Abstract

The dried stems of Arbutus unedo have been investigated for secondary metabolites. In addition to the previously reported lupeol, ursolic acid, monotropein, unedoside, and stilbericoside, the iridoids geniposide (2) and monotropein methyl ester (1) have been isolated for the first time from this source. Betulinic acid (4) has also been isolated for the first time from this plant.
