Fatsia japonica is grown wild to Eastern Asia, including Korea, Japan, and Taiwan and it is known as ornamental plant, and it is also known that pharmacological action. In this study, we have selected the stem of F. japonica with consideration about biological activities and amount of yield. In addition, four compounds (1-4) were isolated from the stem of F. japonica. Extensive spectroscopic and chemical studies established the structures of these compounds as maltose (1), begoniifolide A (2), leiyemudanoside B (3), leonticin F (4). All of the compounds were investigated for their anti-inflammatory, anti-neuroinflammatory, and neuro-protective effects on RAW264.7, BV2, and HT22 cells. However, among four compounds, there were no effects by maltose (1), begoniifolide A (2), leiyemudanoside B (3), leonticin F (4) on the anti-inflammatory, anti-neuroinflammatory, and neuro-protective action. This is the first report on the isolation of maltose (1), begoniifolide A (2), leiyemudanoside B (3), leonticin F (4) from the stem of F. japonica. Begoniifolide A (2), leiyemudanoside B (3), leonticin F (4) were isolated for the first time from this plant. It might be necessary to continue the further studies to find the biological active compounds isolated from the stem of F. japonica.
