The chemical compositions of essential oils of some Piper species were determined by capillary GC and capillary GCยฑMS. Elemol (11.5%) constituted the most abundant component of Piper nigrum leaf oil, b-Caryophyllene (13%) was the major constituent of P. attenuatum leaf oil, whereas b-cubebene (10%)

โฆ Synopsis
The leaf oil of Dryadodaphne sp. (Mt. Lewis B.P. Hyland RFK1496) contained d-cadinene (10.7%), globulol (4.6%) and T-cadinol (3.7%) as major compounds. In the bark and wood, the major compounds were guaiol and bulnesol, with these compounds being approximately twice as prevalent in the bark as in wood. In Levieria acuminata, the principal component of the leaf oil was n-dodecanal (28%), with d-cadinene (5.8%) and calamenene (5.7%) being the principal sesquiterpenes. Kibara rigidifolia produced a complex leaf oil rich in sesquiterpenes, which also contained (Z)-b-ocimene (3ยฑ12%) and (E)-b-ocimene (1.5%) as principal monoterpenes. The principal sesquiterpenes were bicyclogermacrene, germacrene-B, guaiol and spathulenol.
