Triterpenoid saponin from increases the sensitivity of methicillin-resistant to β-lactam and aminoglycoside antibiotics.

The triterpenoid saponins, ginsenosides, are the major bioactive compound of red ginseng and can exert various physiological activities. In the present study, we examined whether red ginseng extract (RGE) exerts antibacterial activity against methicillin-resistant (MRSA). RGE had no bactericidal activity, at least in the range of dissolvable concentration.
