Abstract.Chlorophyll catabolism in Prunus serrulata autumnal leaves was investigated. The amount of chlorophyll catabolites accumulated within the same plant species varies with the time of the leaf collection, seasonal climate and developmental stage of the plant. The chlorophyll catabolites found in P. serrulata autumnal leaves presented the tendency of the organism to decrease the level of photodynamically active chlorophyll before the programmed cell death. In the methanol extract several chlorophyll catabolites were identified. The results obtained by liquid – chromatography/mass spectrometry permitted the identification of the chlorophyll catabolites found in P. serrulata autumnal leaves. The analysis done revealed the chlorophyll catabolic pathway found in P. serrulata autumnal leaves.
Key words: chlorophyll catabolism, Prunus serrulata
KATABOLIZAM HLOROFILA KOD
Prunus serrulata JESENJEG LIŠĆA
Ispitivan je katabolizam hlorofila jesenjeg lišća biljne vrste Prunus serrulata. Količina katabolita hlorofila u jesenjem lišću, koji zapravo predstavljaju tendenciju organizma da smanji nivo fotodinamički aktivnog hlorofila pre programirane smrti ćelije, zavisi od vremena sakupljanja lišća, klime i razvojnog doba biljke. Analizom hemijskog sastava metanolnog ekstrakta jesenjeg lišća vrste P. serrulata metodom tečne hromatografije / masene spektrometrije identifikovano je nekoliko katabolita hlorofila. Na osnovu dobijenih rezultata predložen je katabolizam hlorofila koji se odvija u jesenjem lišću vrste P. serrulata.
