摘要：

The identities of the two major tetrapyrroles in the bottom sediment of a eutrophic lake, assigned previously by spectral comparison with standards, have been confirmed as phaeophytin a and pyrophaeophytin a through the use of 2D COSY and nOe difference NMR techniques. This provides the first unambiguous characterization of sedimentary chlorins, the components being early products in the degradative pathway of chlorophyll a in the aquatic environment.
