Resumo:
A novel sedimentary transformation product of chlorophyll, purpurin-7 phytyl ester, has been identified by atmo- spheric pressure chemical ionisation liquid chromatography mass-spectrometry in sediments from Lake Baikal, Russia, Loch Ness and Priest Pot, UK. This product of oxidative transformation is an intermediate on the transformation pathway leading to sedimentary aetioporphyrins and its occurrence lends strong support to the view that aetiopor- phyrins derive mainly from precursor chlorophylls.
