Eucalyptus cinerea, known as silver dollar tree, has few descriptions in traditional medicine. Chemical composition and antimicrobial properties of the essential oils of leaves, flowers and fruits, collected seasonally, were determined by GC/MS and disk diffusion/MIC, respectively. 1,8-Cineole was the main compound, particularly in fresh leaves—Spring (74.98%), dried leaves—Spring (85.32%), flowers—Winter (78.76%) and fruits—Winter (80.97%). Other compounds were found in the aerial parts in all seasons: α-pinene (2.41% to 10.13%), limonene (1.46% to 4.43%), α-terpineol (1.73% to 11.72%), and α-terpinyl acetate (3.04% to 20.44%). The essential oils showed antimicrobial activities against bacteria and yeasts, with the best results being found for the dried autumn and winter leaves oils (MIC < 0.39 mg/mL) against Streptococcus pyogenes. For the other tested microorganisms the following MIC results were found: Staphylococcus aureus—Dried leaves oil from summer (0.78 mg/mL), Pseudomonas aeruginosa—Flowers oil from autumn and fruits oil from winter (1.56 mg/mL) and Candida albicans—Flowers oil from autumn and fruits oils from winter and spring (0.78 mg/mL).
Eucalyptus cinerea F. Muell. ex Benth. is one of the numerous species of the genus and its main use is ornamental, with few reports of it being used in popular medicine . However, among species of Eucalyptus the yield of essential oil from the leaves of E. cinerea and that of its main compound 1,8-cineole (eucalyptol) are considered high [14-16]. The high concentrations of essential oil in the leaves, as well as in the flowers and fruits, could potentially be employed for therapeutic ends and as natural additives for use in the food, cosmetics and perfume industries, extending the use of the plant beyond the predominantly ornamental.
Reports describing the antimicrobial properties of E. cinerea are scarce; moreover, the antibacterial and antifungal activities of essential oils of its fruits and flowers have not been studied previously. In this context, the objective of the present study was to define the chemical composition of samples of essential oils from the aerial parts—Leaves, flowers and fruits—of E. cinerea collected seasonally, as well as to test the antimicrobial activity of its aromatic oils against Gram-positive (Staphylococcus aureus and Streptococcus pyogenes) and Gram-negative (Pseudomonas aeruginosa and Escherichia coli) bacteria and yeast (Candida albicans).
Eucalyptol (1,8-cineole) is the major chemical component of the oils obtained from leaves for the majority of medicinal species of Eucalyptus, such as E. staigeriana , E. globulus [11,21], and E. urophylla . Nevertheless, the main component in other species of Eucalyptus may be a different compound, such as piperitone—E. dives; (E)-methyl cinnamate—E. olida , α-pinene—E. camaldulensis , limonene—E. staigeriana , β-citronellal—E. citriodora , and p-cymene—Eucalyptus tereticorni .
The main volatile compound identified in all of the aerial parts of E. cinerea collected seasonally was 1,8-cineole, which reached a concentration of 85.32%. In addition to this compound, others that were found included α-pinene, limonene, α-terpineol, and α-terpinyl acetate.
