Efforts to evaluate the biodegradation of chlorophyll in autumnal leaves continues. The chlorophyll biodegradation pattern was determined in Hamamelidaceae family. The chlorophyll biodegradation in Vitis vinifera var. Pinot noir autumnal leaves is the same as in the Hamamelidaceae species. The study was performed by LC/MS analysis. The chromatogram obtained for the Vitis vinifera var. Pinot noir autumnal leaf extract was compared with the chromatograms obtained for the Hamamelidaceae species, where the chlorophyll biodegradation pattern was determined. Using LC/MS analysis the chlorophyll biodegradation pattern was validated in Vitis vinifera var. Pinot noir autumnal leaves. The LC/MS analysis of autumnal leaf extracts will allow the identification of chlorophyll biodegradation products among other Vitaceae species.
