Reinvestigation of carvotanacetone after 100 years along with minor terpenoid constituents of Blumea malcolmii Hook. F. essential oil.
Reinvestigation of essential oil constituents of Blumea malcolmii Hook. F. (Asteraceae) was carried out after 100 years using gas chromatography equipped with flame ionisation detector (GC-FID) and gas chromatography coupled with mass spectrometry (GC/MS). Eighteen constituents, representing 99.2% of the total oil, were identified. The major compound was identified by GC/MS and NMR ((1)H and (13)C) as carvotanacetone (92.1%). The minor compounds of essential oil have also been identified for the first time in B. malcolmii. The oil was found to be rich in oxygenated monoterpene-type constituents (95.0%).
