Abstract
in a concentration-dependent manner. All of these results demonstrated that the ultrasound-assisted cellulase hydrolysis extraction of the total polyphenols and the proposed three-step separation of RosA and CafA gave high yields and good purity, and they exhibited effective antibacterial ability.
