Chromenone Glucosides Acylated with Monoterpene Acids from the Leaves of Eucalyptus camaldulensis var. obtusa[Reference: WebLink]

METHODS AND RESULTS:
Three new chromenone glucosides acylated with monoterpene acids, eucamaldusides A (1), B (2), and C (3), were isolated from the leaves of Eucalyptus camaldulensis var. obtusa, together with the five known compounds ursolic acid lactone, Obtusilin, β-sitosterol glucoside, 4-hydroxybenzoic acid, and cypellocarpin C. The structures of the new compounds were established by exhaustive 1D- and 2D-NMR spectroscopic studies.
CONCLUSIONS:
Their configuration was determined by measuring the [α]D of the known methyl esters of the monoterpene acids obtained by methanolysis of 1–3.
