Essential Oil ofGaillardia megapotamica(Spreng.) Backer var.radiata(Gris.) Backer from San Luis, Argentina

Rapid Analysis of the Volatile Components of Gaillardia aristata and G. × grandiflora

“…The principal difference between the compositions of the two species of Gaillardia is related to limonene: a higher content of it was detected in the Burgunder species. From a qualitative point of view, our results are comparable with those already reported in the literature [8,9], while the quantitative analysis is quite different. For instance, a study of the volatile components of Gaillardia aristata [2] has shown that the main components were J-muurolene (16.69%), (E)-caryophyllene (9.73%), and E-pinene (9.70%).…”

Evaluation of Chemical and Antiviral Properties of Essential Oils from South American Plants

“…Injection volume was 0.1 µl, (split 1:80). The identification of oil components was based on comparison of their mass spectra with those found in the literature (Duschatzky et al, 2003), MS data bank (NIST) and a computer search of the Wiley library (McLafferty & Stauffer, 1994). The retention index was determined by coinjection of the homologous N-hydrocarbon C 8 -C 18 mixture with the oil sample.…”
