Characterization of Volatile Compounds of Eleven Achillea Species from Turkey and Biological Activities of Essential Oil and Methanol Extract of A. hamzaoglui Arabacı & Budak

Lippia sidoides Cham. is a plant that belongs to the family Verbenaceae and is commonly known as “alecrim-pimenta”. It was first found in northeastern Brazil, where it is extensively used in traditional medicine. Many studies have been made with the essential oil of L. sidoides, which has a high content of the isomeric compounds thymol and carvacrol. L. sidoides extracts, and particularly the essential oil extracted from its aerial parts, have shown many biological activities such as antifungal, antibacterial, and insecticidal. Given the great biological potentialities of L. sidoides and the amount of recent studies about this plant, the present study aimed to make a survey of its general attributes, cultivation methods, chemical characterization of its extracts and essential oil, as well as its different biological activities.

This study is a pioneer in reporting the antibacterial properties of the species Croton ceanothifolius Baill. The genus Croton belongs to the family Euphorbiaceae composed of numerous species with documented biological activities. However, the pharmacological properties of C. ceanothifolius remain poorly understood. The leaves of this plant were submitted to hydrodistillation for essential oil (CcEO) extraction and the phytochemical characterization of the oil was performed by GC/MS. The minimum inhibitory concentration of the CcEO was determined for the evaluation of antibacterial activity against multiresistant strains of Staphylococcus aureus, Pseudomonas aeruginosa, and Escherichia coli. The antibiotic-modulating activity of the oil, in combination with antibiotics, was also evaluated. The combination of the CcEO with penicillin, norfloxacin, and gentamicin presented a synergistic effect. This effect was more significant for the association with antibiotics of the quinolone and aminoglycoside classes against Escherichia coli. The association of oil with gentamicin showed better results with regard to the Gram-positive strain. The association of the oil with norfloxacin against P. aeruginosa also showed synergism, but the association with penicillin did not change the effect of this antibiotic. Thus, it is concluded that C. ceanothifolius essential oil selectively potentiates the action of antibiotics against multiresistant strains.

Clove Essential Oil

Clove (Syzygium aromaticum L. Myrtaceae) is an aromatic plant widely cultivated in tropical and subtropical countries, rich in volatile compounds and antioxidants such as eugenol, β-caryophyllene, and α-humulene. Clove essential oil has received considerable interest due to its wide application in the perfume, cosmetic, health, medical, flavoring, and food industries. Clove essential oil has biological activity relevant to human health, including antimicrobial, antioxidant, and insecticidal activity. The impacts of the extraction method (hydrodistillation, steam distillation, ultrasound-assisted extraction, microwave-assisted extraction, cold pressing, and supercritical fluid extraction) on the concentration of the main volatile compounds in clove essential oil and organic clove extracts are shown. Eugenol is the major compound, accounting for at least 50%. The remaining 10–40% consists of eugenyl acetate, β-caryophyllene, and α-humulene. The main biological activities reported are summarized. Furthermore, the main applications in clove essential oil in the food industry are presented. This review presents new biological applications beneficial for human health, such as anti-inflammatory, analgesic, anesthetic, antinociceptive, and anticancer activity. This review aims to describe the effects of different methods of extracting clove essential oil on its chemical composition and food applications and the biological activities of interest to human health.

New Research

Survey have proven the popular Canellaceae family use to treat various diseases such as: muscular pains, infections, stomatitis, anti-malaric, healing, among others. The main use of these species is in the extracts form and essential oils extracted from the leaves and stem. Highlighting the importance of this family on the pharmacological point of view and the fact that few studies in the literature have reported the characterization of the essential oils compounds and their respective biological activities. The objective of this study was to carry out a systematic review of previous studies on essential oils of the Canellaceae family species and their biological activities. The databases Scopus, Web of Science and PubMed were used for the search and a bibliographical manager was used. A total of 143 files were analyzed, of which 21 presented the phytochemical analysis and / or essential oils biological activities of these species. Few species have been studied so far, such as Canella winterana, Cinnamosma fragans, Cinnamosma madagascariensis, Cinnamodendron dinisii. It can be observed that the major constituents for these species essential oils were: 1,8-cineol, linalool, limonene, alpha and beta-pinene. And that the main proven activities were: antibiotic, antifungal, insecticide, larvicide, trypanocidal, cytotoxic, molluscicide, immunomodulatory, anti-inflammatory and anticonvulcionate. From this literature review, it was possible to identify species that have not yet started studies and possible activities of their essential oils, mainly due to the almost homogeneous presence of the major constituents, making possible new research as well as projects and programs.

Syzygium aromaticum has a diversity of biological activities due to the chemical compounds found in its plant products such as total phenolic compounds and flavonoids. The present work describes the chemical analysis and antimicrobial, antioxidant, and antitrypanosomal activity of the essential oil of S. aromaticum. Eugenol (53.23%) as the major compound was verified by gas chromatography-mass spectrometry. S. aromaticum essential oil was more effective against S. aureus (MIC 50 μg/mL) than eugenol (MIC 250 μg/mL). Eugenol presented higher antioxidant activity than S. aromaticum essential oil, with an EC50 of 12.66 and 78.98 µg/mL, respectively. S. aromaticum essential oil and eugenol exhibited Trypanosoma cruzi inhibitory activity, with IC50 of 28.68 ± 1.073 and 31.97 ± 1.061 μg/mL against epimastigotes and IC50 of 64.51 ± 1.658 and 45.73 ± 1.252 μg/mL against intracellular amastigotes, respectively. Both compounds presented low cytotoxicity, with S. aromaticum essential oil displaying 15.5-fold greater selectivity for the parasite than the cells. Nitrite levels in T. cruzi-stimulated cells were reduced by essential oil (47.01%; p = 0.002) and eugenol (48.05%; p = 0.003) treatment. The trypanocidal activity of S. aromaticum essential oil showed that it is reasonable to use it in future research in the search for new therapeutic alternatives for trypanosomiasis.
