Acanthopanax species are well known medicinal plants in Korea for their adaptogenic efficacy. Regarding to the botanical classification of Acanthopanax koreanum, an indigenous species in Jeju island of Korea, it has been classified as different species of Acanthopanax genus. However, the morphological characteristics of A. koreanum are very similar with other Acanthopanax species, especially with A. gracilistylus. In order to provide further classification information among these botanically related species, microscopic and morphological studies on these Acanthopanax species were performed. In this result, it has been found that A. koreanum is similar to A. gracilistylus in terms of anatomical observation and was distinguished from A. sieboldianus by their morphological and anatomical differences.

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%).

Acanthopanax species (Araliaceae) has been traditionally used as tonic, analgesic, stimulant of immune system, and replenishment of body function. The antioxidant activities of leaf and root bark of Acanthopanax species were determined by 1,1-diphenyl-2-picrylhydrazyl (DPPH) method and thiobarbituric acid reactive substances (TBARS) assay and relative electrophoretic mobility (REM) on human plasma low density lipoproteins (LDL). Acanthopanax divaricatus var. albeofructus and Acanthopanax for. nambunensis showed potent antioxidant activities.

The chemistry of secondary products from Acanthopanax species and their pharmacological activities were reviewed. A nitrogenous compound, a furan compound, a quinoid, benzoids, coumarins, phenylpropanoids, lignans, flavonoids, terpenoids, phytosterols, polyacetylenes, a pyrimidine, cyclitols, monosaccharides and an aliphatic alcohol have been isolated from Acanthopanax species and have been shown to have various levels of activities such as anti-bacterial, anti-cancer, anti-gout, anti-hepatitis, anti-hyperglycemic, anti-inflammatory, anti-leishmanicidic, anti-oxidant, anti-pyretic, anti-xanthine oxidase, choleretic, hemostatic, hypocholesterolemic, immunostimulatory and radioprotectant effects, etc.

Random amplified polymorphic DNA (RAPD) analysis was used to determine the genetic relationships among seventeen species of the Acanthopanax species. The DNA isolated from the leaves of the samples was used as template in polymerase chain reaction (PCR) with twenty random decamer primers in order to distinguish plant subspecies at the level of their genomes. The RAPD patterns were compared by calculating pairwise distances using Dice similarity index, and produced to the genetic similarity dendrogram by unweighted pair-group method arithmetic averaged (UPGMA) analysis, showing three groups; a major cluster(twelve species), minor cluster (4 species) and single-clustering species. The results of RAPD were compatible with the morphological classification, as well as the chemotaxonomic classification of the Acanthopanax species. The Acanthopanax species containing 3,4-seco-lupane type triterpene compounds in their leaves corresponded to the major cluster, another species having oleanane or normal lupane type constituents to minor clusters, and one species not containing triterpenoidal compound to single-cluster.

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.

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.

The content of chiisanoside in the Acanthopanax Species was determined by reversed-phase high performance liquid chromatographic method. Chiisanoside was separated from the other components in the plant extracts using Zorbax 300 SB $C_{18}$ column with gradient elution of acetonitrile. Identification of chiisanoside was carried out by comparison in the LC/MS spectrum of separated peak from extract with that of standard. By HPLC analysis in this experiment, Acanthopanax species could be classified into two groups based upon the content of chiisanoside-one with low concentration of chiisanoside, such as A. senticosus and A. koreanum, and another with high concentration of chiisanoside, such as A. senticosus f. inermis, A. Divaricatus var. albeofructus, and A. chiisanensis.

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.

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.
