摘要：

A group of novel non-green catabolites of chlorophyll is presented. The native compounds are colourless but on thin layer silicagel plates they are readily oxidized to rust-coloured pigments (RPs). In senescent primary leaves of barley the predominant RP, RP 14, is progressively accumulated. It is located in the vacuoles of senescent mesophyll cells. The origin of RP 14 from chlorophyll has been demonstrated by means of radiolabelling of porphyrins during the greening of etiolated barley seedlings and tracing of the label during subsequent induction of senescence. RI's appear to represent secondary or even final products of chlorophyll breakdown. © 1990, Gustav Fischer Verlag, Stuttgart. All rights reserved.
