Abstract

The ether extract of the New Zealand liverwort Radula marginata afforded a new cannabinoid type bibenzyl compound named perrottetinenic acid, and two new bibenzyls, together with a known cannabinoid, perrottetinene. Their structures were established by two dimensional (2D) NMR spectral data. The structure of perrottetinenic acid was a similar to that of Δ1-tetrahydrocannabinol, a known hallucinogen. Cannabinoid type bibenzyls have been isolated from liverwort Radula perrottetii, though have not previously been reported from the liverwort R. marginata.
