Abstract
. Analysis of essential oil from fresh leaves of Capraria biflora allowed identification of fourteen essential oil constituents among which thirteen are sesquiterpene compounds, and {alpha}-humulene (43.0%) the major constituent. The essential oil was tested for larvicidal activity against Aedes aegypyti showing good activity, with LC{sub 50} 73.39 {mu}g/mL (2.27 g/mL). Chromatographic studies of extracts from roots and stems allowed the isolation of five compounds: naphthoquinone biflorin, sesquiterpene caprariolide B, the steroid {beta}-sitosterol, the carbohydrate D-mannitol and iridoid myopochlorin first reported in the species C. biflora. The structures of compounds were characterized by spectroscopic data, IR, MS, NMR{sup 13}C, NMR{sup 1}H, NOE, HSQC and HMBC. (author)
