Essential oils (EO) from aromatic and medicinal plants generally perform a diverse range of biological activities because they have several active constituents that work in different mechanisms action. EO Citrus peel an impressive food uses, besides other applications. reticulata, C. sinensis deliciosa were extracted fruit analyzed by GC-MS. The major constituent under evaluation was limonene, whose concentrations 98.54%, 91.65% 91.27% for sinensis, reticulata deliciosa, respectively....
Essential oils (EOs) are natural products widely used in sustainable agrochemistry, not only because they biodegradable and safe but also regarded as alternatives to chemical fungicides against fungal species that attack crops. Allelopathy, another field of study, falls within the most recent strategies applied weed suppression replace synthetic herbicides. Therefore, this study reports composition allelopathic antifungal effects EOs extracted from Calyptranthes concinna dried leaves (Cc-EO)...
In this study, the chemical composition and antibacterial antiproliferative potential of essential oil obtained from fresh leaves Psidium myrtoides (PM-EO) against oral pathogens human tumour cell lines were investigated for first time. GC-FID GC-MS analyses showed that trans-β-caryophyllene (30.9%), α-humulene (15.9%), α-copaene (7.8%), caryophyllene oxide (7.3%) α-bisabolol (5.3%) are major constituents PM-EO. The activity PM-EO a panel was in terms their minimal inhibitory concentrations...
RESUMOOs radicais livres e outros oxidantes demonstram ser parcialmente responsáveis pelo envelhecimento pelas doenças degenerativas associadas à produção de espécies reativas oxigênio. Além disto, os compostos fenólicos são reconhecidamente detentores elevada atividade antioxidante, que geralmente estão envolvidos em tratamentos problemas pigmentação da pele, resultam hiperpigmentações. Sendo assim este trabalho foi realizado para avaliar o conteúdo fenóis totais, antioxidante a capacidade...
This study aimed at determining antibacterial activities of three essential oils (EOs) and their major constituents against foodborne pathogenic bacteria food spoilage ones. The EOs were tested by the broth microdilution method on 96-well microplates, followed minimum inhibitory concentration (MIC) bactericidal (MBC) (µg/mL) determination. from Psidium cattleianum Sabine, Cryptocarya aschersoniana Mez. Ocotea dispersa Nees (Mez.) leaves showed strong activity since MIC MBC values ranged...
Food loss due to contamination caused by fungi has much impact on agriculture and leads significant economic losses. Synthetic natural fungicides have been used for avoiding losses of several food products fungal contamination. As a result, species the genus Capsicum preserving because their chemical compounds with antifungal activity. Therefore, this study aimed at identifying some phenolic found in both ethyl acetate extract (EAE) methanolic (ME) from habanero pepper (C. chinense) ripe...
This paper aims to investigate, for the first time, physicochemical characteristics and antioxidant capacity of Psidium myrtoides ripe unripe fruit. In addition, essential oil was extracted from fresh leaves (PM-EO) collected in dry rainy seasons investigate influence seasonality and, after that, evaluate its antifungal activity on mycelial growth Colletotrichum gloeosporioides. Both GC-FID GC-MS analyses revealed that major components determined PM-EO were β-caryophyllene (20.0% 32.9%)...
HIGHLIGHTS Tradescantia pallida has shown promising antibacterial, antioxidant and anticancer activities. Botanical extract products are environmentally friendly, inexpensive may reduce losses by discouraging pathogen growth. HE-TP was highly active in vitro assays against P. digitatum, S. sclerotiorum R. stolonifer. demonstrated cytotoxic activity different human tumor cell lines. The major compound identified hexane from T. (E)-4-methoxycynnamic acid (50.2%).
In this study, the chemical composition and in vitro antileishmanial activity of essential oils (EOs) from Protium heptaphyllum fresh young (PY-EO) adult (PA-EO) leaves against promastigote forms Leishmania amazonensis were evaluated. PY-EO PA-EO highly active activeagainst L. amazonensis, since IC50 = 9.02 28.88 μg/mL, respectively. Chemical constituents identified by GC-MS GC-FID. β-Caryophyllene (15.1%), α-amorphene (9.4%) α-copaene (8.1%) major PY-EO, whereas onlyβ-caryophyllene (15.0%),...
Abstract Mosquito-borne diseases are prevalent in more than 100 countries across the world. They major vectors for transmission of Malaria, dengue, yellow fever, filariasis, schistosomiasis, Japanese encephalitis etc. Many formerly employed insecticides mosquito control have harmful effects on human health and other non-target populations, their non-biodegradable nature, higher rate bio-magnification our ecosystem increasing insecticide resistance global scale raising serious concerns. ....
