Kang, Qiaozhen published the artcileComparison on characterization and antioxidant activity of polysaccharides from Ganoderma lucidum by ultrasound and conventional extraction, Product Details of C6H12O6, the main research area is Ganoderma polysaccharide antioxidant ultrasound conventional extraction; Ganoderma lucidum polysaccharide; Hot water extraction; Ultrasound assisted extraction.
The polysaccharides of Ganoderma lucidum (GLP) extracted by the methods of ultrasound assisted extraction (UAE) and hot water extraction (HWE) were characterized and the antioxidant activities of GLPUAE and GLPHWE were compared. High performance gel permeation chromatog. (HPGPC) showed that the average mol. weight of GLPUAE and GLPHWE were 465.65 kDa and 703.45 kDa, resp. GLPUAE was composed of mannose, rhamnose, glucose, galactose and arabinose in the molar ratio of 2.58:1.25:11.17:2.5:1, while GLPHWE was composed of the same monosaccharide in the ratio of 3.11:1.11:19.44:2.33:1. GLPHWE showed a relatively higher antioxidant activity than GLPUAE by testing the reducing power, the scavenging ability on 1.1-diphenyl-2-picryl-hydrazyl (DPPH), hydroxyl radical and cellular protective effect on yeast cells from UV radiation (UV) damage. GLPUAE and GLPHWE were purified by chromatog. column of DEAE-52 cellulose. GLPUAE, GLPHWE and the purified components could be novel antioxidants for functional food.
