Characterization of [8-ethyl]-chlorophyll c_3 from Emiliania huxleyi

摘要

We report herein the isolation and complete characterization of a member of the chlorophyll c family, designated as [8-ethyl]-chlorophyll c_3 ([8-ethyl]-chl c_3). Structural elucidation of this pigment rested on the analysis of mono- and bidimensional NMR, UV-VIS spectroscopy and ESI-MS data, and the configuration at the 13~2 position on chiral HPLC analysis.
