- Volatile chemical composition and bioactivities from Colombian Kyllinga pumila Michx (Cyperaceae) essential oil Beatriz Eugenia Jaramillo-Colorado Eduardo Luis Martínez-Cáceres Edisson Duarte-Restrepo Biología DPPH fumigant phytotoxic Essential oils repellent activity The essential oil from the fresh leaves of Kyllinga pumila (Michx) was obtained by hydrodistillation and characterized by gas chromato graphy-mass spectrometry (GC-MS). Twenty-eight volatile compounds were identified, major constituen ts of the oil were Methyl E,E-10,11-epoxyfarnesoate (43.8%), β -elemene (12.5%), Z-caryophyllene (11.3%), ge rmacrene D (7.1%) and E-caryophyllene (5.6%). Repellent and fumigant activities of the oil against Tribolium castaneum Herbst (Coleoptera: Tenebrionidae), were done using the area preferen ce method. Additionally, we studied their antioxidant and phytotoxic effects. Essential oils exhibited a dose-dependent repellent activity, with values 90% at the applied concentration (0.01%), for both two and four hour’s exposure. Essential oil from K. pumila showed 92% mortality at 500 μ L L -1 air against T. castaneum on 24 hours of exposure. The value LC 50 was 153.4 μ L L -1 . With moderate selective phytotoxic effects on L. perenne root growth (±70% inhibition). Kyllinga pumila shows high antioxidant potential (91.5%), an effect that is comparable with ascorb ic acid (92.9%) used as a standard. The results indicated that K. pumila essential oil could be a promising alternative to new natural antioxidants, repellents, and biocides. 2016 artículo científico 1679-9283 https://www.redalyc.org/articulo.oa?id=187148891003 https://www.redalyc.org/journal/1871/187148891003/ https://www.redalyc.org/journal/1871/187148891003/html/ https://www.redalyc.org/journal/1871/187148891003/187148891003.epub https://www.redalyc.org/journal/1871/187148891003/movil en http://www.redalyc.org/revista.oa?id=1871 Acta Scientiarum.
