Chemical profile of adults and buds of the chemically defended marine sponge Tethya maza

Publication date: June 2015 Source:Biochemical Systematics and Ecology, Volume 60 Author(s): Suzi Meneses Ribeiro , Renato Crespo Pereira Several adults and the corresponding larvae of marine sponges are known as rich sources of secondary metabolites. In this paper we will show the chemical profile of adults and buds of the sponge Tethya maza. Cholesterol, ergost-5,22-dienol-3, stigmast-5,24-dienol-3, cholest-5,22-dienol-3, cholest-5-enol-3-one-7, and stigmast-5,24(28)-dien-3-ol were the major compounds detected, two of them being detected only in crude extracts of the adults while one was present only in the buds. Due to this high similarity it is supposed that buds could be chemically protected with regards to predation as well as the adult individuals of T. maza. This is the first report of chemicals present in the structures (buds) of sponges produced by asexual reproduction.
