Ultrasonic-assisted extraction of condensed tannin from acron, gland, leaf and gall of oak using response surface methodology

Ultrasonic technology and response surface methodology (RSM) wereused for optimization of extraction of condensed tannins from the leaf, acron, gland and gall of oak. Three independent variables such as solvent percentage (%), temperature (°C) and time (min) were studied. Effect of methanol concentration was found to be significant on all responses. Optimal ultrasonicassisted extraction (UAE) c...

Optimization of Ultrasonic-Assisted Extraction of Natural Antioxidants from Elaegnus Angustifolia Using Response Surface Methodlogy

Restrictions on the use of synthetic antioxidant such as butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) are being imposed because of their carcinogecity. In this investigation optimization of phenolic extraction process frome methanolic (80%) extract (v/v) of elaegnus angustifolia through Response Surface Methodology by fulin cio- calteu is performrd for op...
