Screening and Isolation of Antibiotics Resistance Inhibitors from Herb Materials II - Inhibitory Effects of 'Chwinamool' (Aster scaber)

Repeated column chromatographic works of hexane fraction of Aster scaber afforded some volatile mixtures of two or three components, which process potent inhibitory activity(more than 90% of control at $50{\mu}g/ml$) to the resistance of multi-drug resistant Staphylococcus aureus SA2 when combined with chlorampenicol($50{\mu}g/ml$).
