Acanthopanax sessiliflorum of family of Araliaceae, Korean wild plant was first described by T. $N_{AKAI}$ in 1909. Although Acanthopanax has been formerly classified by 2 genera, 8 species, but it could be rearranged by 1 genus, 7 species. A. sessiliflorum among 7 species was distributed almost all over the country and A. senticosus was available mainly in the northern part and distribution of A. senticosus was coming down southward alongside Mt. Taibaik and Mt. Sobaik from North. A. chiisanense was mainly distributed over the southern part in the middle area, and the other 4 species were rarely distributed in limited places.

The contents of bioactive and antioxidative activities (DPPH (${\alpha},{\alpha}'$-diphenyl-${\beta}$-picrylhydrazyl), free radical scavenging activity, peroxidation of linoleic acid and rat hepatocyte microsome, and Fe/Cu reducing power, tyrosinase inhibition activity) were tested by in vitro experimental models using water, hot water, ethanol and methanol extracts of leaves (ASL), roots (ASR), stems (ASS) and fruits (ASF) from Acanthopanax senticosus. Hot water extract from ASL showed the highest extraction yield (16.04%) as well as highest contents of phenolic compounds (2.67%) and flavonoids (1.43%). Major minerals were K, Ca and Mg. In oxidation in vitro models using DPPH free radical scavenging activity, Fe/Cu reducing power, $Fe^{2+}$/ascorbate-induced linoleic acid peroxidation by ferric thiocyanate and thiobarbituric acid (TBA) methods, tyrosinase inhibition activity and autooxidation of rat hepatic microsomes membrane, and antioxidative activities were strong in Acanthopanax senticosus. From these results, ASL extracts were shown to have the most potent antioxidative properties and contain the highest amounts of antioxidative compounds such as phenolic compounds and flavonoids. These results may provide the basic data to understand the biological activities of bio-active materials derived from leaves of Acanthopanax senticosus.

The anti-oxidant activities of Acanthopanax senticosus stems were investigated. The n-BuOH fraction of A. senticosus stems exhibited a significant decrease in serum transaminase activities elevated by hepatic damage induced by CCl$_4$-intoxication in rats. The n-BuOH fraction inhibited the sGPT activities by 65.79%. The n-BuOH fraction showed the increase in the anti-oxidant enzymes such as hepatic cytoso1ic superoxide dismutase, catalase and glutathione peroxidase activities by 30.31, 19.82 and 155%, respectively, in CCl$_4$-intoxicated rats. These results suggest that the stems of A. senticosus possess not only the hepatoprotective, but also the anti-oxidant activities in rats.

The genetic analyses of Acanthopanax senticosus Harms from Korea, China and Russia, were made by comparing the internal transcribed spacer (ITS) sequences of the nuclear ribosomal DNA. The ITS region of A. senticosus was amplified by polymerase chain reaction (PCR) using the universal primers and then directly sequenced. The length of the ITS region including 162 bp 5.85 rRNA gene ranged from 608 bp (for Korean and Chinese) to 611 bp (for Russian). The G+C content of ITS region were 60.20% for Korean and Chinese plants and 60.06% for Russian plants. Sequence comparisons indicated that ITS regions of A. senticosus from Korea and China were identical, whereas the ITS sequence of A. senticosus from Russia showed 99.2% homology with the plants from Korea. Variation in sequences were attributable to 5 bp substitution such as transversion or insertion events. These results suggested that A. senticosus Harms from Korea and China were closely related in phylogenetic relationship compared to Russian. In addition, A. senticosus Harms were more similar to Kalopanax pictus than A. sessiliflorus in their ITS sequences.

Hepatic ischemia-reperfusion injury (HIRI) is linked with high mortality rate. Several agents have been developed so far to reduce the risk of HIRI. In this study, we investigated the effects of Acanthopanax senticosus extract (AS) on hepatic ischemia-reperfusion. To explore the protective effects of A. senticosus extract injection (ASI) on hepatic ischemia-reperfusion injury rats animal model were used. After the development of HIRI by using clamping method rats were then randomly divided into five groups. Different doses of AS were administered in HIRI rat model. The level of ALT, AST, and MDA content in serum were detected in sham and HIRI groups. The activity of SOD, MPO and $Ca^{2+}-ATPase$, content of MDA, and cAMP in hepatic tissue were also measured. Expression of Bcl-2 and Bax protein were detected by immunohistochemical staining method. Compared with sham group, ASI has the protective effect on the HIRI model in rats. Blood levels of ALT, AST, SOD, MPO, and MDA were significantly lower in ASI group compared with HIRI. Indeed SOD and $Ca^{2+}-ATPase$ activities, MDA content, and cAMP level were improved in ASI group. Furthermore, Bcl-2 and Bax protein were improved in ASI group compared with only HIRI group. These results suggest that AS may provide potential ameliorative therapy by inhibiting the damage signaling mechanism in hepatic ischemia/reperfusion injury model.

The antioxidant activities of Acanthopanax senticosus stems were evaluated in $CCl_4$-intoxicated rats. The n-butanol fraction from the water extract of the stems, when pretreated orally at 200 mg/kg/day for 7 consecutive days in rats, was demonstrated to exhibit significant increases in antioxidant enzyme activities such as hepatic cytosolic superoxide dismutase, catalase and glutathione peroxidase by 30.31, 19.82 and 155%, respectively. The n-butanol fraction whereas showed a significant inhibition of serum GPT activity (65.79% inhibition) elevated with hepatic damage induced by $CCl_4$-intoxication. Eleutheroside B, a lignan component, isolated from the n-butanol fraction was found to cause a moderate free radical scavenging effection DPPH, its scavenging potency as indicated in $IC_{50}$ value, being 58.5$\mu$ M. These results suggested that the stems of A. senticosus possess not only antioxidant but also hepatoprotective activities.

In this study, we optimized conditions for extraction of eleutherosides B and E from stem powder of Acanthopanax. To enhance eleutheroside B and E yields, Acanthopanax sessiliflorus Seeman and Eleutherococcus senticosus Maxim were pre-incubated with the following enzymes: Celluclast, Viscozyme L, Lactozyme, Lecitase, and Novozyme 33095. Treatment with Novozyme 33095, a commercial pectinase, for 3 h resulted in the highest yields of eleutherosides B and E from A. sessiliflorus and E. senticosus. Compared with extraction at $121^{\circ}C$ for 120 min, at $121^{\circ}C$ for 15 min after Novozyme 33095 pre-incubation increased eleutheroside B and E yields from A. sessiliflorus by 7% and 17%, respectively. In the case of E. senticosus, eleutheroside B and E yields increased by 25% and 29%, respectively.

This study examined the effects of four herbal sports drinks containing Prunus mume, Liriope platyphylla, and Acanthopanax senticosus fruit extracts on body fat and endurance of rats trained by a progressive loaded exercise program. Forty male Sprague-Dawley rats (6 weeks old) were divided into five groups and fed experimental diets for 6 weeks according to the following protocol: C, exercise-trained control group (n=8); A, exercise group with Acanthopanax senticosus extract (n=8); L, exercise group with Liriope platyphylla extract (n=8); PA, exercise group with Prunus mune fruit extract plus Acanthopanax senticosus extract (n=8); PL, exercise group with Prunus mune fruit extract plus Liriope platyphylla extract (n=8). Endurance was measured by a progressive loaded exercise test using a treadmill. PA and PL supplementation significantly extended time to exhaustion compared to the control group (p<0.05). Further, the four herbal sports drinks all significantly reduced epididymal and interscapular white adipose tissue weights compared to the control group (p<0.05). Plasma triglyceride concentration was significantly lower in the A group compared to the control group. Plasma free fatty acid concentration was higher in the A group compared to the control group. On the other hand, Acanthopanax senticosus fruit extract supplementation tended to reduce the plasma glucose concentration compared to the control group. PA and PL supplementation significantly increased gastrocnemius muscle LDH activities compared to the control group (p<0.05). These results show that sports drink containing Acanthopanax senticosus improved endurance capacity, plasma lipids, and glucose concentrations. Sports drink with Prunus mume and Liriope platyphylla or Acanthopanax senticosus was synergistically improved endurance.

When 10 kinds of herbal medicines were fractionated into hexane, MeOH, cold-water, and hot-water extracts, hot-water extracts from Acanthopanax senticosus (AS), Glycyrrhiza uralensis (GU), Cichorium intybus (CI), and Polygonatum odoratum (PO) showed the potent intestinal immune system modulating activity (1.72-, 1.62-, 1.60-, and 1.53-fold of control at $100{\mu}g/mL$, respectively). Especially, hot-water extracts from AS (215% compared with the control) and GU (187%) also had macrophages stimulating activity and mitogenic activity of splenocytes (7.1- and 6.5-fold) at $100{\mu}g/mL$. In addition, the effects of hot-water extracts from herbal medicines on anticancer activities were studied in mice. Hot-water extracts from AS and GU enhanced cytotoxicity of natural killer cell against cancer cell, Yac-1 (37 and 34% cytotoxicity) at E/T ratio 100:1, and colon 26-M3.1 cancer cell lines had significantly inhibited (82.1 and 75.2%) in experimental lung metastasis. These results suggest that hot-water extracts from A. senticosus and G. uralensis can be used as biological response modifiers to stimulate immune system and inhibit tumor.
