Cercidiphyllum

Chlorophyll catabolism has been intensively studied in some plants, e.g., rape-seed, barley, spinach, tobacco, Cercidiphyllum japonicum, Lolium temulentum, Liq-quidambar styraciflua and Arabidopsis thaliana, which present all NCC catabolites with similar basic structures. " This suggests a uniform breakdown of chlorophyll in which the oxidative opening of pheophorbide a seems to be a key step. Structural differences among the compounds have been related to at least six basic types of peripheral transformations. Some of them seem to operate either in sequence or in parallel, depending on the plant species, which caused the appearances of different... [Pg.439]

Despite the difficulties in extracting and identifying colorless catabolic products that are extremely labile and detectable only in trace amounts, several of the mysteries of chlorophyll catabolism have been revealed and about 14 non-fluorescent chlorophyll catabolytes (NCCs) from higher plants, mainly in senescent leaves, have been detected and analyzed structurally. Among them, NCCs from rapeseed (Bms-sica napus) from Liquidambar styraciflua, from Cercidiphyllum japonicum, five NCCs from degreened leaves of spinach Spinacia oleracea) and, more recently, two NCCs from tobacco Nicotiana rusticd) and five NCCs from Arabidopsis thaliana have been identified. [Pg.440]

Cercidiphyllum japonicum is indigenous to China and Japan and has some importance for its lumber and as an ornamental. Little is known of its chemistry three samples were negative for alkaloids. [Pg.45]
