Chlorophyll catabolite from Parrotia persica autumnal leaves

Abstract

Biodegradation of chlorophyll is observable biochemical process visualized, in autumn, by the loss of the green leaf colour. A chlorophyll catabolite was isolated from scarlet - red, bright red and yellow Parrotia persica, Hamamelidaceae autumnal leaves. The structure of isolated chlorophyll catabolite was elucidated by UV - Vis - , CD - , HRESIMS - , 1D - and 2D - homonuclear and 2D - heteronuclear NMR - spectra. The full structure of the isolated chlorophyll catabolite was identified as the 31 - hydroxyl - 8 4 - methyl - 81 - oxo - 82, 10 - cyclo urobilinogen.
