摘要：

Essential oils from leaves, steins and roots of Plectranthus barbatus Andr. (Labiatae) were analyzed by GC/MS. The major constituents found were alpha-pinene (22.2%) in the leaves, beta-phellandrene (26.1%) in the steins, and (Z)-beta-ocimene (37.6%) in the roots. Although diterpenes were reported previously in this species, this is the first time that manool (1.0%) and abietatriene (0.7%) have been found in the leaf, and roots oils, respectively.
