The Alkaloids of <i>Cryptocasrya bowiei</i> (Hook.) Druce

Abstract

Two closely related water-soluble alkaloids cryptaustoline and cryptowoline iodides have been isolated from the bark of Cryptocarya bowiei (Hook.) Druce. Both have been shown to be derivatives of dibenzo[b,g]pyrrocoline. This constitutes the first isolation of substances containing this nucleus from natural sources.
