This study was performed to investigate the anxiolytic effects of total sponin fraction from Ginseng Radix Rubra (KRG) in mice using the elevated plus-maze model. The water extract of KRG and ginseng total saponins (GTS) purified from the water extract of KRG were administered orally to mice. One hour after administration of KRG water extract and GTS, mice were tested on the elevated plus-maze. The water extract of KRG 100 mg/kg, and GTS 25 and 50 mg/kg did not increase open arm entries and time spent on open arm. However, GTS 100 mg/kg increased the number of open arm entries and time spent on open arm. On the other hand, as the plus-maze test was affected by changes in locomotor activity, an additional test was carried out with the specific aim of monitoring locomotor activity. The water extract of KRG 100 mg/kg, and GTS 25 and 50 mg/kg did not affect the locomotor activity. However, GTS 100 mg/kg significantly decreased locomotor activity. From this study, we suggest that GTS may play an imponant role on the anxiolytic effects in the plus-maze model.
