Use of palmae wax hydrocarbon fractions as chemotaxonomical markers in Butia and Syagrus

Abstract: The wax hydrocarbon fractions of native Butia and Syagrus species collected from Palms in different regions of the of Rio Grande do Sul state (Brazil) and in Rocha (Uruguay) were analyzed to evaluate their potential as chemotaxonomic markers. The wax was extracted with chloroform and the resulting wax was fractionated by preparative TLC. The hydrocarbon fractions were analyzed by GC-MS. Statistical analyses were completed with the Statistica 5.0 program. The total crude wax yields averaged 0.31% w.w -1 dried l… Show more

“…Because of the family size as well as the similarity of many wild species within a single genus, the taxonomy of Solanaceae is difficult and morphological traits are not always sufficient markers in plant classification. Among other markers, leaf cuticular wax composition (usually hydrocarbon profile) is often used in chemotaxonomic studies of many plant families [3][4][5][6][7][8][9]. Leaf waxes are easily extracted and analyzed, and at least some of their fractions display a stable composition within a single species during plant growth and development.…”

“…In case of chemotaxonomic analysis based on the hydrocarbon profile, the most popular method is column chromatography (CC) with alumina [10] or silica gel [3-6, 11, 13]. Preparative thin-layer chromatography (TLC) also offers sufficient separation of cuticular wax components [9,12]. Both methods, however, are timeconsuming, and they also require the use of relatively large volumes of organic solvents, particularly in column chromatography.…”

“…Os lipídeos das ceras são moléculas bastante estáveis e resistentes à degradação ao longo do tempo (Eglinton et al, 1991). Deste modo, muitas vezes são usadas em estudos quimiotaxonômicos, principalmente os alcanos (Salatino et al, 1989;Mimura et al, 1998;Skorupa et al, 1998;Santos et al, 2005;Rocini et al, 2005;Medina et al, 2006;Motta et al, 2008;Paroul et al, 2009;Bush & McInerney, 2013). Neste estudo foi visto que a composição das ceras não foi capaz de trazer uma contribuição a taxonomia de Simaba s.s. e Homalolepis, assim como visto para Camerea (Malpighiaceae) (Motta et al, 2008).…”
