Evaluation of climatic factors on the yield and chemical composition of the essential oil ofMyrocarpus frondosus

Abstract

The species Myrocarpus frondosus is native to southern Brazil, and it is known as cabreúva. It is a large tree, and its wood is used as a reservoir for distilled spirits, especially Cachaça. In this pioneering work, the essential oil was extracted monthly from the leaves of M. frondosus, for a period of 1 year. The essential oil was extracted by using hydrodistillation and the determination of the chemical composition of essential oil was performed by using the chromatographic techniques GC-FID and GC-MS. Thirty-three compounds were identified in the essential oil and bicyclogermacrene was the major compound. Through multivariate analysis, it was determined that β-caryophyllene, limonene and terpinen-4-ol were directly proportional to climatic factors. The yield of the oil was directly proportional to temperature and radiation.

Antifungal Activity of the Essential Oils of Osteophloeum platyspermum (Myristicaceae) against Malassezia spp. and Candida albicans Influenced by Seasonality and Climatic Factors

“…The yields of the essential oils obtained in the RS were significantly higher than those produced during the DS, possibly due to the higher water availability during RS, which may favor a greater volume of EO for this species. A similar observation was made in a study performed with the EO obtained from the leaves of Myrocarpus frondosus, a tree occurring in Southern Brazil [43], where the authors identified a higher oil yield during the winter. On the other hand, in a similar study carried out with Lippia origanoides (Verbenaceae), an herbaceous plant that grows in several Brazilian ecosystems, including the Amazon forest, the mean yields of the EOs collected in the DS was not statistically different from the mean yields of the EOs from the plant collected in the RS [44].…”

Behavioural responses of Vespula germanica (Hymenoptera: Vespidae) wasps exposed to essential oils

“…Limonene, terpinen-4-ol, b-caryophyllene, spathulenol and globulol have been found present throughout the year in incense essential oil (Cabrera et al 2015). In the case of lemongrass, geranial (citral-a), neral (citral-b) and myrcene are the main components (Hanaa et al 2012).…”

Potencial econômico e terapêutico dos óleos essenciais mais utilizados no Brasil

“…O óleo essencial extraído de suas folhas teve uma exportação de 438 quilogramas, na qual se observa uma variância muito grande de quantidade exportada pelo período de tempo estudado [39] . Em importação obteve-se 39 toneladas do Apenas um estudo foi encontrado sobre o óleo essencial de cabreúva, no qual se buscou a relação e a influência dos fatores climáticos na composição química do mesmo [43] .…”
