Psidium guineense Swartz is a shrub used in urinary tract diseases, diarrhea, and dysentery. The aims of this study were to analyze the seasonal chem. variability of the volatile oils of P. guineense leaves for 12 mo, to evaluate the antimicrobial activity against bacteria and fungus, and the larvicidal activity against third-instar Aedes aegypti larvae. The identification of the volatile oil components was performed by gas chromatog. coupled with mass spectrometry (GC-MS). The antimicrobial and larvicidal activities were assessed by in vitro methodologies. The majority compounds of the volatile oil were (2Z,6E)-farnesol (15.1-51.2%), ¦Á-copaene (5.9-24.6%) and muurola-4,10(14)-dien-1¦Â-ol (2.7-9.6%). The composition varied according to rainfall occurrence: Cluster I (volatile oils from leaves collected in Apr., June, July, August, Sept., Oct., and Dec.- low precipitation months), Cluster II (volatile oils from leaves collected in Jan., Feb., March, May, and Nov. – higher precipitation levels). Cluster I and Cluster II showed strong to moderate activity against Cryptococcus neoformans (MIC = 32-64¦Ìg/mL) and Micrococcus luteus (MIC = 16-32¦Ìg/mL) while promising larvicidal activity was observed against Ae. aegypti (LC50 20.5-36.4¦Ìg/mL; LC90 47.5-70.1¦Ìg/mL). This is the first report describing the seasonal variability of P. guineense volatile oils, antifungal activity against yeasts, and larvicidal activity over Ae. aegypti.
