This study was carried out to obtain the basic informations for phenolic compounds by various sections of Acanthopanacis Caulis. The phenolic compounds of Korean Acanthopanacis bark and lignum (Acanthopanax divaricatus var. albeofructus, Acanthopanax koreanum) were measured by the HPLC analysis. The content of total phenolic components of Acanthopanax koreanum bark (1.532%) was about 9.9 times higher than that of Acanthopanax koreanum lignum (0.155%). And also, The content of total phenolic components of Acanthopanax divaricatus var. albeofructus bark (0.420%) was about 2.8 times higher than that of Acanthopanax divaricatus var. albeofructus lignum (0.149%). Eleutheroside E, a functional ingredient of Acanthopanacis Caulis, showed 3.6 times higher contents of Acanthopanax koreanum bark (0.144%) than Acanthopanax koreanum lignum (0.040%). In the case of Acanthopanax divaricatus var. albeofructus bark (0.129%), the content of the eleutheroside E was 1.7 times higher than that of the Acanthopanax divaricatus var. albeofructus lignum (0.074%).

Acanthopanax divaricatus var. albeofructus is one of the indigenous medicinal plant and the fruits of Acanthopanax spp. used as a remedial for "wipe out evil wind". Two anthocyanin were isolated from the fruits of Acanthopanax divaricatus var. albeofructus. Their structures were elucidated as cyanidin 3-lathyroside (1) and cyanidin 3-galactoside (2) by chemicophysical and spectroscopic analysis. And also, four chemical, syringin, chlorogenic acid, caffeic acid and acanthoside D were identified. Both anthocyanide were isolated for the first time from Acanthopanax species. cyanidin 3-lathyroside is one of the rare anthocyanin in natural resources.

Acanthopanax species (Araliaceae) traditionally has been used as analgesics, stimulant of immune system, and replenishment of body functions. Acanthopanax divaricatus var. albeofructus is indigenous plant to Korea. The antioxidant activities of compounds from A divaricatus var. albeofructus were determined by 1,1-diphenyl-2-picrylhydrazyl (DPPH) method and thiobarbituric acid reactive substance (TBARS) assay on human plasma low-density lipoprotein (LDL). The triterpenoid and lignan constituents from this plant showed antioxidant activities and the lignan, l-sesamin exhibited the most potent antioxidant activity in Cu$^{2+}$ -induced LDL oxidation.n.

In the present study, water extracts of Acanthopanax divaricatus var, albeofructus and Eleutherococcus divaricatus var. chiisanensis were prepared and their antioxidant and anti-inflammatory effects were compared. The water extract of Acanthopanax divaricatus var, albeofructus showed significantly higher activity in total polyphenol and flavonoid contents, while there were no significant differences in ABTS/DPPH radical scavenging activities and ferric reducing antioxidant power. However, the water extract of Eleutherococcus divaricatus var. chiisanensis at the highest dose showed significantly lower capacity in nitric oxide production than that of Acanthopanax divaricatus var, albeofructus. Taken together, there were differences between Acanthopanax divaricatus var, albeofructus and Eleutherococcus divaricatus var. chiisanensis in total polyphenol/flavonoid contents and anti-inflammatory effect, however, the antioxidant effect was almost similar.

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 cultivation methods of Acanthopanax in Korea need to be optimized. Hence, this study investigated the effect of different fertilizer ratios and planting dates on the growth and acanthoside D content of two (2) Acanthopanax species. The current recommended fertilizer rate of 10.5-8.5-8.5 $kg/ha^-$ ($N-P_2O_5-K_2O$, respectively) produced the best plant growth of Acanthopanax. For the first year, the acanthoside D content resulting from the 2P (2x phosphate) rate was higher than that from the other fertilizer ratios, yet there were no significant differences resulting from the various treatments for either Acanthopanax divaricatus or Acanthopanax koreanum. Similarly, for the second year, there were no significant differences in the acanthoside D content resulting from the various fertilizer ratios, although for both species the acanthoside D content resulting from the 2P rate was slightly higher than that from the other treatments. Therefore, the results indicated that doubling the amount of phosphate increased the acanthoside D content. Plus, the optimum planting date with respect to growth and productivity for Acanthopanax divaricatus was identified as April 15.

Acanthopanax species (Araliaceae) has been traditionally used as analgesics, stimulants of immune system, and replenishment of body functions. Acanthopanax divaricatus var. albeofructus is a indigenous plant in Korea. The anti-lipid peroxidation activities of the loaves and root bark extracts of A divaricatus var. albeofructus were determined. Activities of MeOH extracts were examined in vitro and in vivo with control group intoxicated by carbon tetrachloride. Both extracts showed significant inhibitory effects on the lipid peroxidation.

Four 3,4-seco-lupane trierpenoids were isolated from the MeOH extract of the leaves of Acanthopanax divaricatus forma flavi-flos Yook by using various column chromatography. The chemical structures of isolates were identified as chiisanogenin, chiisanoside, isochiisanoside and 11-deoxyisochiisanoside on the basis of physico-chemical and spectroscopic date($^1H-NMR,\;^{13}C-NMR$M$, 2D-NMR and FAB-MS). These compounds were isolated for the first time from A. divaricatus forma flavi-flos.

Acanthopanax divaricatus, a member of the Araliaceae family, has been used as an invigorant in traditional Korean medicine. During disease monitoring, a stem with small, irregular, brown lesions was sampled at a farm in Cheonan in 2011. The symptoms seen were sunken cankers and reddish-brown needles on the infected twig. The isolated fungal colonies were whitish, having crenated edges and aerial mycelium on the surface, and with black gregarious fruiting bodies. The reverse plate was creamy white. Conidia were $17{\sim}22{\times}3.5{\sim}4.2{\mu}m$, fusiform, 4-septate, and straight to slightly curved. The nucleotide sequence of the partial translation elongation factor 1 alpha gene of the fungal isolate, shares 99% sequence identity with that of known Pestalotiopsis ellipsospora. Based on the results of the morphological and molecular analyses, the fungal isolate was identified as P. ellipsospora. In Korea, this is the first report of canker on A. divaricatus.

This study was conducted to identify the effect of shading and pinching on growth and acanthoside-D content of Acanthopanax divaricatus var. albeofructus and A. koreanum Nakai. Different pinching heights showed no significant differences in terms of plant growth and acanthoside-D content but higher values showed that pinching A. divaricatus at 60 cm and A. koreanum at 30 cm favored good growth and higher fresh weight in the shoots. The content of acanthoside-D was not significantly affected by pinching heights. Also, no significant difference in acanthoside-D content was found between the lower and upper part of plant in the first year. However it was much higher in the lower part than the upper part in the second year, which indicated that the content of acanthoside-D was comparatively high in the lower part where lignification is much advanced. Shading showed benefits in terms of growth of A. divaricatus while only 50%-shading was favorable for A. koreanum to achieve superior growth. Overall, results indicated that shading had favorably affected the growth of the 2 Acanthopanax species while no-shading is better if we opt to achieve higher acathoside D content.
