Abstract:	Chlorophyll catabolism was induced in two Hamamelidaceae plant species by placing detached leaves in darkness. The induced chlorophyll catabolism was observed by visible leaves’ yellowing. The extracts of the yellowed leaves were analyzed by liquid chromatography-mass spectrometry. On the basis of the chlorophyll catabolites registered in the chromatograms, summarized were the results which permitted the proposition of the chlorophyll catabolic pathway in two Hamamelidaceae plant species under dark-induced senescence. The time interval for the induction of chlorophyll catabolism, in two Hamamelidaceae plant species, differed significantly.
