The Effects of Ultrasound on the Extraction, Physicochemical Properties and Antioxidant Activities of Polysaccharide From Ganoderma Atrum Check Access

Ganoderma (G.) is a famous medicinal fungus found in the regions of China, Japan, Korea, and Eastern Russia, and the polysaccharide from G. atrum (PSG) – one of the most important species of Ganodermataceae – has been shown to possess excellent bioactivity. Ultrasonic treatment has been widely used to improve the yield recovery, physicochemical properties and bioactivity of polysaccharides. In order to improve the yield recovery and modify the molecular structure of PSG, the authors employed the ultrasonic technique and assessed its effects on structure, physicochemical properties and antioxidant activity of PSG.
