This study was carried out to obtain the basic information that can be used to index Acanthopanax in eleven species of China and Korea. The phytochemical components from the berry of Acanthopanax species, were measured by the HPLC analysis. Protocatechuic acid, eleutheroside B, eleutheroside E, scopolin, rutin, hyperoside, chiisanoside, oleanolic acid were found in ethanol extracts from the berry of Acanthopanax species. Total phenolic compound of Acanthopanax sessiliflorum f. chungbuensis berry (0.682%) was about seven times higher than those of Acanthopanax divaricatus f. distigmatis berry (0.091%). As a result, the order of the eleutheroside E content was 1) Acanthopanax sessiliflorum f. chungbuensis (0.554%), 2) A. divaricatus var. albeofructus (0.501%), 3) A. divaricatus f. flavi-flos (0.452%). And also, the order of the chiisanoside content was 1) Acanthopanax senticosus var. subinermis (8.434%), 2) A. seoulense (0.94%), 3) A. divaricatus f. flavi-flos (0.798%).

The antioxidant activities of the root of Panax ginseng and the root bark of Acanthopanax senticosus were compared by in vitro and in vivo experiments. The results of in vitro experiments showed no significant difference between the antioxidant activities of both crude drugs. However, the results of in vivo experiments showed much higher antioxidant activities in Panax ginseng than Acanthopanax senticosus, showing about 80 times greater activity.

Acanthopanax senticosus has been used clinically as tonic. anti-rheumatic and prophylactic purpose for chronic bronchitis. hypertension. ischemic heart disease. and gastric ulcer. We investigated the effects of methanol extracts from Acanthopanax senticosus (KS. KR. MS, MR, HS. HR, SS and SR) on catecholamine and cortisol content of serum after immobilization and on the exercise time to exhaustion in chronic swimming stressed rats. (omitted)

Seven compounds were isolated from the stem of Acanthopanax senticosus by repeated col-umn chromatography. Their structures were elucidated as isovanillin (1), (-)-sesamin (2), iso-fraxidin (3), (＋)-syringaresinol (4), 5-hydroxymethylfurfural (5), eleutheroside B (6), and eleuth-eroside E (7) by spectral analysis. Among them, isovanillin (1) was isolated for the first time from the family Araliaceae.

Antioxidant properties of the extracts of Acanthopanax senticosus were investigated. The dried roots, stems or leaves were extracted with hot water or ethanol each. The ethanol extracts exhibited higher potency than aqueous extracts in scavenging free radicals and in inhibiting microsomal lipid peroxidation: the aqueous extracts of stems showed higher anti-oxidant effects than the root extracts. Copper-mediated LDL oxidation was also protected by the ethanol exlracts: antioxidant effects of the extracts tested were stronger than ascorbic acid, but not butylated hydroxytoluene. The activity of angiotensin converting enzyme was effectively suppressed by the aqueous extracts of the stems. However, in vivo antioxidant properties of the ethanol extracts of the stems did not seem to be significant, judged from the lipid peroxide values of serum and liver in normal mice. Thus, the ethanol extracts of the stems were shown to be more potent for protecting biological systems against various oxidant stresses in vitro, but not in vivo.

Fatty acids, sterols and amino acids were confirmed from seeds of Acanthopanax senticosus for. inermis Harms. Fatty acids were isolated from petroleum ether extract and identified by gas liquid chromatography. Its composition was myristic acid, palmitic acid, stearic acid, oleic acid, linoleic acid, linolenic acid and behenic acid. The composition of sterols that isolated from n-hexane extract were determined by GC/MS. It was confirmed to be a mixture of ${\beta}-sitosterol$ and stigmasterol. And several kinds of amino acids-cysteic acid, threonine, serine, proline, glutamic acid, glycine, alanine, valine, isoleucine, leucine, histidine, lysine and arginine-were confirmed from water fraction.

Five constituents were isolated from the stem of Acanthopanax senticosus. Their structures were elucidated as (-)-sesamin (1), iso-fraxidin (2), 5-hydroxymethylfurfural (3), syringin (4) and acanthoside D (5) by spectral analysis. Among these compounds, 5-hydroxymethylfurfural (3) was isolated for the first time from this plant.

Chiisanogenin (1), hyperin (2) and chiisanoside (3) were isolated from the leaves of Acanthopanax senticosus, and were tested for their inhibitory activities against 6 strains of bacteria. Among them, chiisanogenin (1) revealed broad but moderate antibacterial activities against G(+) and G(-) bacteria, the minimum inhibitory concentration (MIC) being in the range of 50-100 $\mu\textrm{g}$/ml.

High performance liquid chromatography (HPLC) was used for the analysis of chiisanoside in each stem and root of Acanthopanax senticosus collected from South Korea, North Korea, China and Russia. A reverse-phase system using a gradient of H$_{2}$O and acetonitrile as the mobile phase was developed and detection was at 210nm. The analysis was successfully carried out within 30 min. Chiisanoside was measured in the stem and root of A. senticosus collected from various countries.

Epidemiologic studies have shown important relationships between oxidative stress and Alzheimer's disease (AD) brain. In this study, free radical scavenging activity and neuronal cell protection effect of aqueous methanol extracts of Acanthopanax senticosus (A. senticosus) were examined. $H_2O_2$-induced oxidative stress was measured using 2',7'-dichlorofluorescein diacetate (DCF-DA) assay. Pretreatment with the phenolics of A. senticosus prevented oxidative injury against $H_2O_2$ toxicity. Since oxidative stress is known to increase neuronal cell membrane breakdown, leading to cell death, lactic dehydrogenase release, and trypan blue exclusion assays were utilized. We found that phenolics of A. senticosus have neuronal cell protection effects. It suggests that the phenolics of A. senticosus inhibited $H_2O_2$-induced oxidative stress and A. senticosus may be beneficial against the oxidative stress-induced risk in AD.
