Abstract
The essential oils obtained from the leaf of Phoebe paniculata (Wall. ex Nees) Nees, as well as the leaf and stem of Phoebe tavoyana (Meissn.) Hook. f. (Lauraceae) were analysed using gas chromatography- flame ionization detector (GC-FID) and gas chromatography coupled with mass spectrometry (GC/MS). The yields of the essential oils were 0.21 % and 0.18 % (v/w) respectively, calculated on dry weight basis. The constituents occurring in higher amounts in the leaf oil of P. paniculata were β-caryophyllene (12.1 %), germacrene D (9.2 %), sabinene (8.8 %) and β-cubebene (7.5 %). On the other hand, bicyclogermacrene (15.5 %), germacrene D (13.9 %), sabinene (7.0 %) and β-caryophyllene (7.0 %) were the main compounds of P. tovayana leaf oil. The stem oil had ar-turmerone (6.8 %), spathulenol (5.6 %) and α-pinene (4.1 %) in significant quantity. The constituents of essential oils from both plants are being reported for the first time.
