Supercritical fluid CO2 extraction of essential oil from Marchantia convoluta: global yields and extract chemical composition
The essential oil of Marchantia convoluta was obtained by supercritical (carbon dioxide) extraction using methanol as a modifier. Global yields were determined according to the orthogonal design. The effects of different parameters, such as pressure, temperature, modifier volume and extraction time, on the supercritical fluid extraction (SFE) of essential oil from M. convoluta were investigated...
متن کاملAntibacterial Activityand Comparison of the Volatile Oils of Tanacetum tenuisectum (Boiss.) Podl. Obtained by Three Different Methods of Extraction
The essential oils obtained by hydrodistillation (HD), steam distillation (SD) and solvent free microwave extraction (SFME) from the stems and flowers of Tanacetum tenuisectum (Boiss.) Podl., which is endemic to Iran,were analyzed by GC and GC/MS.Camphor (26.9 %, 27.2% and 25.5%), borneol (12.6%, 11.5% and 7.6%) and 1, 8-cineole (7.9%, 13.2% and 11.3%) were the main constituents of the HD, SD a...
