Abstract
Drimys brasiliensis Miers is a native plant species to the Atlantic Forest, commonly known as cataia, and used as a stimulant, anti-diahrreal, antipyretic, among other properties. Dried and fresh leaves of cataia were collected in autumn/2012, submitted to hydrodistillation in a Clevenger graduated apparatus over a period of 4 hours after reaching the boiling point, then essential oil was collected. In oil from green leaves, 49 compounds were identified, being 65.0% sesquiterpenes, 12.0% monoterpenes and 23.0% other substances. In oil from dry leaves, 40 compounds were identified, being 76.1% sesquiterpenes, 2.0% monoterpenes and 21.9% other compounds. The main constituents in green leaves were germacrene D (8.9%), bicyclegermacrene (5.3%), epi-alpha-cadinol (5.1%), alpha-cadinol (6.0%), and drimenol (9.3%). In dry leaves the main constituents were germacrene D (6.3%), (E)-nerodidol (5.4%), spathulenol (9.5%), epi-alpha-cadinol (5.5%), alpha-cadinol (6.7%), and drimenol (11.6%) Due to its composition, antibacterial, antimycotic, insectifuge and molluscicide activities are proven, together with the pharmacological properties that this species may present.
Highlights
Known as “cataia”, Drimys brasiliensis is a species native that can be used for stimulant to the popular medicine because of the oil composition
There are several studies on the essential oil chemical composition of Drimys brasiliensis bark; according to Radomski et al (2013), there is some difficulty in this study because it is not possible to collect on a large scale or at different times of the year in the same plant as the depletion of the bark on the stem of the same would result in impairment of the phloem sap flow, which the long-term, culminating with the death of the plant
Leaves of 5 years old Drimys brasiliensis Miers, commonly known as “cataia”, Winteraceae family, plants were used for the essential oil extraction
Summary
Known as “cataia”, Drimys brasiliensis is a species native that can be used for stimulant to the popular medicine because of the oil composition. According to Gomes et al (2013), the chemical study of the essential oil Drimys brasiliensis allows to know their biological activities and evaluate their toxicity, to find out more about its therapeutic potential and its possible adverse effects, increasing safety its use by the population.
