Acanthopanax senticosus has been used in East Asia as a traditional medicine. The purpose of this study is the investigation of an extraction method for A. senticosus var subinermis (ASvS) leaves to improve their antioxidant and anti-inflammatory activities. Six extracts were prepared: extracted with water (W), ethanol (Eth), water or ethanol after ultra high pressure (WP, EthP), and water or ethanol after an extrusion process (WEx, EthEx). Diphenylpicrylhydrazyl (DPPH) radical scavenging activity and ferric reducing ability showed that all extracts had a significant antioxidant activity. In anti-inflammatory activities, Eth and EthEx significantly inhibited the release of lipopolysaccharide (LPS)-induced nitric oxide (NO), tumor necrosis factor (TNF)-${\alpha}$, and interleukin (IL)-$1{\beta}$ independent of cell viability in RAW 264.7 macrophage cells. Inducible NO synthase (iNOS) protein was significantly decreased by EthEx. These findings present that Eth and EthEx extracts of ASvS leaves have anti-inflammatory activities, and EthEx extract suppresses LPS-induced NO through the down-regulation of iNOS and pro-inflammatory cytokines.

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 present study was carried out to investigate the changes in essential oil contents as a part of searching the changes in active components in the graft cultivation of A. senticosus. To increase the yield of aerial parts and the contents of active components of Acanthopanax senticosus, scions of A. senticosus were grafted on different rootstocks. As a result, the contents of calarene, ${\alpha}-beramotene$ and spathulenol increased, but cis-caryophyllene and epizonarene contents decreased. ${\beta}-pinene$, ${\beta}-myrcene$, 2,5,5 -trimethyl-1, 3, 6-heptatriene and ${\beta}-elemene$ were not detected in the leaves of grafted A. senticosus. Essential oils from stems did not differ with the methods of cultivation. Oil contents of 3-year-old plants were higher than those of 1-year-old plants, whereas ${\alpha}-bergamotene$ content(27%) was highest in the stem of grafted A. senticosus(27%). Ethylbenzene, 2-furancarboxaldehyde, M134 $(t_R=2.11)$ and M205 $(t_R=3.16)$ disappeared in the roots of A. senticosus var. subinermis, but 6,6-dimethyl-3-methylenebicycloheptane, M166 $(t_R=1.82)$, and (+) -aromadendrene and ${\beta}-bisabolene$ were newly found.
