- Floral scent of brazilian Passiflora: five species analised by dynamic headspace DANIEL A. V. MONTERO MARCIA ORTIZ M. MARQUES LAURA M. M. MELETTI MARIA H. VAN KAMPEN SANDRA C. POLOZZI Multidisciplinaria (Ciencias Naturales y Exactas) fragrances Passiflora Chemical composition olfactive description This study describes for the first time the chemical composition and olfactive description of floral scent from Brazilian Passiflora ( Passiflora edulis Sim, Passiflora alata Curtis, Passiflora cincinnata Mast., Passiflora coccinea Aubl. and Passiflora quadrangularis L.). Five species were grown in greenhouse at the Agronomic Institute (IAC), São Paulo, Brazil. Volatile compounds were collected using dynamic headspace. Analyses of scent composition were performed by gas chromatograph coupled to mass spectrometer. Identification of chemical constituents was conducted through of retention index followed by comparative analysis of mass spectra with specialized databases. The olfactive descriptions of floral scent from each species was evaluated for a professional perfumer. High interspecific diversity was found between chemical compositions of floral scent within Passiflora and different bouquets were observed amount the studied species. Mayor constituents were linalool ( P. alata), geraniol ( P. quadrangularis ), 1,4-dimethoxybenzene ( P. edulis ), benzaldehyde ( P. cincinnata ) and 2-methyl-3-pentanone ( P. coccinea ). 2016 artículo científico 0001-3765 https://www.redalyc.org/articulo.oa?id=32746972003 en http://www.redalyc.org/revista.oa?id=327 Anais da Academia Brasileira de Ciências application/pdf Academia Brasileira de Ciências Anais da Academia Brasileira de Ciências (Brasil) Num.3 Vol.88
