Ramos Paredes Santiago Tarqui Ever Gutiérrez Eduardo Oña Yonny Flores Giovanna R. Almanza Química tola Baccharis latifolia densiflora papilllosa The essential oils from the leaves of five species of the genus Baccharis, namely Baccharis boliviensis, B. densiflora, B. latifolia, B. papilllosa and B. tola collected in three counties, Cota-Cota, Mecapaca and Carpani at La Paz, Bolivia, were extracted using hydrodistillation procedures and subsequently analyzed by GC/MS. Four of the species were collected in two places of the La Paz valley, in order to establish the changes in composition in function of the place of origin. B. densiflora was collected only in one place because of the scarcely availability of the plant material in the other collecting sites. The essential oils obtained from the five species are composed mainly by monoterpenes, and a less percentage of sesquiterpenes, in addition, few non terpenic components were detected. The only exception was B. latifolia that showed almost the same amount of sesquiterpenes and monoterpenes. The samples of a same species collected at two different sites showed, as a rule, similar GC/MS profiles with the exception of B. tola that showed higher amounts of hydrocarbon sesquiterpenes and lower quantities of cyclic monoterpenes from Carpani to Cota Cota. The analysis of the identified compounds showed that some of them were present in good quantities in all the samples of essential oils examined, like for instance, β-myrcene, D-limonene, α-thujene, D-α-pinene, sabinene, L-β-pinene and α-muurolene. 2020 artículo científico 0250-5460 https://www.redalyc.org/articulo.oa?id=426363282001 https://www.redalyc.org/journal/4263/426363282001/ https://www.redalyc.org/journal/4263/426363282001/html/ https://www.redalyc.org/journal/4263/426363282001/426363282001.epub https://www.redalyc.org/journal/4263/426363282001/movil en http://www.redalyc.org/revista.oa?id=4263 Revista Boliviana de Química application/pdf Universidad Mayor de San Andrés Revista Boliviana de Química (Estado Plurinacional de Bolivia) Num.1 Vol.37 |
