摘要：

Photodegradation of chlorophyll-a in seawater leads to the formation of some relatively stable photoproducts, acidic or alkaline hydrolysis of which affords 6,10,14-trimethylpentadecan-2-one. Owing to their high polarity, these compounds are not extracted during Soxhlet extraction of sediments with chloroform, but can be recovered in part in the form of 6,10,14-trimethylpentadecan-2-one after acidic and alkaline hydrolysis of the Soxhlet extraction residues. Hence, we suggest the use of this "bound" ketone as a marker for the photodegradation of chlorophylls with a phytol ester group in the marine environment.
