Bioactivity and chemical composition of the leaf essential oil of Talauma gloriensis Pittier (Magnoliaceae) from

Abstract: The leaf essential oil of Talauma gloriensis was obtained by hydrodistillation and analyzed by gas chromatography-mass spectrometry (GC-MS). The most abundant essential oil components were myrcene (31.7%) and germacrene D (43.5%). The leaf oil showed notable brine shrimp toxicity (LC50 = 14.1 µg/mL) and slight cruzain inhibitory activity (IC50 = 98.6 µg/mL), but was devoid of cytotoxic activity or antibacterial activity.
