1,8-Cineole Chemotype of the Essential Oils of Kyllinga erecta Schum et Thonn and its Antimicrobial Activities

The investigation of the essential oils of the aerial part and rhizomes of Kyllinga erecta by capillary gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS) led to the identification of 31 and 49 compounds respectively. The oil of the aerial parts had 1,8-cineole (10.5%), α-humulene (21.7%), farnesyl acetate (11.2%), β-caryophyllene (9.9%) and selin-11-en-4-ol (8.9%) as the major components, while the rhizome oil was dominated by 1,8-cineole (12.7%) and cyperene (11.34%) and E,E-farnesol (5.5%). This analyses, especially that of the rhizome oil, suggest another chemotype of K. erecta from the known predominant cyperene-type.
