Chlorophyll Catabolite from Parrotia Persica Autumnal Leaves

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 – 84 – methyl – 81 – oxo – 82, 10 – cyclo urobilinogen.
