Isolation and Hypoglycemic Activity of Ganoderans A and B, Glycans of Ganoderma lucidum Fruit Bodies
26 February 2007 (online)
A water extract of the Oriental crude drug “reishi”, the fruit bodies of Ganoderma lucidum, significantly decreased plasma sugar level in mice. Fractionation of the extract by monitoring the hypoglycemic activity afforded two glycans, ganoderans A and B. These glycans elicited remarkable hypoglycemic actions in normal and alloxan-induced hyperglycemic mice.
