“…When comparing the antibacterial activity of the C. concinna essential oil with other plants from the same genus, Calyptranthes pallens demonstrated an antibacterial effect against S. aureus with a MIC of 39 µg/mL, obtaining similar results against P. aeruginosa (MIC = 625 µg/mL) [27]. However, studies with Calyptranthes microphylla did not demonstrate any antibacterial effect against the same bacteria using the disk diffusion method [28].…”

Presently, results from a study carried out in this area using the essential oil from the Calyptranthes concinna species, a representative from the Myrtaceae family, are reported. The essential oil was obtained by hydrodistillation and gas chromatography coupled to mass spectrometry was used to identify its chemical constituents. Antibacterial activity was determined using the broth microdilution method, thus obtaining the Minimal Inhibitory Concentration (MIC) value, from which the subinhibitory concentration (MIC/8) was derived. The C. concinna essential oil presented antibacterial activity against both standard and multiresistant bacteria. In addition, the oil demonstrated an antibiotic activity potentiation against Staphylococcus aureus and Escherichia coli when in combination with the antibiotic gentamicin, reducing the MIC from 141.38 μg/mL and 208.63 μg/mL to 64 μg/mL and 128 μg/mL, respectively. Conclusions: Findings from the present study suggest this oil is promising in terms of its antimicrobial activity.

“…The American genus Calyptranthes comprises about 100 species distributed from Mexico to Uruguay. Most of the phytochemical studies about this genus have been on the chemical composition of the essential oils [13][14][15][16][17][18][19][20][21]. Calyptranthes restingae Sobral, known as "murta", is a rare species of the northeastern Brazilian rainforests.…”

Calyptranthes restingae Sobral, known as "murta", is a species of the northeastern Brazilian used to treat fever, pain and inflammatory disorders. The essential oil from Calyptranthes restingae Sobral (Myrtaceae) collected in Sergipe, northeastern Brazil, was obtained through the hydrodistillation and its antinociceptive properties were evaluated. Chromatographic analysis revealed 14 components, but only five were identified, accounting for 98.50% of the oil: (E)-caryophyllene (2.40%), calyptrantone (81.03%), α-humulene (1.52%), β-selinene (8.54%), α-selinene (5.01%). The structure of the major compound, calyptrantone, was elucidated by 1 H and 13 C-NMR. This is the first time that a β-triketone has been identified in the essential oil of Calyptranthes genus and that calyptrantone has been reported as a natural product. This essential oil showed an antinociceptive effect in mice, reducing acetic-acidinduced abdominal writhing significantly in comparison with the control group (p<0.001), with the possible participation of opioids. In the formalin test, the oil also caused significant inhibition of licking time in both phases without loss of motor coordination. Besides, all doses of the oil decreased the leukocyte migration in peritoneal cavity induced by carrageenan (p<0.01). Together, these results indicate that the essential oil of C. restingae represents an important potential tool for management of neurogenic and inflammatory pain.
