摘要：

Chlorophyll degradation products incorporated into solvent-extractable high molecular weight material and into material which is only accessible with strong acid are identified. In surface sediment, the acid-extractable chlorophyll degradation products and the solvent-extractable high molecular weight chlorophyll degradation products each comprise approx. 30% of total sedimentary chlorophyll degradation products. In the high molecular weight phorbin fraction, only phorbins derived from chlorophyll a were identified, whereas in the acid-extractable material, porphyrins as well as phorbins derived from chlorophyll a were identified. The acid-extractable fraction contains approximately one-half the amount of porphyrins and phorbins as does the solvent-extractable material.
