CHEMICAL CONTENTS
The plant contains plenty of sesquiterpene derivatives: ß-elemene, isocaryophyllene, ß-caryophyllene, ahumulene, ?-muurolene, OC-selinene, a -muurolene, germacrene A, ß-cadinene and the alcohols: elemol, (E)-nerolidol, spathulenol, globulol, epi-globulol, 1-epi-cubenol, d-epi-cadinol, á -epi-muurolol, and á -cadinol.
The cadinols, cadinenes and caryophyllenes predominated in both oils. The difference observed in the compositions of the two oil samples concerned the caryophyllenes. isocaryophyllene was more abundant than the ß-isomer at 6 a.m., while at 9 a.m. the relative proportions were reversed. 6-cadinene was more abundant at 9 a.m. (9.1% versus 4.5% at 6 a.m.). Analogous variations were observed for tx-epi-cadinol (8.4% versus 4.1%).
