A nonpolar chlorophyll c‐ like pigment was isolated by semi‐preparative high performance liquid chromatography from the coccolithophorid Emiliania huxleyi (Lohm.) Hay and Mohler. The visible absorption spectrum of this pigment was similar to that of chlorophyll c 2 . However, its nonpolar chromatographic properties were quite different from those of the relatively polar chlorophylls c 2 and c 3 in E. huxleyi and similar to those of chlorophyll a. Analyses by gas chromatography and gas chromatography‐mass spectrometry showed that the nonpolar character of this new chlorophyll c was due to the presence of phytol, most likely on the acid side chain of the porphyrin macro‐cycle. This is the first example of a phytol‐substituted chlorophyll c ‐like pigment.
