The objective of this study was to monitor vegetation development process after timber harvesting at (Mt.) Baekwoonsan Seoul National University Forests, Korea. Two monitoring plots were established in 1994 and woody plant were monitored from 1994 to 1999. Vegetation development pattern during last six years(1994-1999) after timber harvesting were as follows; Styrax obassia, Styrax japonica and Lindera erythrocarpa as of the existing tree were competitive species in the first year after clearcut, and Styrax japonica and Lindera erythrocarpa as of sprout tree) and Aralia elata as of seedling were dominant species in the sixth years after clearcut. Species diversity indices of harvested forest interior was decreased at the southwestern slope and increased at the northeastern slope. According to DBH distribution pattern, No. of individuals of Lindera erythrocarpa and Aralia elata showed vigorous growth in the sub-canopy layer and then Styrax japonica, Quercus serrata, Maackia amurensis, Lespedeza maximowixzii, Lindera obtusiloba, Staphylea bumalda, Clero-dendrum trichotomum, Weigela subsessilis, in order showed good growth in the sixth year after clearcut. Lindera erythrocarpa with a reversed J-shaped curve pattern by DBH class will be increased while Aralia elata with a J-shaped curve pattern will be decreased.

This study was conducted to quantify chlorogenic acid content and evaluate biological activity, such as antioxidant, antibacterial, anti-inflammatory, and digestive enzyme activity of Aralia elata ethanol extract (AEE). The SC₅₀ of DPPH and ABTS radical scavenging activities of AEE were 4.79±0.05 mg/mL, 5.79±0.05 mg/mL; total polyphenol and total flavonoid contents were 170.0±1.8 mgGAE/g, 105.5±4.1 mgQE/g, respectively. Nitric oxide (NO) was increased in RAW 264.7 cells and Caco-2 cells with treatment of LPS, and production of NO was inhibited by AEE in a concentration-dependent manner. Production of NO was reduced by 60.0±1.1% in RAW 264.7 cells and 50.7±2.8% in Caco-2 cells at of AEE. Similarly, the production of inflammatory cytokines (TNF-α, IL-1β and IL-6) was inhibited in a concentration dependent manner. Antibacterial activity increased as the dose concentration of AEE increased, and the MIC was 75 mg/mL for L. monocytogenes, and 100 mg/mL for S. typhimurium and H. pylori. In addition, amylase and protease enzyme activity was observed in AEE and increased enzyme activity was observed according to the concentration of the extract. AEE contained 7.06±0.01 mg/g of chlorogenic acid. As a result of the experiment, it is judged that it can be used as basic data for the development of health food using Aralia elata.

Aralia elata Seem. have a typical traditional significance among the wild herbs traditionally. Edible shoots of A. elata will augment consumer's interest due to its high value functional value, eco-friendly and pesticide-free produce. A. elata's root, fruit and bark are used as material of hypoglycemic agent and medicine for diabetes, kidney trouble, acute hepatitis, rheumation arthritis, stomach cancer and gastroenteric trouble. Flavonoid glycoside compound which is separated from A. elata's shoot shows high antioxidative activity. Also, root's identified active materials of antimicrobial was reported to be produced as food preservative and handy antimicrobial. Therefore, this research investigated quantitative morphological characteristics of leaves, spine and bud in naturally dominated and introducted A. elata in south Korea and then considered its principal compound analysis(PCA) and classification analysis(CA) among the 6 improved cultivars and 19 clones. PCA results showed that it show 76% accumulated explanation from four PC. The A. elata clones were classified into five groups; the first group of 15 clones including Yeongok, the second group of 5 clones including Yeoju, the third group of Bonghwa, Ulleung, the fourth group of Yongmunsa, Boseong and the fifth group of Singu. The object of this study will give us invaluable information about breeding by selection of A. elata in south Korea.

We determined the structure of main saponin which extracted from the shoot of Aralia Elata. The results were as follows. 1. The main aglycons and suger of the total saponins of Nr2 sample were identified as oleanolic acid and hederagenin, and glucose, arabinose and rhamnose. A probable new aglycon was isolated and inferred as 1, 3-methylenedioxy-3-dehydroxyoleanolic acid. 2. One compound of Fh saponin (named as Elatoside $Fh_2$) which was obtained first in this species was elucidated as 3-O-$({\alpha}-L-arabinopyranosyl(1{\rightarrow}2)-{\beta}-D-gluco-pyranosyl)$-28-O-${\beta}-D-glucophyranosyl$ oleanolic acid on the basis of chemical and spectral evidence of IR, $^1H$, $^{13}C-NMR$ and MS.

21plants, which collected from Korea and Japan, were applied to antitumor and cytotoxic screening tests against sarcoma 180 a ascitec in mice. The results are summariged as follows : 1) The total packed cell volume method has been used for the antimeoplastic screening for from natural higher plants in Korea. By this method, we have found out that Selaginella involves, Patrinia hispida, Archyranthes japonica and Solanum nigrum having significant activity and also Cydonia sinensis and Rubia akane showed slight activity to antitumor 2) The total packed cell volune method has been used for the antineoplastic screening for from natural higher plants in Japan. Among the 21 tested plants, lsodon japonicus having strong antitumor activity and also Torilis japonica, Aralia elata, Leonurus sibiricus and Rubia cordifolia showed significant activity to anticancer tumor while Forsythia spp and Solanum nigrum showed slight activity to antitumor. 3) Among the 21 tested Korea plants, lsodon excisus and Forsythia Koreana showed strong antitumor activity by the V79 cytotoxic cell screening test.
