Description
Summary:	The hydro-distillation essential oil was obtained from the leaf, stem, and flower of (Willd.) M.R.Almeida (Asteraceae) and analysed using gas chromatography equipped with a flame ionisation detector (GC-FID) and gas chromatography coupled with mass spectrometry (GC-MS). Fifty-eight, sixty-nine and, fifty-seven constituents were identified from leaf oil (LO), stem oil (SO) and flower oil (FO), representing 95.8%, 96.3% and 95.1% of the total oil constituents, respectively. The major constituents were identified as germacrene D (39.6-48.1%), humulene (4.9-8.9%), -caryophyllene (4.8-7.7%), and -cadinol (2.9-6.8%) from different parts of the plant . The oils were found to be rich in sesquiterpenoid-type constituents.
