Variation of brominated indoles and terpenoids within single and different colonies of the marine bryozoan Flustra foliacea.
???displayArticle.abstract???
The variation of the brominated indole and diterpenoid content within single and different colonies of the bryozoan Flustra foliacea was investigated. The secondary metabolite profile and concentrations of individual components of F. foliacea samples were established using GC-MS. Samples from 17 different collecting sites were analyzed. The alkaloid and diterpene composition of F. foliacea varied greatly depending upon the site of collection. Investigation of F. foliacea samples from a single site (Helgoland, North Sea) over a period of time showed that the alkaloid and diterpenoid profile remained constant, however concentrations of individual components varied significantly. The alkaloid and diterpenoid composition of different segments of a single colony was found to be constant. Only small differences could be detected in the essential oil composition of different colonies and segments of single colonies of F. foliacea. Two of the F. foliacea alkaloids were found in the gastropods Hydrobia ulva and Gibbula cinerea, and one alkaloid in the common starfish Asteria rubens, all collected from the surface of the bryozoan.
