Abstract

The leaves of Cupressus funebris (Cupressaceae) were shown to contain four chlorophyll-derived pigments (2-5a), together with a new natural norlabdane-type diterpene 1a. Compounds 1a and 5a were isolated as methyl esters 1b and 5b. The pigments were identified as pheophytin a (2), 10S- and 10R-hydroxypheophytin a (3 and 4), and methyl pheophorbide a (5b), from spectroscopic analyses.
