Abstract
Two alpha-monomethyl chromene derivatives were isolated from the leaf essen tial oil of Calyptranthes tricona from Brazil which were characterized by H -1- and C-13-NMR. Besides these components, which represent about half of t he oil, classical terpenoid structures could be identified. among which cis -beta-farnesene is the most abundant (26.6%). A biosynthetic pathway could be proposed to explain the formation of the chromene derivatives in the pla nt. (C) 2000 Elsevier Science Ltd. All rights reserved.
