ROMOFF, Paulete et al. Chemical composition of volatile oils from leaves of Nectandra megapotamica Spreng. (Lauraceae). Quím. Nova [online]. 2010, vol.33, n.5, pp. 1119-1121. ISSN 0100-4042. http://dx.doi.org/10.1590/S0100-40422010000500021.
The volatile oils from Nectandra megapotamica Spreng. leaves, collected in February and August of 2007 and at 7:00 and 12:00 h (samples A - D), were extracted by hydrodistillation and the chemical composition was analyzed by GC-FID and GC/MS. A total of nineteen compounds were identified with predominance of oxygenated sesquiterpenes, among them, α-bisabolol, was the main constituent (62.3-69.4 %). After chromatographic separation procedures, this compound was purified from crude oil and its structure was confirmed by analysis of NMR data. This paper describes for the first time the composition of the leaves volatile oil from N. megapotamica.
