Eleutherococcus senticosus (also called Acanthopanax senticosus), belonging to Araliaceae family, has been used as an important medicinal woody plant. Mature seeds of Eleutherococcus senticosus have rudimentary (extremely immature) zygotic embryos and require a long-term stratification for about 18 months to induce germination. Here, through the methods of endosperm removal and other exogenous treatments, we investigated the factors for inducing rudimentary embryos by in vitro culture, Rudimentary zygotic embryos in seeds were at globular to heart-shaped stage at about $250{\mu}m$ in length just after harvest of fruits. When the seeds without testa were cultured on 1/2 MS (Murashige and Skoog 1962) medium, they did not germinate regardless of medium and sucrose concentrations but the removal of endosperm tissue markedly stimulated the growth of rudimentary zygotic embryos. The embryo reached ear-lier maturation, once when the endosperm surrounding the rudimentary embryos was removed. Rudimentary zygotic embryos developed cotyledons within 3 weeks of culture after endosperm emoval. However, post-mature zygotic embryos failed to germinate though they were morphologically normal, indicating another dormancy of embryos. $GA_3\;(2.0\;\cal{mg/L})$ and/or charcoal ($0.2\%$) treatment rapidly enhanced the germination of zygotic embryos. These results suggest that E. senticosus seeds have double dormancy; i. e. morphological rudimentary dormancy influenced by surrounding endosperm and physiological dormancy after post-maturation of zygotic embryos. Based on the above findings, we established the rapid germination of rudimentary zygotic embryos by in vitro culture of excised seeds with endosperm removal and $GA_3$ treatment.

Ethanol and butanol fractionation of E. senticosus showed strong anti-oxidant activity, and methanol and water extracts also had high anti-oxidant activity. The anti-oxidant activities in ethanol and butanol fractionation were higher than or similar to those of ${\alpha}-tocopherol$. The cytotoxic effect of root extract of E. senticosus was evaluated on seven different human cancer cell lines, The extracts of leaf and stem of E. senticosus also had strong antioxidant activity, but the antioxidant activity in root extract was higher than those in leaf and stem extracts. Methanol, hexane, and aqueous fraction layer had much higher inhibitory activities on lipid peroxidation in rat liver microsomes compared with ${\alpha}-tocopherol$. The effect of root extract of E. senticosus was evaluated on six human cancer cell lines. The values of 50% growth inhibition $(GI_{50})$ for the extracts were mostly below $30{\mu}g/ml$, and the extracts are considered as active inhibitory compounds on cancer cells.

Eleutherococcus senticosus is a typical oriental folk medicinal herb. It has been used clinically as a anti-rheumatic disease, anti-stress, ischemic heart disease and gastric ulcer. In the present study, we examined the adjuvant activity of the crude polysaccharides fraction from Eleutherococcus senticosus, EN-3, on the induction of humoral and cellular immune responses against bovine serum albumin (BSA) or ovalbumin (OVA). The thioglycollate-induced macrophages and silica-induced dendritic-like cells cultured with BSA and EN-3 synergistically increased the production of TNF-$\alpha$ and IL-12. When mice were subcutaneously immunized with BSA + EN-3, the antibody titer against BSA was showed significantly higher than those immunized with BSA alone. In addition, when mice were immunized with OVA + FIA + EN-3, the antibody titer was showed similar patterns with the FCA. The assay for determining subisotype of antibody revealed that EN-3 augmented OVA-specific antibody titer of IgG1 and IgG2b. The culture supernatant obtained from splenocytes of mice treated with OVA + FIA + EN-3 also showed a higher level of both OVA-specific Th1-type (IL-2, IFN-${\gamma}$ and GM-CSF) and Th2-type cytokine (IL-4, IL-6 and IL-10). In vitro analysis of T cell proliferation to OVA on 8 weeks, the splenocytes of mice treated with OVA + EN-3 showed a significantly higher proliferating activity than those treated with OVA alone. These results suggest that EN-3 may possess adjuvant activities to potentially to enhance humoral as well as cellular immune response.

We performed the present study to investigate whether Rehmannia glutinosa Libosch (RG) extracts (RGX) and Eleutherococcus senticosus Max (ES) extracts (ESX) play any roles in bone metabolism. We examined cellular activities of bone cells by measurement of osteoblastic cell viability, osteoprotegerin (OPG) secretion from osteoblasts, osteoclastogenesis, and osteoclastic activity. There is no cytotoxicity from osteoblasts after treatment with RGX and ESX. The secretion of OPG from the osteoblasts showed marked increases after treatment with RGX and ESX. In addition, RGX and ESX treatment decreased the number of tartrate-resistant acid phosphatase-positive multinucleated cells and the resorption areas. RGX and ESX, when mixed at optimal ratios, induced synergic effects, in vitro. OPB, which showed synergic effects, is the extract of natural ingredients RG and ES mixed at a raw material weight ratio of 4 : 1. It can be suspected that extracts of RG and ES mixtures contains active ingredients involved in bone tissue metabolism and may be effective in improving osteoporosis.
