Abstract

The Duquénois test is employed throughout the world as part of the identification procedure for cannabis. A survey of results published for more than 400 herbally derived and botanical materials originating from some 270 different plant species is presented. A survey of results from some 200 organic compounds is also presented. The data show that the D-L modification is the most specific. There is no published report of an obviously botanical material, apart from cannabis, that gives a positive D-L test. Apart from cannabinoids, some resorcinol derivatives give a positive test. All of the materials are easily distinguished from cannabis by TLC.
