Resumo: We studied the effect of Rhizophagus irregularis on plant performance and volatile terpenes content of the Mexican native medicinal plant Satureja macrostema (Benth.) Briq. (Lamiaceae) in greenhouse conditions. The growth parameters considered in this research and the composition of volatile components were quantified monthly in mycorrhizal and non-mycorrhizal plants. The essential oil was collected from aerial parts and analyzed by gas chromatography-mass spectrometry. Colonization by R. irregularis significantly increased biomass, shoot and root length, and the amount of volatile terpenes. The more concentrated volatile terpenes were limonene, β- linalool, menthone, pulegone, and verbenol acetate. It is concluded that the use of R. irregularis allows optimal growth of S. macrostema plants in low fertility soils and increased production of the main components of the essential oil.

El efecto de Rhizophagus irregularis sobre el rendimiento vegetal y la producción de los terpenos volátiles de Satureja macrostema (Benth.) Briq. (Lamiaceae), una planta medicinal nativa mexicana, fue estudiado en condiciones de invernadero. Los parámetros de crecimiento considerados en esta investigación y los componentes volátiles, fueron cuantificados mensualmente en plantas con y sin micorrizas. El aceite esencial fue colectado de la parte aérea y fue analizado por técnicas de cromatografía de gases-espectrometría de masas. La colonización de R. irregularis aumentó significativamente la biomasa, longitud de tallo y raíz, y la cantidad de terpenos volátiles. Los terpenos volátiles mayoritarios fueron limoneno, β-linalol, mentona, pulegona y acetato de verbenol. Se concluye que el uso de R. irregularis permitió un óptimo crecimiento de las plantas de S. macrostema en suelos de baja fertilidad, con un aumento de los componentes principales del aceite esencial.

Idioma: pt.
Resumo: O presente estudo teve por objetivo avaliar o efeito de BAP, na presença e ausência de ANA, sobre a multiplicação in vitro de segmentos apicais caulinares de Satureja hortensis. Os explantes foram isolados de plântulas germinadas in vitro e cultivados em meio nutritivo MS. O delineamento experimental utilizado foi o inteiramente casualizado, em esquema fatorial 2x5, correspondendo às concentrações de ANA (0 e 1 µM) e de BAP (0; 5; 10; 15 e 20 µM), com seis repetições, cada uma composta por três explantes. Para a porcentagem de explantes com brotações houve efeito significativo para o fator BAP, aumentando à medida que cresce a concentração da citocinina. A variável "número de brotos por explante" apresentou interação entre os fatores, havendo a maior formação de brotos na presença de ANA na faixa de 10 - 15 µM de BAP. Na presença da auxina, o maior valor ocorreu com 15 µM de BAP tendendo a diminuir independente da presença de ANA. O enraizamento dos segmentos apicais foi maior na presença de ANA e ausência de BAP, diminuindo com o aumento da citocinina. O número de folhas foi influenciado pela maior concentração de BAP sendo que a 15 µM foi observado o maior número, tendendo à queda com aumento da concentração. A concentração de 15 µM de BAP, independente de ANA, proporcionou os melhores resultados na multiplicação da espécie produzindo aumento de brotações e número de folhas, à exceção do enraizamento que foi influenciado pela auxina.

This study aimed to evaluate the effect of BAP in the presence and absence of NAA, on the in vitro multiplication of shoot apical segments of Satureja hortensis. The explants were isolated from seedlings germinated in vitro and cultured in nutrient medium MS. The experimental design was completely randomized in a 2x5 factorial arrangement, corresponding to the concentrations of NAA (0 and 1 µM) and BAP (0, 5, 10, 15 and 20 µM), with six replicates, each consisting of three explants. For the percentage of explants with shoots, there was no significant effect for the factor BAP, increasing as the concentration of BAP grows. The variable number of shoots per explant showed interaction between factors, with the highest shoot formation in the presence of NAA and BAP in the range of 10 -15 µM. In the presence of auxin, the highest value occurred with 15 µM BAP, tending to decline regardless of the presence of NAA. The rooting of the apical segments was higher in the presence of NAA and absence of BAP, decreasing with increasing cytokinin. Leaf number was influenced by the higher concentration of BAP, and the amount of 15 µMhadthe largest number, tending to decrease with increasing concentration. The concentration of 15 µM BAP, regardless of NAA, provided better results in the multiplication of the species, producing increased number of shoots and leaves, except for rooting, whichwas influenced by auxin.

Título: Antibacterial properties and chemical characterization of the essential oils from summer savory extracted by microwave-assisted hydrodistillation
Fonte: Braz. j. microbiol;42(4):1453-1462, Oct.-Dec. 2011. ilus, graf, tab.
Idioma: en.
Resumo: Antibacterial properties and chemical characterization of the essential oils from summer savory (Satureja hortensis) extracted by microwave-assisted hydrodistillation (MAHD) were compared with those of the essential oils extracted using the traditional hydrodistillation (HD) method. While MAHD at 660 W required half as much time as HD needed, similar antibacterial efficacies were found from the essential oils obtained by the two extraction methods on two food pathogens (Staphylococcus aureus, a gram positive bacterium, and Escherchia coli, a gram negative bacterium). Also, as it was the case with the essential oils extracted by HD, that of MAHD indicated greater influence on S. aureus than on E. coli. The compositions of the extracted essential oils were also studied using GC-MS analysis. The same components with negligible differences in their quantities were found in the extracted essential oils using the two methods outlined above. Overall, to reduce the extraction time, MAHD can be applied at higher microwave levels without any compromise in the antibacterial properties of the essential oils extracted.

Resumo: O Brasil dispõe de uma diversidade de substâncias naturais com propriedades terapêuticas bastante difundidas dentro da Odontologia Preventiva. Neste trabalho, objetivou-se avaliar a atividade antibacteriana das tinturas de jucá, aroeira, gengibre, alfavaca, própolis, romã e hortelã da folha graúda, sobre as linhagens de S. aureus (ATCC 25923), S. mutans (ATCC 2575), S. sobrinus (ATCC 27609), S. mitis (ATCC 9811), S. sanguis (ATCC 10557) e L. casei (ATCC 7469), utilizando-se a clorexldina 0,12% como controle positivo. Determinou-se a diluição inibitória máxima (DIM) em meio de cultura Agar Mueller Hlnton, das tinturas nas formas pura (1:0) e diluídas de 1:1 até 1:32. Observou-se susceptibilidade variada das bactérias, sendo o S. aureus o microorganismo mais sensível. Dentre as tinturas, o jucá, a aroeira e a própolis apresentaram uma significativa atividade antibacteriana sobre S. mutans, S. sobrinus, S. mitis, S. sanguis e L.casei, sendo que o gengibre e a alfavaca apresentaram os menores espectros de ação frente às linhagens bacterianas avaliadas.

Título: Pharmacological activity of the essential oil of Satureja viminea (Lamiaceae)
Fonte: Rev. biol. trop;51(1):247-252, mar. 2003. graf.
Idioma: en.
Resumo: The aqueous extract and the essential oil of Satureja viminea (Lamiaceae) were tested. General physiologic effects were assessed through the Hippocratic screening test. Non fasted female Sprague Dawley rats were utilized and 250, 500, 750 and 1000 mg/kg doses were used. Two animals were used for each dosage level and for the vehicle alone. Exploratory behavior and curiosity were measured using a hole board apparatus and placing non-trained mice on the board and recording the number of holes explored in a 5 minute period. The Boissier chimney test was used to evaluate motor coordination. Muscle strength was assessed through a grasping test where mice were hung by their fore-limbs 40 cm above the base on a horizontal metal stainless bar. In all these tests, 3 groups of 6 albino mice, were treated with 1000 mg/kg of each the essential oil of S. viminea, the vehicle and diazepan (1 mg/kg) as a positive control. Analgesic activity was explored in Sprague-Dawley rats. The tail flick method described by D'Amour and Smith (1941) modified by CYTED was implemented on three groups (6 rats each) of animals treated with, each the essential oil of S. viminea (1000 mg/kg), the vehicle and indomethacine. The test was carried out just before and 30, 60 and 120 min after oral treatment. Peristaltic activity was measured in albino mice, three groups of 6 animals each, treated orally with each the essential oil of S. viminea (1000 mg/kg), the aqueous extract (1000 mg/kg), and the vehicle. The marker used was activated carbon. Animals were sacrificed 30 min after the marker was given and the percent of total small intestine traversed by it was calculated. Also a lethal dose 50 (LD 50) was determined with the Spearman-Karber method. A dose-related spontaneous motor activity reduction was observed. Exploratory behavior and curiosity were diminished. The grasping strength of mice was reduced. A very clear and significant analgesic effect was observed with the oral administration of the essential oil of S. viminea (1000 mg/kg). This effect is compared to that of indomethacine. Intestinal transit and gastric emptying were inhibited by the essential oil. The LD50 of the essential oil of S. viminea is 556.8 mg/kg.
