Abstract
Fourier transform ion cyclotron resonance (FT-ICR) and matrix assisted laser desorption ionization (MALDI) mass spectrometry are used to systematically study ulmic acid extracts taken from a sediment sample in the Gulf of Mexico. The sample, which is extracted with methanol, is taken from the ecosystem of the bryozoan Bugula neritina. Ulmic acid is a loosely defined group of molecules that are the alcohol extracts of naturally occurring organic matter. The FT-ICR analysis focuses on carbon compounds C16-C24 and C35. C35 is examined by FT-ICR because its structure may represent the bryophan ring, the central structural feature in all bryostatins.
