  • Plants of the Myrtaceae family are rich in secondary metabolites, including essential oils, which are attributed with antifungal, antibacterial and antioxidant properties. Mosiera bullata (Britton & P. Wilson) Bisse subsp. bullata is an endemic species of central Cuba, very little studied. The present work aimed to characterize the physical-chemical properties of essential oils from leaves of M. bullata subsp. bullata. Fresh leaves of this species were collected from the serpentine soil of Camagüey province, Cuba. To establish the methodology for extracting essential oils, the hydrodistillation method was used and the following parameters were evaluated: extraction time, mass-volume ratio and yield. For the physical-chemical characterization, the following parameters were determined: relative density, refraction index at 20ºC, acidity index and solubility in ethanol 70, 90, 95 and 97 % (v/v). The highest extraction yield (1.57 ± 0.0003 % (v: w, based on fresh plant weight) was obtained with the 1:5 (w: v) ratio for 3 h of extraction. The essential oils of this species obtained under these conditions presented the following characteristics: 0.8708 ± 0.0006 g mL-1 relative density, 1.4567 ± 0.0014 refractive index at 20ºC, 4.21 ± 0.4661 mg KOH/g acidity index, soluble in ethanol 90, 95 and 97 % and slightly soluble in ethanol 70 %. These last two physical-chemical properties were described for the first time for the essential oils of this species. The essential oils of M. bullata subsp. bullata showed characteristics that are within the range of those described for essential oils of other species of the family Myrtaceae. Further studies are required to evaluate its potential in areas such as the cosmetic, pharmaceutical, agricultural and food industries.
