AIM: Ginsenosides, a class of ginseng compounds of herbal medicine, have been shown to have therapeutic potential for the neuroprotection of brain damage after cerebral ischemia because of their activities including anti-oxidant and anti-inflammation. In the elderly population, aging-induced oxidative stress has been implicated in exacerbating brain injury, which might also be ameliorated by anti-oxidants, such as ginsenosides. However, this hypothesis has yet to be explored.

METHODS: Here we present in vivo studies highlighting a protective function of ginsenoside Rb1, a natural steroid glycoside derivative purified from saponin of Panax ginseng, in neurological injury during aging.

RESULTS: Compared with young mice, the recovery of brain damage after middle cerebral artery occlusion is significantly impaired in aged mice, whereas the long-term pretreatment with ginsenoside Rb1 through oral administration can greatly prevent the injury in a dose-dependent manner. In addition, we further explored the involvement of oxidative stress and extracellular signal-regulated kinase activation in aged mice stimulated by cerebral ischemia, both of which were found to be blocked by ginsenoside Rb1.

CONCLUSIONS: These observations suggest that ginsenoside Rb1 could represent promising applications as anti-oxidants for the anti-aging treatment of neurological disorders, such as stroke, in elderly patients. Geriatr Gerontol Int 2017; 17: 338-345.
