Isolation and Hypoglycemic Activity of Ganoderans A and B, Glycans ofGanoderma lucidumFruit Bodies

Abstract
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. 1 Antidiabetes drugs, Part 9. Also Part 91 in the validity of the Oriental medicines
