IL-6, $TNF-{\alpha}$) from human B and T cell for 5 days cultivation has been abserved. From the results, the anticancer and immune-stimulatory activities of the roots extract were higher than the extracts of other parts.

The experiment was carried out to determine the optimum fertilization level showing high quality on Aralia cordata Thunb. Plant height of fertilization(27-15-27kg) was promoted significantly compared with conventional fertilization(17-9-17kg). This effect was followed with increment of blanched length. Among underground parts, main root length was increased in conventional fertilization, and more cultural year was prolonged, the more yield of dry root weight was increased. Fresh leaf yield to produce high quality of Aralia cordata plant was remarkably increased about 6% in fertilization of 27-15-27kg per 10a. As a result, to produce higher good quality of the plant. the optimum fertilization level was 27-15-27kg per 10a.
