'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 $Nakai_I$.

The content of hyperin in Acanthopanax species was determined by high performance liquid chromatography (HPLC). Hyperin was quantified by a reverse-phase column with elution program [initially gradient solvent (acetonitrile : water = 85 : 15 to 80 : 20 for 20 min), then isocratic solvent (acetonitrile : water = 80 : 20 for 20 min), and finally gradient solvent (acetonitrile : water = 80 : 20 to 65 : 35 for 20 min)]. UV detection was conducted at 210 nm. The content of hyperin in the fruits of Acanthopanax was measured in the species A. chiisanensis (2.04 mg/g), A. sessiliflorus (1.13 mg/g), A. divaricatus (0.98 mg/g), A. koreanum (0.75 mg/g) and A. senticosus (0.05 mg/g). The content of hyperin in A. chiisanensis was higher than that of other Acanthopanax species.

The chemical composition of the volatile constituents from the leaves and stems of endemic Acanthopanax koreanum and A. chiisanensis collected from Mt. Deokyu was determined by GC and GC/MS spectrometric analysis with the aid of NBS, Wiley Library and RI indice searches. The major constituents identified were ${\delta}-3-carene$ (31.34%), l-limonene (17.01 %), ${\beta}-elemene$(4.53%), trans-p-menth-2-ene-1,8-diol(3.13%), 1,8-cineole (4.73%), 1-dodecen-3-yne (2.64%) and (Z)-3,7-dimethyl-1,3,6-octatriene (3.21%) in A. koreanum, and ${\delta}-3-carene$ (14.78%), limonene (7.24%), t-ocimene (7.22%), ${\alpha}-terpinolene$ (8.76%), ${\gamma}-elemene$ (4.32%), ${\beta}-selinene$ (7.72%), veridifloral (3.25%) and dodecane (2.44%) in A. chiisanensis.

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.

High performance liquid chromatography (HPLC) was used for the analysis of the lignans eleutheroside B and eleutheroside E in the fruits of Acanthopanax species. A reverse-phase system using a gradient of $H_2O$ and acetonitrile as the mobile phase was developed and detection was at 210 nm. The analysis was successfully carried out within 20 min. The content of eleutheroside B and eleutheroside E in Acanthopanax species was measured in the fruits of A. senticosus (0.58 and $1.66\;{\mu}g/mg$, respectively), A. sessiliflorus (1.15 and $8.49\;{\mu}g/mg$, respectively), A. koreanum (2.16 and $1.80\;{\mu}g/mg$, respectively), and A. divaricatus (1.06 and $7.08\;{\mu}g/mg$, respectively).

The aim of this study was to investigate the method validation for the determination of eleutherosides (B and E) and ${\beta}$-glucan in Acanthopanax (A.) koreanum. This medicinal plant reportedly mainly included eleutherosides which exhibit the pharmacological effects, and ${\beta}$-glucan substantially enhances the function of the immune system by activating macrophages. The specificity, linearity, precision, accuracy, limit of detection (LOD, S/N=3), and limit of quantification (LOQ, S/N=10) were measured by HPLC and enzymatic methods. Our results showed that the coefficient of calibration correlation ($R^2$) for eleutheroside B and E were 0.9997 and 0.9999, respectively. The limits of detection (LOD) for eleutheroside B and E were $0.050{\mu}g/mL$ and $0.025{\mu}g/mL$, respectively. The recovery rate of eleutheroside B and E were revealed in the high range of 100.66~110.04% and 94.26~111.62%, respectively. The inter-day precision of eleutheroside B and E in the root and stem in A. koreanum were 1.4~5.0% and 1.1~2.5%, respectively. The intra-day precision of eleutheroside B and E in the root and stem in A. koreanum were 2.8~2.9% and 0.4~1.1%, respectively. Furthermore, the inter-day and intra-day precision of ${\beta}$-glucan in the stem, leaf, and fruit of A. koreanum were 1.32~5.67% and 8.01~11.76%, respectively. In conclusion, the methods were validated for the detection of eleutherosides and ${\beta}$-glucan in A. koreanum.

From the water fraction of the MeOH extract, three compounds, 1,3,4,5-terrahydroxycyclo-hexanecarboxylic acid 3-(3,4-dihydroxycinnamate) (chlorogenic acid), $quercetin 3-O-{\beta}-D-galactopyranoside(hyperoside)$, and 1 (R)-hydroxy-3,4-seco-lup-4(23), 20(30)-dien-3,$11{\alpha}-olactone-{\alpha}-L-rhamnopyrnaosy(1{\rightarrow}4)-{\beta}-D-glucopyanosy(1{\rightarrow}6)-{\beta}-L-glucopyrnaosyl$ ester (chiisanoside) were isolated and their strutures determinated by $^1H-NMR,{\;}^{13}C-NMR$, IR, and FAB-Mass. Chlorogenic acid and Chiisanoside had been quantitated by HPLC from eight Acanthopanax species per 10 g A. koreanum 19.82, 4.17 mg, A. nambunensis 65.00, 1.86mg, A. chiisanense 27.19, 8.17mg, A. sessiliflorum 7.49, 5.88 mg.
