RESUMO:Foram avaliadas a ação antioxidante, ação antimicrobiana e a composição dos óleos essenciais de cravo-da-índia (Caryophillus aromaticus L.), citronela (Cymbopogon winterianus) e palmarosa (Cymbopogon martinii). A ação antioxidante foi avaliada pelo método de DPPH (2,2-difenil-1-picril-hidrazila), e a ação antimicrobiana determinada pelo método da microdiluição definindo-se a concentração inibitória mínima para os microrganismos Staphylococcus aureus, Escherichia coli, Salmonella Thyphimurium, Pseudomonas aeruginosa e Clostridium perfringens. A composição química dos óleos foi determinada por CG-DIC e a identificação dos compostos voláteis por CG-EM, em ambos os casos, utilizando uma coluna capilar DB-5. O óleo de cravoda-índia apresentou uma forte atividade antioxidante e ação antimicrobiana moderada a forte, sendo o eugenol o componente majoritário do óleo de cravo-da-índia (83,7%). Por outro lado, as amostras de citronela e palmarosa apresentaram fraca ação antioxidante, porém a ação antimicrobiana foi moderada a forte.Palavras-chave: radicais livres, cravo-da-índia, óleos essenciais, antioxidantes ABSTRACT: Composition and antioxidant and antimicrobial activities of clove, citronella and palmarosa essential oils. Antioxidant and antimicrobial activities, as well as the chemical composition of essential oils of clove (Caryophillus aromaticus L.), citronella (Cymbopogon winterianus) and palmarosa (Cymbopogon martinii) were studied. Antioxidant activity was evaluated by DPPH (2,2-diphenyl-1-picrylhydrazyl) method and the antimicrobial activity determined by the microdilution method. The minimal inhibitory concentration was defined against Staphylococcus aureus, Escherichia coli, Salmonella Thyphimurium, Pseudomonas aeruginosa and Clostridium perfringens. The chemical composition of oils was determined by GC-FID and volatile compounds were identified by GC-MS, using a DB-5 fused silica capillary column. Clove essential oil showed very high antioxidant activity and moderate to high antimicrobial activity, and eugenol was its major compound (83.7%). On the other hand, citronella and palmarosa samples presented low antioxidant activity but showed moderate to high antimicrobial activity.

“…1) and a major component of essential oils from spices such as neroli (Citrus aurantium), rose (Rosa damascena), and lavender (Lavandula dentata, Lavandula stoechas and Lavandula multifida) (Chintaluri, Komarraju, Chintaluri, & Vemulapalli, 2015;Kumar, Sharma, Sood, & Agnihotri, 2013;Msaada et al, 2012). Its antimicrobial activity has been recently proven against some gram-positive and gram-negative bacteria, as well as the Candida albicans and Aspergillus flavus (Jirovetz et al, 2007;Tian et al, 2013), showing a high potential to improve the shelf life and safety of perishable foods (Holley & Patel, 2005). However, no reports about the effects of NEL on A. niger contamination in table grapes during storage have yet been published, and possible mechanisms of antifungal action of NEL on A. niger remain to be established.…”

ABSTRACT. In this study, the temperature and pressure of supercritical CO 2 extraction were evaluated to obtain oleoresin of Brunfelsia uniflora leaves and flowers. The oleoresin compounds were identified by gas chromatography-mass spectrometry. The antioxidant activity was evaluated by three different methods. The highest oleoresin yields were 3.32% at 40°C and 200 bar for the leaves, and 1.03% at 60°C and 200 bar for the flowers. The main extracted compounds from leaves were phytol varying from 11.95 to 36.42% and α-tocopherol from 15.53 to 43.10%, and from flowers were geranyl linalool from 11.05 to 21.42% and α-amyrin from 9.66 to 22.12%. Oleoresin obtained at 60°C and 150 bar from leaves presented high antioxidant activity by DPPH (IC 50 1.90 mg/mL) and by FRAP (1.8 µmol Fe 2+ /mg). β-carotene/linoleic acid co-oxidation oleoresin from leaves at 0.25 mg/mL presented higher antioxidant activity than Trolox. The total phenolic content of the oleoresin from leaves ranged from 66.20 to 83.33 µg/mg and from flowers it was just up to 12.46 µg/mg. The extraction conditions affected yield, chemical composition, and antioxidant activity of oleoresin from leaves and flowers. This is the first report on the antioxidant activity of B. uniflora oleoresin from leaves and flowers and provides subsidies for potential applications in chemical, pharmaceutical, and food industries.
