Ultrasound assisted methods for enhanced extraction of phenolic acids from quercus infectoria galls
Quercus Infectoria galls or known as Manjakani, is one of the potential herbs that have multiple therapeutic properties and are widely used in folklore medicine. Phenolic acids, including gallic acid and tannic acid, has been extracted from the galls by using different ultrasound extraction system (...
