OLIVEIRA, J.D. et al. Content, chemical composition and antimicrobial and antioxidant activities of the essential oil from leaves of Campomanesia adamantium submitted to different drying methods. Rev. bras. plantas med. [online]. 2016, vol.18, n.2, pp.502-510. ISSN 1516-0572.  http://dx.doi.org/10.1590/1983-084X/15_206.

C. adamantiumis widely used in popular medicine for thetreatment of hypertension, rheumatism and diabetes. This study looked to evaluate the essential oil yield, the chemical composition and the antimicrobial and antioxidant activities of the essential oil from leaves of C. adamantium. A completely randomized design was used with eight treatments and three replications. The essential oil obtained by hydrodestillation of the leaves was analyzed by GC-MS. The results show that the drying type and the processing of the leaf influence the content and chemical composition of the essential oil. The compounds spathulenol, caryophyllene oxide and germacrene-B have higher concentrationsin mostorigins. The essentialoil from theleaves of C.adamantiumshowed moderate bacterial activityagainst all tested microorganisms. The antioxidant activity was determined by the methods of reduction of the DPPH stable radical. The antioxidant activity was weak in the test used.
