Canadian Propolis Promising Source of Biologically Active Substances

Chemical Composition of Propolis from Canada, Its Antiradical Activity and Plant Origin
Natural Product Research, 2006 May 20;20(6):531-6

The chemical composition of propolis from two regions in Canada was studied: Boreal forest and Pacific coastal forest that lay outside the area of distribution of Aigeiros poplars, the usual propolis source plants…

Both samples showed good radical scavenging activity against DPPH. Obviously, Northern type propolis is a promising potential source of biologically active substances and deserves further investigation.
