Extension of axons and dendrites in neurons may compensate for and repair damaged neuronal networks in the dementia brain. To find out drugs capable of regenerating the neuronal network, we focused on several herbal drugs belonging to the genus Panax, kinds of Ginseng, and investigated neurite outgrowth activity of their extracts and compounds. We found that the methanol extracts of Ginseng (root of P. ginseng), Notoginseng (root of P. notoginseng) and Ye-Sanchi in Chinese (rhizome of a relative to P. vietnamensis) increased neurite outgrowth in SK-N-SH cells. The protopanaxadiol-type saponins, ginsenosides Rb1 and Rb3, and notoginsenosides R4 and Fa isolated from Ye-Sanchi extract extended neurites, while protopanaxatriol-, ocotillol- and oleanane-type saponins had no effect on the neurite outgrowth. The percentage of cells with multipolar neurites and number of varicosities were intensely high in cells treated with the methanol extract of Ye-Sanchi as well as ginsenosides Rb1 and Rb3, and notoginsenosides R4 and Fa. Both phosphorylated NF-H-expressing neurites and MAP2-expressing ones were extended by treatment with those saponins and the extract. Especially, longer neurites were mainly positive for phosphorylated NF-H. These results suggest that protopanaxadiol-type saponins enhance axonal and dendritic formation activity.<br>
