Description
Four authors compare ways of extracting essential oil from Salvia fruticosa, a sage used in Egypt for stomach complaints, and test how well each oil fights gut bacteria. Fresh plants were processed by steam distillation or by headspace capture, while dried plants went through supercritical fluid extraction. The team then measured each oil's makeup and its effect on six bacterial strains linked to gut illness.
The supercritical method gave the most oil, at 0.6 milliliters per 100 grams. The steam and supercritical oils were rich in oxygenated compounds, while the headspace oil held mostly non-oxygenated ones. Eucalyptol dominated the first two oils, while the supercritical oil featured different main components. Both the steam and supercritical oils killed bacteria at rates close to the control in time-kill tests, showing real antibacterial promise.
