Objectives : The present study compared Aralia continentalis Root and Angelica pubescens Root used in Korea and China respectively concerning their anti-oxidant effect Methods : We tested the anti-oxidant effect through in vitro experiment and in vivo experiment that induced oxidative stress using ethanol. Results : 1. DPPH scavenging activity was stronger in Aralia continentalis Root than in Angelica pubescens Root 2. Superoxide anion radical scavenging activity was similar between Aralia continentalis Root and Angelica pubescens Root 3. The linoleic acid peroxidation inhibition effect was stronger in Aralia continentalis Root than in Angelica pubescens Root. 4. The phenolic component was higher in Aralia continentalis Root than in Angelica pubescens Root. 5. Both Aralia continentalis Root and Angelica pubescens Root increased the concentration of GSH and decreased SOD activity in mice, in which oxidative stress was induced, and the effect was stronger in Aralia continentalis Root. 6. Aralia continentalis Root increased GSH peroxidase activity but Angelica pubescens Root did not have such an effect. 7. Neither Aralia continentalis Root nor Angelica pubescens Root had a significant effect on catalase, ADH and ALDH in mice, in which oxidative stress was induced. Conclusions : Aralia continentalis Root has a stronger anti-oxidant effect than Angelica pubescens Root. Thus, although Aralia continentalis Root is not an original plant recorded in botanical literature, it may be usable based on the data about its effects.

Aralia continentalis Kitagawa (Araliaceae), known as "Dokwhal" in Korea, has been widely used in traditional Korean medicine for analgesia, neuralgia, sweating, and rheumatism. The biological activity was estimated with methanol extracts of from cultivated roots and adventitious roots of A. continentalis. DPPH and ABTS activities showed the highest activity in methanol extract of adventitious roots at 175.6 and $279.7{\mu}g/mL$ ($RC_{50}$), respectively. Antioxidant activity of methanol extract of the adventitious roots was higher than other samples. In the antibacterial activity assay (paper disc method), the methanol extract of adventitious roots showed activity against S. aureus, S. epidermidis, B. subtilis, and S. enterica. This study demonstrated that adventitious roots of A. continentalis, which was produced for the first time in the roots of A. continentalis, can be used as a natural antioxidant and antibacterial agents.

Seven triterpenoid saponins such as oleanolic acid 28-O-{\beta}-D-glucopyranosyl$ ester, hederagenin $28-O-{\beta}-D-glucopyranosyl$ ester, chikusetsusaponin IVa, udosaponin A, salsoloside C, udosaponins F and C were isolated from the aerial parts of Aralia continentalis, among which two $28-O-{\beta}-D-glucopyranosyl$ esters of oleanolic acid and hederagenin are isolated for the first tome from this plant. These results suggested that the chemical components of Korean Dokwhal are practically identical to those of japanese Udo supporting the chemotaxonomical point of view.

Six flavonoids were isolated from the leaves of Aralia continentalis. Their structures were characterized as kaempferol, quercetin, 6'-O-acetyl astragalin, astragalin, trifolin and hyperoside by chemical and spectroscopic evidences. This is the first isolation from this plant.

'Angelicae Pubescentis Radix' (APR) is an important oriental medical preparation. In Korea, Aralia continentalis has been recognized as the source plant of APR. Aralia cordata, which is difficult to distinguish from A. continentalis, and Heracleum moellendorffii, which is frequently used in lieu of A. continentalis, are traded in Korean herbal markets. In contrast, in China, Angelica pubescens is recognized as the source plant of APR. In this study, we devised a method not only to discriminate A. contientalis from A. cordata, but also to discriminate both A. contientalis and A. cordata from H. moellendorffii and A. pubescens. Based on the discrepancy in the sequences of specific regions of ITS, we designed a Cont F/ Cont R primer set to amplify a 173 bp PCR band that appears only in A. continentalis. Additionally, we designed an Ara F/ Ara R primer set to amplify a 278 bp PCR band that appears in both A. continentalis and A. cordata. Using these primer sets and the ST R primer to confirm the PCR amplification results, we developed a simple multiplex PCR method for differentiating A. continentalis from A. cordata and to concurrently differentiate both A. continentalis and A. cordata from other APR herbs.

Protoplasts of Panax ginseng C. A. Meyer and Aralia continentalis K. (Araliaceae) were isolated from callus cells and mesophyll cells, respectively. The maximum yield of protoplasts isolated from callus cells of P. ginseng were obtained by incubation for 3 hrs in the enzyme mixture of 0.5% macerozyme, 1.5% cellulase, and 0.5 M mannitol as an osmoticum. In the case of mesophyll cells of A. continentalis, the highest yield of protoplasts were obtained by incubation for 5 hrs in the enzyme mixture of 1% macerozyme, 2% cellulase, and 0.6 M mannitol. A polyethylene glycol (PEG) treatment induced an intergeneric fusion of the protoplasts. The fusion products, that is, heterokaryocytes were obtained by treatment of 50% PEG containing 0.05 M Ca salts.

Two phenolic acids were isolated from the hydrolyzed butanol fraction of Aralia continenetalis K. in crystalline form. They were identified by chemical tests and by analysis of spectra of UV, IR and NMR as ferulic acid and caffeic acid.

Dried parts of the herb medicines are difficult to distinguish morphologically. Heracleum moellendorffii cordata has often been sold instead of Aralia cordata in herbal medicine markets. Therefore, this study was conducted to develop the key for discrimination between them using the RAPD analysis and morphological characteristics. Thirty decarmer oligonucleotide primers were screened for the RAPD analysis, and four primers generated distinct RAPD markers specific to Aralia cordata, Angelica pubescens maxim f. biserrata, and Heracleum moellendorffii. The specific RAPD patterns generated by the selected primers were reproducible from dried materials. In comparison of morphological characteristics, Aralia cordata seems to be entirely developed in xylem fiber, but not developed in pith.

Endophytic fungi were isolated from surface sterilized root tissues of Aralia elata and Aralia continentalis, collected from farmer's field in Chungnam province, Republic of Korea, in 2005. Based on ITS sequence analysis, 24 fungal genera were characterized from 359 isolates, belonging to 22 Ascomycota, 1 Glomeromycota and 1 Oomycota. Strumella, Rhizopycnis and Entrophospora in A. elata and Rhizopycnis and Leptosphaeria in A. continentalis were the most abundant taxa. Out of 24 genera, Entrophospora, Leptodontidium, Neoplaconema, Paraconiothyrium, Rhizopycnis, Strumella and Tumularia were new to Korea. A total of 110 isolates were tested for antifungal activities against six plant pathogenic fungi. Out of these, 39 isolates showed antifungal activity against at least one plant pathogenic fungi. Four isolates of Pyrenochaeta, 1 isolate of Entrophospora and 1 unidentified fungus strongly inhibited the growth of six plant pathogenic fungi.
