Secondary metabolite chemistry of the caribbean marine alga Sporochnus bolleanus: A basis for herbivore chemical defence

Cryptothecia aleurodes was considered to be a widespread, rare tropical lichen having white ascigerous areas and a crustose whitish-grey thallus containing norstictic acid. A revision of its type specimen from Guadeloupe and the study of recent specimens from Martinique proved that the species has been misunderstood. In this paper, Cryptothecia aleurodes is shown to have a K– and C+ red thallus containing notably gyrophoric acid as major secondary metabolite but lacking norstictic acid. A detailed description and illustrations are provided. The species is known with certainty only from the Caribbean and has probably a Neotropical distribution. Previous reports of C. aleurodes from the Seychelles and Thailand are shown to be misidentifications and reports from India are considered dubious.

The green seaweed Caulerpa brownii (Chlorophyta, Caulerpaceae) occurs in Tasmania in two morphological forms (branched and unbranched) and each form has a different profile of diterpenoid secondary metabolites. Unbranched specimens gave rise to the novel secondary metabolites 11, 13, 14, 17, and 18, the secondary metabolite 8 that has been isolated for the first time as a natural product, as well as the known compounds 1 and 3–7. Branched specimens of C. brownii yielded the novel terpenoid esters 21 and the known compounds 1 and 2.
