Chemotaxonomy of Dictyotales (Phaeophyta). 3. The <I>Dictyopteris</I> and <I>Taonia</I> groups
Abstract
Brown algae of the "Dictyopteris" and "Taonia" groups have yielded about 30 terpenes that have been isolated from species of the genera Dictyopteris, Stypopodium and Taonia. Sesquiterpenes and diterpenes have been separated each into two chemical classes dipending on their biogenetic origin, mixed or not. Similarity coefficients following Sorensen have been calculated, and metabolites have been characterized by oxidation and skeleton indices. The mean values of these indices, calculated for each taxon, indicated that terpenes are suitable taxonomic markers and that the order Dictyotales should he divided into three families.Downloads
