The objective of this study was to evaluate the bioactivity of extracts and by-products of volatile oil extraction from rosewood, as well as to quantify linalool levels in hydrolates. Branch and trunkwood methanol extracts presented significant lethality to Artemia franciscana larvae (LC 50 58 ± 33 and 71 ± 31 mg mL -1, respectively). Hydrolates (diluted to 25%) and volatile oil (2 mg mL -1) caused 100% mortality. These results show that A. duckei is a potential source of cytotoxic substances. The volatile oil obtained from branchwood presented larvicidal activity in vitro towards Aedes aegypti (hemorrhagic dengue fever vector, LC 50 2,2 g L -1). Quantitative GC analysis performed on the hydrolate obtained from leaf extraction revealed a linalool concentration of 0.09% v/v (6 mM), which could be responsible for the observed bioactivity. |
