| Abstract | |
Petiveria alliacea L. (Petiveriaceae), a medicinal plant found in tropical regions of South and Central America, the Caribbean, and Africa, is mainly used to treat inflammatory process and respiratory problems. In this study, we have evaluated the antibacterial activity of P. alliacea crude extract and fractions, investigated the chemical composition, and developed and validated a simple method to quantify flavanones. To verify the antibacterial activity, we determined the minimum inhibitory concentration (MIC) against Staphylococcus aureus and Escherichia coli. Phytochemical investigations were carried out by chromatographic and spectroscopic analysis. To quantify astilbin and engeletin, we developed a method based on HPLC coupled to a diode array detector (DAD) and validated it. The P. alliacea crude extracts and fractions exhibited MIC ranged from 10 to 25 mg/mL. Chemical investigation of P. alliacea revealed the presence of trans-N-methyl-4-methoxyproline (1), ethyl-beta-galactoside (2), ethyl-alpha-galactoside (3), and ethyl-beta-fructofuranoside (4). The developed HPLC-DAD method proved suitable for determining flavonoids in P. alliacea: it presented good linearity, specificity, and satisfactory accuracy and precision. The developed HPLC-DAD method can quantify the P. alliacea chemical markers. The isolated compounds (2-4) have been described in P. alliacea for the first time. (AU) | |
