GRAPHICAL ABSTRACT

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 (LC 50 = 14.1 µg/mL) and slight cruzain inhibitory activity (IC 50 = 98.6 µg/mL), but was devoid of cytotoxic activity or antibacterial activity.
