Objectives : The cortex and root of Acanthopanax sessiliflorus (AR), a herbal medicine, have been used for several diseases including cancer in Oriental countries. Recently, we reported that AR has an immune-potentiating action. Oga-Power(OP) was made using extract from AR. For these reasons, we hypothesized that OP can potentiate the immune system in terms of accelerating proliferation rates of immune cells such as thymocytes and splenocytes. Methods : In this experiment, proliferation rates of thymocytes and splenocytes were measured using modified 3-[4,5-dimethy -lthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT). No production levels in macrophages isolated from normal mice were measured using Griess method. Results : In our results, treatment with OP accelerated proliferation rates of splenocytes, but did not affect those of thymocytes in vitro. On the other hand, proliferation rates of thymocytes was elevated in vivo. In addition, level of NO production from macrophage separated from abdominal cavity of normal mice was elevated by treatment with OP. Conclusions : In conclusion, OP has immune-potentiating action, by acceleration of splenocyte proliferation and elevation of NO production level from macrophages.

Acanthopanax sessiliflorus SEEM extracts(AS) have been used to treat patient with diseases including cancer in Oriental countries. Recently, AS was known to have anti-cancer and immuno-stimulating activites. For these reasons, we investigated the effects of AS following gamma-ray irradiation on cytotoxicity for solid tumor cell line (S-180) and immune-potentiating ability such as proliferation of thymocytes and splenocytes. Finally we also investigated tumor weight and survival rate in tumor bearing mice. In our results, Treatment with AS suppressed proliferation of solid tumor cells (S-180) effectively. Treatment with AS accelerated thymocyte and splenocyte proliferation in tumor bearing mice. In addition, Treatment with AS reduced tumor weight and prolonged life of tumor bearing mice. In conclusion, we demonstrate that AS following gamma-ray irradiation is useful to treat patients with cancer, and also demonstrate that AS have both direct cytotoxic ability for cancer cells and indirect immune-stimulating action for thymocytes and splenocytes.

오갈피속 수종은 우리나라에 10여 종 있는 것으로 보고되고 있는데(김영진, 등 1997)약용성분이 가장 뛰어난 수종은 가시오갈피(Acanthopanax senticosus (Ruper. et Max.)Harms)로 알려져 있다. 가시오갈피는 높이 2∼3 m의 낙엽활엽관목으로서 강한 햇볕이 드는 더운곳에서는 거의 발견되지 않으며 내음 및 내한성이 강하다.(중략)

"Ga Si O Gal Pi" is one of the Korean crude drugs used mainly to cure arthritis, acute gastritis, and beriberi. With regard to the botanical origin of "Ga Si O Gal Pi", it has been considered to be Acanthopanax species of Araliaceae, but there was no pharmacognostical confirmation on it. To clarify the botanical origin of "Ga Si O Gal Pi", the anatomical characteristics of the branch of Acanthopanax species growing wild in Korea and Japan, A. chiisanensis, A. divaricatus, A. koreanum, A. rufinerve, A. senticosus, A. seoulense, A. sessiliflorus, A. sieboldiaum were studied. As a result, it was clarified that "Ga Si O Gal Pi" was the branch and rarely the bark of branch of Acanthopanax senticosus.

'O Ga Pi Ip' has been used in Korea to cure rheumatism, neuralgia, edema, dematopathy, and impotence. The botanical origin of the crude drug has not been confirmed pharmacognostically. To clarify the botanical origin of 'O Ga Pi Ip', the morphological and anatomical characteristics of the leaves of Acanthopanax species growing in Korea and Japan, A. chi-isanensis Nakai, A. Koreanum Nakai, A. rufinerve Nakai, A. senticosus (Rupr.et Maxim). Harms, A senticosus (Rupr.et Maxim.) for inermis Harms, A. seoulense Nakai, A sessiliflorus (Rupr. et Maxim.) Seem, A. divaricatus Seem, A. sieboldianum Makino were compared. As a result, it was determined that 'O Ga Pi Ip' was the leaf of A. sessiliflorus (Rupr. et Maxim.) Seem, A chiisanensis Nakai, and A. koreanum $Nakai_I$.

Analysis of flavonoid contents in the fruits of Acanthopanax species (A. chiisanensis, A. divaricatus, A. koreanum, A. senticosus, and A. sessiliflorus) was conducted by high performance liquid chromatography. A Discovery$^{(R)}$ C18 ($4.6{\times}250$ mm, 5 ${\mu}m$) column was used with a gradient mobile phase of water and acetonitrile (90 : 10 to 60 : 40 for 60 min) and UV detection was conducted at 350 nm. The contents of rutin, hyperin, quercetin, afzelin, and kaempferol were 0.063~0.540, 0.494~7.480, 0.584~0.704, 0.388~0.567, 0.190~0.471 mg/g, respectively, in the fruits of Acanthopanax species. Total content of flavonoids in the fruits of Acanthopanax species was highest in those of A. chiisanensis. Furthermore, hyperin was the most abundant compound in the fruits of Acanthopanax species. Consequently, our results demonstrate that the fruits of Acanthopanax species containing flavonoids have promising potential as a new income source of agriculture and industry in medicinal natural products, health supplements, and beverages.

This work was carried out to investigate the antioxidative effects of Acanthopnax sessiliflorus from Jeongseon County for the purpose of development of a novel antioxidant from natural products. The antioxidant activity was determined by using electron paramagnetic resonance (EPR), not measuring the radical scavenging effect on 1,1-diphenyl-2-picrylhydrazyl (DPPH) which have bun used for antioxidant activity of natural sources. Although DPPH radical scavenging activity assay have been generally used for antioxidant activity, this assay is nut appropriated for determinating which radical is scavenged by extracts from natural products. Using EPR, we determinated whether A. sessiliflorus extracts from Jeongseon County scavenge specific radicals or not. On experiment of scavenging superoxide anion radical, hydroxyl radical, nitrogen dioxide and peroxinitrite. Extracts from A. sessiliflorus showed high antioxidant activities to reactive oxygen and nitrogen species. These result suggest that extracts from A. sessiliflorus act as an antioxidant by scavenging reactive oxygen and nitrogen species and used as new cosmetic ingredients for anti-oxidative stress in skin.

This study was carried out in order to investigate the functional properties of 50% methanol extracts from four parts (root, stem, leaf and fruit) of Acanthopanax sessiliflorus by means of measuring the contents of eleutheroside B, E, and total polyphenols as well as determining electron donating ability (EDA), nitrite scavenging ability (NSA), and anticancer activity. The highest contents of eleutheroside B and E were found in the fruit (538.99 ${\mu}g/g$) and the stem (556.00 ${\mu}g/g$). The root extract demonstrated the highest polyphenol content (2.97 mg/g). EDA of the stem and root extracts were 90.21% and 85.71%. All of the extracts showed 81.5-93.0% of NSA at pH 1.2. In addition all extracts indicated no cytotoxicity to normal cell line (DC2.4). The root extract had a 23% inhibitory effect against the stomach cancer cell line (SNU-719). These results revealed that 50% methanol extracts from A. sessiliflorus can be used as a potential resource of nutraceuticals.

Rooting test of 5 species plants in Acanthopanax genus was carried out to see the comparative effect of growth regulators NAA IBA and IAA. And the results are summarized as in the following compendia; (1) When hard and soft-wood cutting from new shoot of 5 species were taken and dipping treated with growth regulators such as NAA IBA and IAA at varied concentration levels their roofings were mostly more superior to the control that untreated. And also treatment of NAA and IBA among treated substances were more effective than IAA. (2) The effects on the rooting number and rate made a great difference according to species of Acanthopanax genus even if the same regulator was treated. (3) Decreasing effects of rooting by high concentration obstacle (especially at 2,000 rpm) of NAA and IBA in other species except A. sieboldianum were mostly serious. On the other hand, that in case of IAA treatment was not risen in most species except A. sessiliflorus.

High performance liquid chromatography (HPLC) was used for the analysis of chiisanoside in Acanthopanax species. A reverse-phase system using a gradient of H$_2$O and acetonitrile as the mobile phase was developed and a wavelength of detection was at 210 nm. The analysis was successfully carried out for 30 min. Chiisanoside was measured in the fruit, stem and root of A. sessiliflorus, A. koreanus, A. divaricatus and A. senticosus.
