Identification of Fatty Acids, Amides and Cinnamic Acid Derivatives in Supercritical-CO Extracts of Leaves Using UPLC-Q-TOF-MS Combined with Chemometrics.

leaf (CTL), also known as Indian bay leaf, is used all over the world for seasoning, flavoring, and medicinal purposes. These characteristics could be explained by the presence of several essential bioactive substances and lipid derivatives. In this work, rapid screening and identification of the chemical compounds in supercritical (SC)-CO extracts of CTL by use of UPLC-Q-TOF-MSE with a multivariate statistical analysis approach was established in both negative and positive mode.

Potentiation of antimicrobial activity of ciprofloxacin by Pelargonium graveolens essential oil against selected uropathogens.

The recent approach of using herbs and antibiotics in combination constitutes a strategy to overcome the problems of resistance and side effects associated with conventional antibiotics. In the present study, the antimicrobial effect of Pelargonium graveolens L' Hér essential oil in combination with ciprofloxacin was evaluated on uropathogens, namely, Klebsiella pneumoniae KT2, Proteus mirabilis PRT3 and Staphylococcus aureus ST2. Minimum inhibitory concentrations of P.
