Tradescantia pallida is an ornamental plant widely found in flowerbeds and urban gardens. However, information about the physiological and biochemical responses of this ornamental plant to herbicides is scarce. Therefore, this work aimed to evaluate the toxicity, regrowth capacity, growth, physiology, and alterations in the metabolism of T. pallida after the application of different herbicide classes. The treatments consisted of spraying the herbicides: atrazine (1,500 g ha-1), diquat (300 g ha-1), carfentrazone (10 g ha-1), glyphosate (1,500 g ha-1), and 2,4-D (1,050 g ha-1) on T. pallida. Plants sprayed only with water represented the control group. The evaluations were carried out five days after the application of the herbicides. The evaluated variables were visual toxicity and regrowth index, chlorophyll a fluorescence, chlorophyll content (a, b and a + b), carotenoids and proline content. The herbicide 2,4-D did not act on the plant, but it may have produced a genotoxic effect. Glyphosate significantly increased the proline content and generated zero regrowth index, showing the plant's sensitivity to the herbicide. Carfentrazone was not fully effective in controlling T. pallida, which also did not show sensitivity to atrazine, but high sensitivity to diquat, despite the low proline content found. The different classes of herbicides act differently in terms of toxicity, regrowth, physiology and metabolism of T. pallida, these being useful variables to investigate the possible tolerance of plants to the different classes of herbicides. Tradescantia pallida es una planta ornamental que se encuentra ampliamente en parterres y jardines urbanos. Sin embargo, la información sobre las respuestas fisiológicas y bioquímicas de esta planta ornamental a los herbicidas son escasas. Por lo tanto, este trabajo tuvo como objetivo evaluar la toxicidad, capacidad de rebrote, crecimiento, fisiología y alteraciones en el metabolismo de T. pallida luego de la aplicación de diferentes clases de herbicidas. Los tratamientos consistieron en la aspersión de los herbicidas: atrazina (1,500 g ha-1), diquat (300 g ha-1), carfentrazona (10 g ha-1), glifosato (1,500 g ha-1) y 2,4-D (1.050 g ha-1) sobre T. pallida. Las plantas rociadas solo con agua representaron el grupo de control. Las evaluaciones se realizaron 5 días después de la aplicación de los herbicidas. Se evaluó toxicidad visual e índice de rebrote, fluorescencia de clorofila a, contenido de clorofila (a, b y a + b), carotenoides y prolina. El herbicida 2,4-D no actuó sobre la planta, pero pudo haber producido un efecto genotóxico. El glifosato aumentó significativamente el contenido de prolina y generó un índice de crecimiento cero, lo que muestra la sensibilidad de la planta al herbicida. La carfentrazona no fue completamente efectiva en el control de T. pallida, que tampoco mostró sensibilidad a la atrazina, pero sí una alta sensibilidad al diquat, a pesar del bajo contenido de prolina encontrado. Las diferentes clases de herbicidas actúan de manera diferente en términos de toxicidad, rebrote, fisiología y metabolismo de T. pallida, variables útiles para investigar la posible tolerancia de las plantas a las diferentes clases de herbicidas. Tradescantia pallida é uma planta ornamental amplamente encontrada em canteiros e jardins urbanos.

Plantas pulverizadas somente com água representaram o grupo controle. As avaliações foram realizadas 5 dias após a aplicação dos herbicidas. Foi avaliado a toxicidade visual e índice de rebrota, fluorescência da clorofila a, conteúdo de clorofilas (a, b e a+b), carotenoides e prolina. O herbicida 2,4-D não atuou sobre a planta, mas pode ter produzido efeito genotóxico. Glifosato aumentou significativamente o teor de prolina e gerou índice zero de rebrota, evidenciando sensibilidade da planta ao herbicida. Carfentrazone não foi totalmente eficiente sobre o controle de T. pallida, que também não demonstrou sensibilidade a atrazina, mas alta sensibilidade a diquat, apesar do baixo teor de prolina verificado. As diferentes classes de herbicidas atuam de maneira diferente quanto à toxidez, rebrota, fisiologia e metabolismo de T. pallida, sendo estas, variáveis úteis para investigar a possível tolerância de plantas às diferentes classes de herbicidas.

The objective of the present work was to determine the antioxidant potential of the essential oil of the leaves of Campomanesia xanthocarpa. The technique used for the extraction of the essential oil was hydrodistillation using the Clevenger apparatus and the identification of the chemical composition of the essential oil by gas chromatography coupled to the mass spectrometry (GC-MS). The antioxidant potential was measured by 2,2-diphenyl-1-picrylhydrazyl (DPPH•), ferric ion reducing antioxidant power (FRAP), and β-carotene/linoleic acid co-oxidation. By GC-MS analysis, 47 compounds were identified, and the major class was the hydrocarbon sesquiterpenes (46.80%) with the major compounds: bicyclogermacrene (8.29%); globulol (5.67%); τ-murolol (5.59%); β-karyophylene (5.28%); germacrene D (5.03%); δ-cadinene (4.76%); τ-cadinol (4.51%) and linalool (4.17%). The results found for the antioxidant activity by β-carotene/linoleic acid co-oxidation system indicated that the essential oil of C. xanthocarpa showed a high antioxidant potential at 1.00 mg/mL and an intermediate potential at the other concentrations tested. The antioxidant activity of the essential oil by the FRAP method was 3.83 ± 1.99 µMol Fe+2/mg. Therefore, the oil essential from C. xanthocarpa leaves showed antioxidant potential by β-carotene/linoleic acid co-oxidation system, and FRAP, encouraging the inclusion of this species in the list of natural antioxidants for application in the food, cosmetic and pharmaceutical fields. El objetivo del presente trabajo fue determinar el potencial antioxidante del aceite esencial de las hojas de Campomanesia xanthocarpa. La técnica utilizada para la extracción del aceite esencial fue la hidrodestilación mediante el aparato de Clevenger y la identificación de la composición química del aceite esencial mediante cromatografía de gases acoplada al espectrómetro de masas. El potencial antioxidante se midió mediante los métodos de secuestro de radicales libres del radical 2,2-difenil-1-picrilhidrilo (DPPH•), mediante el sistema de co-oxidación β-caroteno/ácido linoleico y mediante el método de reducción de hierro (FRAP). Mediante análisis de cromatografía de gases junto con espectrometría de masas se identificaron 47 compuestos, y la clase principal fueron los sesquiterpenos de hidrocarburos (46,80%) con los compuestos principales biciclogermacreno (8,29%); globulol (5,67%); τ-murolol (5,59%); β-cariofileno (5,28%); germacreno D (5,03%); δ-cadineno (4,76%); τ-cadinol (4,51%) y linalol (4,17%). Los resultados encontrados para la actividad antioxidante del sistema de co-oxidación β-caroteno/ácido linoleico indicaron que el aceite esencial de C. xanthocarpa tiene un alto potencial antioxidante a 1,00 mg/mL y un potencial intermedio a las otras concentraciones probadas. La actividad antioxidante del aceite esencial por el método FRAP fue de 3,83 ± 1,99 µMol Fe+2/mg. Por lo tanto, el aceite extraído de las hojas de C. xanthocarpa mostró potencial antioxidante por el método de co-oxidación betacaroteno/ácido linoleico y FRAP, fomentando la inclusión de estaespecie en la lista de antioxidantes naturales para su aplicación en los campos alimentario, cosmético y farmacéutico. O objetivo do presente trabalho consistiu na determinação do potencial antioxidante do óleo essencial das folhas de Campomanesia xanthocarpa. A técnica utilizada para a extração do óleo essencial foi a hidrodestilação utilizando o aparelho de Clevenger e a identificação da composição química do óleo essencial por cromatografia em fase gasosa acoplado ao espectrômetro de massas. O potencial antioxidante foi mensurado pelos métodos de sequestro dos radicais livres do radical 2,2 difenil-1-picrilhidrazil (DPPH•), pelo sistema de co-oxidação β-caroteno/ácido linoleico e pelo método de redução do ferro (FRAP). Pela análise de cromatografia em fase gasosa acoplada à espectrometria de massas foram identificados 47 compostos, e a classe majoritária foram os sesquiterpenos hidrocarbonetos (46,80%) com os compostos majoritários biciclogermacreno (8,29%); globulol (5,67%); τ-murolol (5,59%); β-cariofileno (5,28%); germacreno D (5,03%); δ-cadineno (4,76%); τ-cadinol (4,51%) e linalol (4,17%). Os resultados encontrados para a atividade antioxidante pelo sistema de co-oxidação β-caroteno/ácido linoleico indicaram que o óleo essencial de C. xanthocarpa apresenta alto potencial antioxidante na concentração 1,00 mg/mL e potencial intermediário nas demais concentrações testadas. A atividade antioxidante do óleo essencial pelo método FRAP foi de 3,83 ± 1,99 µMol Fe+2/mg. Portanto, o óleo extraído das folhas de C. xanthocarpa apresentou potencial antioxidante pelo método de co-oxidação do beta-caroteno/ácido linoleico e FRAP, encorajando a inclusão desta espécie na lista dos antioxidantes naturais para aplicação na área de alimentos, cosmética e farmacêutica.

Tetradenia riparia is known for its richness in essential oil which has been widely investigated due to its biological activities such as antimicrobial, insecticidal, trypanocidal, antimalarial and antioxidant. The objective of this work was to chemically analyze and evaluate the antifungal and antimycotoxigenic activity of the essential oil and the crude extract of leaves, flower buds and stems of T. riparia from the northwest region of the state of Paraná. The essential oil was obtained by hydrodistillation using a Clevenger-type apparatus. To obtain the crude extract, the leaves, flower buds and stems were pulverized and subjected to a dynamic maceration process using 70% v v−1 ethyl alcohol. Chemical analysis of the essential oil was performed by GC/MS, and chemical identification of the crude extract by UHPLC-ESI/qTOF. Antifungal activity (Rhizopus oryzae, Aspergillus flavus, Aspergillus ochraceus, Penicillium verrucosum and Fusarium graminearum) was performed by broth microdilution and the antimycotoxigenic assay was performed with A. ochraceus and P. verrucosum. Ochratoxin A was extracted by partition with chloroform and quantified by HPLC-FL. The oil yield was 0.29% for leaves, 0.34% for stems and 0.38% for flower buds, and the major compounds were fenchone, β-caryophyllene, α-cadinol, 14-hydroxy-9- epi-caryophyllene, 9β,13β-epoxy-7-abietene, α-cadinol and 6–7-dehydroroyleanone. The main chemical compounds identified in the crude extract were terpenes, anthocyanins, flavonoids, tannins and phenolic acids. The minimum inhibitory concentration (MIC) of oils from leaves, flower buds and stems for the strains tested ranged from 0.87 mg mL−1 to 33.3 mg mL−1, while the minimum fungicidal concentration (MFC) ranged from 6.94 mg mL−1 and 33.3 mg mL−1. The MIC and MFC for ketoconazole, tebuconazole, sorbate and nitrite ranged from 0.05 to 33.3 mg mL−1. The oil and crude extract of leaves, stems and flower buds showed an inhibition of ochratoxin A production for P. verrucosum of approximately 100%. [ABSTRACT FROM AUTHOR]

Os sanitizantes químicos tradicionais utilizados na indústria de alimentos apresentam, como desvantagem, o possível desenvolvimento de resistência e adaptação bacteriana, interferindo na eficiência bactericida mínima destes produtos. Os óleos essenciais com atividade antimicrobiana despertam grande interesse na indústria de alimentos, pela possível utilização como princípios ativos de sanitizantes. Esta pesquisa objetivou determinar a concentração inibitória mínima (CIM) dos óleos essenciais (OEs) de cravo-da-índia e canela contra bactérias Gram positivas (Staphylococcus aureus e Listeriamono cytogenes) e Gram negativas (Escherichia coli e Salmonella sp.) e compará-la com a CIM do hipoclorito de sódio, além de determinar a concentração bactericida mínima (CBM) dos OEs para L. monocytogenes. Foi utilizado o método da microdiluição e os OEs foram caracterizados, quimicamente, por cromatografia gasosa - espectrometria de massa. Os componentes principais dos OEs de canela e cravo-da-índia foram o cinamaldeído (67,58%) e o eugenol (77,58%), respectivamente. A CIM do OE de canela foi de 0,04%, para as bactérias Gram positivas, e < 0,02%, para a bactérias Gram negativas. O OE de cravo-da-índia teve CIM de 0,04% para Salmonella sp., 0,06% para E. coli e S. aureus e 0,08% para L. monocytogenes. Para todas as bactérias testadas, a CIM do hipoclorito de sódio foi > 0,2%. A CBM para L. monocytogenes, no OE de cravo-da-índia, foi de 0,18% e o OE de canela destacou-se por apresentar CBM < 0,02%, demonstrando a possibilidade do uso destes OEs, principalmente o de canela, como princípios ativos de sanitizantes. The traditional chemical sanitizers used in the food industry have the disadvantage of a possible development of bacterial resistance and adaptation, interfering with their minimum bactericidal efficiency. Essential oils with antimicrobial activity arouse great interest in the food industry for their possible use as active ingredients of sanitizers. This study aimed to determine the minimum inhibitory concentration (MIC) of cinnamon and clove essential oils (EOs) against Gram-positive (Staphylococcus aureus and Listeriamono cytogenes) and Gram-negative (Escherichia coli and Salmonella sp.) bacteria, as well as compare it with the MIC of sodium hypochlorite, and to determine the minimum bactericidal concentration (MBC) of EOs for L. monocytogenes. The microdilution method was used and the EOs were chemically characterized by gas chromatography - mass spectrometry. The main components of the cinnamon and clove EOs were respectively cinnamaldehyde (67.58%) and eugenol (77.58%). The cinnamon EO MIC was 0.04% for Gram-positive bacteria and < 0.02% for Gram-negative bacteria. The clove EO showed MIC of 0.04% for Salmonella sp., 0.06% for E. coli and S. aureus and 0.08% for L. monocytogenes. For all bacteria tested the sodium hypochlorite MIC was > 0.2%. The MBC for L. monocytogenes of the clove EO was 0.18%, while the cinnamon EO distinguished itself for presenting MBC < 0.02%, demonstrating the possibility of using these EOs, especially the cinnamon one, as active principles of sanitizers.
