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.

Water extracts of Acanthopanax divaricatus var. albeofructus (ADA) fruits were used to treat hPBMC to determine the mechanisms for the immunomodulatory effects. The secretion level of various cytokines including Th-1 type (IL-2, L-12, $IFN-{\gamma}$ and $TNF-{\alpha}$) and Th-2 type (IL-6, IL-8 and IL-10) were measured using ELISA. A significant increase of Th-1 type cytokine secretion was observed in the presence of extract while Th-2 cytokine, IL-6 was suppressed. Our results suggest that ADA fruit extract may influence the anticancer immune responses towards a predominance of Th-1 cytokines in the immune system.

Ultraviolet (UV) A penetrates deeply into the skin and induces the generation of reactive oxygen species (ROS) causing damage to fibroblasts, which leads to aging of the skin. However, the body has developed an antioxidant defence system against the harmful effects of ROS. Enzymes such as superoxide dismutase (SOD) and catalase (CAT) play critical roles on the removal of excess ROS in living organisms. In this study, the antioxidant activities of anthocyanins (cyanidin 3-galactoside and cyanidin 3-lathyroside) from Acanthopanax divaricatus var. albeofructus (ADA) fruits were investigated by xylenol orange, thiobarbituric acid reactive substances (TBARS), and antioxidant enzyme assay. As a result, generation of $H_2O_2$ and lipid peroxide induced by UVA-irradiation in human dermal fibroblast (HDF-N) cells was reduced by treatment of anthocyanins. Also, augmented enzyme (SOD and CAT) activities were observed in UVA-irradiated cells when treated with anthocyanin. In conclusion, the results obtained show that anthocyanins from ADA fruits are potential candidates for the protection of fibroblast against the damaging effects of UVA irradiation. Furthermore, anthocyanin may be a good candidate for antioxidant agent development.

Acanthopanax species have traditionally been used as a tonic, a sedative as well as in the treatment of rheumatism, hypertension and diabetes. In the present study, oxidative stress was induced in Vero cells by incubating the cells with glucose and the cell viability was measured by MTT assay. The concentration of glucose which 50% of cell viability was 125 mM $(IC_{50})$ and the cell viability was increased to $87.6{\pm}8.8%$ by treatment of the extracts of Acanthopanax divaricatus var. albeofructus. The antioxidative activity of water extract of different parts of the Acanthopanax plant was investigated by DPPH (1,1-diphenyl-2-picrylhydrazyl) assay, xylenol orange assay, TBARS (thiobarbituric acid reactive substances) assay and enzyme (superoxide anion and catalase) assay. Each extract (leaves, root, stem and fruits) of the plant showed free radical and $H_2O_2$ scavenging activity. The extract also inhibited lipid peroxidation and recovered enzyme (superoxide anion dismutase and catalase) activity in Vero cells treated with glucose.
