Isolation and hypoglycemic activity of panaxans I, J, K and L, glycans of Panax ginseng roots

From an aqueous extract of the Oriental crude drug "ninjin" (ginseng), Panax ginseng roots from Korea, four glycans, panaxans I, J, K and L, have been isolated. These components remarkably reduced blood sugar levels in normal and alloxan-induced hyperglycemic mice.
