Chemical composition and antibacterial activity of essential oils from Citrus aurantifolia leaves and fruit peel against oral pathogenic bacteria Anais da ABC (AABC)
LEMES,RAIANE S.; ALVES,CASSIA C.F.; ESTEVAM,ELISÂNGELA B.B.; SANTIAGO,MARIANA B.; MARTINS,CARLOS H.G.; SANTOS,TAINÁ C.L. DOS; CROTTI,ANTÔNIO E.M.; MIRANDA,MAYKER L.D..
ABSTRACT Tooth decay is a major public health problem which affects a large number of people in several countries. Even though more than 700 bacterial species have been detected in the oral cavity, Streptococcus and Lactobacillus stand out as the genera that cause tooth decay and other periodontal diseases. In this study, essential oils from Citrus aurantifolia leaves (CL-EO) and fruit peel (CP-EO) were obtained by hydrodistillation by a Clevenger-type apparatus whereas their chemical composition was analyzed by gas chromatography-flame ionization detector (GC-FID) and gas chromatography-mass spectrometry (GC-MS). Limonene (77.5 %), linalool (20.1 %), citronellal (14.5 %) and citronellol (14.2 %) were the main constituents found in the essential oils from...

In vitro antiparasitic activity and chemical composition of the essential oil from Protium ovatum leaves (Burceraceae) Anais da ABC (AABC)
ESTEVAM,ELISÂNGELA B.B.; DEUS,ISABELLA P.B. DE; SILVA,VANESSA P. DA; SILVA,ELIZABETH A.J. DA; ALVES,CASSIA C.F.; ALVES,JOSÉ MILTON; CAZAL,CRISTIANE M.; MAGALHÃES,LIZANDRA G.; PAGOTTI,MARIANA C.; ESPERANDIM,VIVIANE R.; SOUZA,ALEX F.; MIRANDA,MAYKER L.D..
ABSTRACT Leishmaniasis and trypanosomiasis are globally widespread parasitic diseases which have been responsible for high mortality rates. Since drugs available for their treatment are highly hepatotoxic, nephrotoxic and cardiotoxic, adherence to therapy has been affected. Thus, the search for new, more effective and safer drugs for the treatment of these diseases is necessary. Natural products have stood out as an alternative to searching for new bioactive molecules with therapeutic potential. In this study, the chemical composition and antiparasitic activity of the essential oil from Protium ovatum leaves against trypomastigote forms of Trypanosoma cruzi and the promastigote forms of Leishmania amazonensis were evaluated. The essential oil was promising...

Essential oils from Piper aduncum inflorescences and leaves: chemical composition and antifungal activity against Sclerotinia sclerotiorum Anais da ABC (AABC)
VALADARES,ANNA CAROLINA F.; ALVES,CASSIA CRISTINA F.; ALVES,JOSÉ MILTON; DE DEUS,ISABELLA P.B.; DE OLIVEIRA FILHO,JOSEMAR G.; DOS SANTOS,TAINÁ CAROLINE L.; DIAS,HERBERT JÚNIOR; CROTTI,ANTÔNIO EDUARDO M.; MIRANDA,MAYKER L.D..
Abstract Even though essential oils from Piper aduncum (Piperaceae) have different biological activities, little is known about their application to agricultural areas. White mold is a plant disease caused by the phytopathogen Sclerotinia sclerotiorum, which needs to be controlled by alternative measures. This study aimed at evaluating the effect of essential oils from P. aduncum leaves (PL-EO) and inflorescences (PI-EO) on the mycelial growth of S. sclerotiorum. Essential oils from P. aduncum were obtained by hydrodistillation by a Clevenger-type apparatus while their chemical composition was analyzed by GC-MS and GC-FID. Piperitone (23.4 %), myristicin (12.4 %), terpinen-4-ol (12.3 %), β-caryophyllene (7.2 %), α-humulene (6.9 %), germacrene-D (6.9 %) and...

Chemical composition, antioxidant and antibacterial activities of essential oils from leaves and flowers of Eugenia klotzschiana Berg (Myrtaceae) Anais da ABC (AABC)
CARNEIRO,NÁRGELLA S.; ALVES,CASSIA C.F.; ALVES,JOSÉ M.; EGEA,MARIANA B.; MARTINS,CARLOS H.G.; SILVA,THAYNÁ S.; BRETANHA,LIZANDRA C.; BALLESTE,MAIRA P.; MICKE,GUSTAVO A.; SILVEIRA,EDUARDO V.; MIRANDA,MAYKER L.D..
ABSTRACT Many essential oils (EOs) of different plant species possess interesting antimicrobial effects on buccal bacteria and antioxidant properties. Eugenia klotzschiana Berg (pêra-do-cerrado, in Portuguese) is a species of Myrtaceae with restricted distribution in the Cerrado. The essential oils were extracted through the hydrodistillation technique using a modified Clevenger apparatus (2 hours) and chemically characterized by GC-MS. The major compounds were α-copaene (10.6 %) found in oil from leaves in natura, β-bisabolene (17.4 %) in the essential oil from dry leaves and α-(E)-bergamotene (29.9 %) in oil from flowers. The antioxidant activity of essential oils showed similarities in both methods under analysis (DPPH and ABTS˙+) and the results...

Chemical composition and evaluation of antileishmanial and cytotoxic activities of the essential oil from leaves of Cryptocarya aschersoniana Mez. (Lauraceae Juss.) Anais da ABC (AABC)
ANDRADE,PRISCILA M. DE; MELO,DAIANA C. DE; ALCOBA,ANA ELISA T.; FERREIRA JÚNIOR,WALNIR G.; PAGOTTI,MARIANA C.; MAGALHÃES,LIZANDRA G.; SANTOS,TAINÁ C.L. DOS; CROTTI,ANTÔNIO E.M.; ALVES,CASSIA C.F.; MIRANDA,MAYKER L.D..
Abstract Leishmaniasis is an endemic disease caused by protozoa of the genus Leishmania, which affects around two million people worldwide. One major drawback in the treatment of leishmaniasis is the emergence of resistance to current chemotherapeutics. Medicinal and aromatic plants constitute a major source of natural organic compounds. In this study, the leaf essential oil of Cryptocarya aschersoniana was obtained by hydrodistillation in a Clevenger-type apparatus, and the chemical composition was analyzed by GC-MS and GC-FID. The essential oil of these species was predominantly constituted by monoterpene hydrocarbons (48.8%). Limonene (42.3%), linalool (9.7%) and nerolidol (8.6%) were the main constituents in the oil of C. aschersoniana. The in vitro...
