Composition and chiral characterization of the essential oil ofBuddleja tucumanensis from Bolivia

Abstract

Analysis by GC and GC-MS of the essential oil obtained from aerial parts of Buddleja tucumanensis revealed 28 components (81% of the total composition). The major constituents were found to be α α α α α-thujene, β β β β β-pinene, α α α α α-pinene, p-cymene, α α α α α-trans-bergamotene and β β β β β-caryophyllene; the enantiomeric distribution of α α α α α-pinene, sabinene, β β β β β-pinene, limonene and terpinen-4-ol was studied by multidimensional HRGC-HRGC. The enantiomeric excess found for each monoterpene allowed better characterization of this species.

“…The components of the oil were analyzed as previously reported [14]; identified by comparison of their Linear Retention Indices (LRIs) on two columns, determined in relation to a homologous series of n-alkanes (C 9 to C 26 ), with those from pure standards or reported in the literature [15,16]. Comparison of fragmentation patterns in the mass spectra with those stored on the GC-MS database was also performed [17,18].…”

“…Comparison of fragmentation patterns in the mass spectra with those stored on the GC-MS database was also performed [17,18]. Enantiomeric ratios of -pinene, -pinene, and limonene were obtained by multidimensional GC using the experimental conditions previously described [14].…”
