| Lippia alba, espécie brasileira da família Verbenaceae, é plantada e usada em todo o Brasil por suas atividades farmacológicas como analgésica, antiespasmódica, calmante, sedativa e citostática. Popularmente a Lippia é denominada de alecrim, cidreira falsa ou falsa melissa. O trabalho visou testar o efeito das aplicações de GA3, ethephon e CCC sobre o crescimento de Lippia alba (Mill.) N.E.Br. - Verbenaceae, em diferentes épocas do ano. O experimento foi instalado na Fazenda São Manuel, pertencente à UNESP em Botucatu, de dezembro/95 a dezembro/96. O mesmo consistiu de sete tratamentos e três repetições em blocos inteiramente casualizados, com os tratamentos aplicados nas parcelas e as colheitas nas subparcelas. Os tratamentos incluíram o controle, ácido... |

| ABSTRACT: The rise in cases of antibiotic-resistant Mycobacterium tuberculosis has become a major obstacle to the effective control of tuberculosis (TB) worldwide. Essential oils (EO) are complex mixtures that may contain between 20 and 60 components, with two or three major compounds at relatively high concentrations (20-70%) that are responsible for their pharmacological properties. The objective of this study was to assess the antimicrobial activity of the EOs, bushy lippia (Lippia alba), rosemary pepper (Lippia sidoides), lemon grass (Cymbopogon citratus), Mexican mint or Indian borage (Plectranthus amboinicus), and true cinnamon (Cinnamomum zeylanicum), against Mycobacterium tuberculosis H37Rv. Chemical characterization of the EOs was performed by gas... |

| Lippia alba (Mill.) N.E. Brown (Verbenaceae) is widely used in different regions of Central and South America as a tranquilizer. The plant’s anxiolytic properties, however, merit investigation. The present study evaluated the effects of repeated daily (14 days) intraperitoneal (ip) treatment with an essential oil (EO) from a chemotype of L. alba (LA, chemotype II, 12.5 and 25 mg/kg; N = 6-8) and (R)-(-)-carvone (25 mg/kg; N = 8-12), the main constituent of this chemotype, on male Wistar rats (weighing 250 g at the beginning of the experiments) submitted to the elevated T-maze (ETM). The ETM allows the measurement of two defensive responses: inhibitory avoidance and one-way escape. In terms of psychopathology, these responses have been related to... |

| Com o objetivo de avaliar o comportamento agronômico, o potencial de rendimento de óleo essencial e identificar os quimiotipos de 16 acessos de Lippa alba (erva cidreira) da coleção da Universidade de Brasília foi conduzido um experimento de campo em Latossolo Vermelho, sob irrigação por gotejamento na região do Cerrado do Distrito Federal. Foram avaliados a época de florescimento, hábito de crescimento, área foliar, comprimento da haste, massa fresca de folhas e hastes, massa foliar seca, teor e rendimento de óleo essencial e perfil aromático. O óleo essencial foi extraído por hidrodestilação em aparelho de Clevenger modificado e os constituintes identificados e quantificados através de cromatografia em fase gasosa acoplada a espectrometria de massas.

| ABSTRACT The aim of this study was to evaluate the effect of light quality and nitrogen availability on the biomass production, yield and composition of essential oil of lemon balm (Lippia alba). Five doses of N (0; 40; 80; 120 and 160 kg ha-1) were studied, using urea and three light quality conditions obtained with the use of colored shading nets (blue and red), 50% irradiance and under full sun. The experiment was arranged in a 5x3 factorial scheme, in split plots, with seven replicates. After 60 days of cultivation under the shading nets, a higher dry leaf biomass (4.83 g per plant) was observed in the plants under blue net cultivation at a dose of 102 kg ha-1 of N. The plants grown under full sun presented greater amount of neral and geranial, major... |

| The present work evaluated the chemical composition and the DNA protective effect of the essential oils (EOs) from Lippia alba against bleomycin-induced genotoxicity. EO constituents were determined by Gas Chromatography/Mass Spectrometric (GC-MS) analysis. The major compounds encountered being citral (33% geranial and 25% neral), geraniol (7%) and trans-β-caryophyllene (7%) for L. alba specimen COL512077, and carvone (38%), limonene (33%) and bicyclosesquiphellandrene (8%) for the other, COL512078. The genotoxicity and antigenotoxicity of EO and the compounds citral, carvone and limonene, were assayed using the SOS Chromotest in Escherichia coli. The EOs were not genotoxic in the SOS chromotest, but one of the major compound (limonene) showed genotoxicity... |

| We aimed to establish the period of time required for seedlings formation, as well as to evaluate the effect of substrates and plant growth regulators in cuttings of L. alba. Three experiments were performed, with statistical designs chosen according to each test objectives. Rooting (%), shoot height (cm), longest root length (cm), leaves number, fresh and dry matter masses (g), were analyzed. The absolute rate of shoot and root system growth, together with the relationship between dry mass of roots and shoots were efficient in predicting the period of greatest speed and accumulation of organic matter in plants. The plant growth regulators favored the vegetative performance of seedlings, with better development 30 days after the cuttings containing mineral... |

| Lippia alba is empirically used for infusions, teas, macerates, and hydroalcoholic extracts because of its antispasmodic, analgesic, sedative, and anxiolytic effects. Citral is a mixture of trans-geranial and cis-neral and is the main constituent of L. alba essential oil and possesses analgesic, anxiolytic, anticonvulsant, and sedative effects. The present study evaluated the effects of the essential oil of L. alba (EOLa) and citral on compound action potentials (CAPs) in Wistar rat sciatic nerves. Both drugs inhibited CAP in a concentration-dependent manner. The calculated half-maximal inhibitory concentrations (IC50) of peak-to-peak amplitude were 53.2 µg/mL and 35.00 µg/mL (or 230 µM) for EOLa and citral, respectively. Peak-to-peak amplitude of the CAP... |

| A Lippia alba é uma planta medicinal nativa da América do Sul muito utilizada pela sua propriedade calmante. No presente trabalho estudou-se a propagação vegetativa dessa espécie, visando a obtenção de uma forma eficiente de formação de mudas. Foram testados diferentes tipos de estaca (medianas com 4 folhas, medianas com 2 folhas, medianas sem folhas e apicais), tamanhos de estacas lenhosas (5, 10, 15 e 20cm) e substratos (casca de arroz carbonizada, vermiculita, solo e Plantmax®). Todos os tipos de estaca apresentaram altas taxas de enraizamento, comprovando que a L. alba é uma espécie de fácil enraizamento. As estacas medianas com quatro folhas foram as que apresentaram o maior desenvolvimento radicial, ao contrário das estacas sem folhas. As estacas com... |

| Lippia alba is a shrub of the Verbenaceae family, popularly known as lemon balm. It's essential oil is said to have broad-spectrum antimicrobial activity whose effectiveness varies according to its composition, which is influenced by both biotic and abiotic factors. The present study aimed to evaluate the antimicrobial effectiveness of oil taken from the leaves of L. alba collected at different times of the year, against microorganisms of importance in food. The oil, obtained by hydrodistillation, was tested against standard cultures of Pseudomonas aeruginosa, Salmonella choleraesuis, Escherichia coli, Staphylococcus aureus, Listeria monocytogenes and Listeria innocua using agar diffusion techniques. The different sampling times had a big influence on the... |

| The essential oil (EO) of Lippia alba (Mill.) N. E. Brown (Verbenaceae) has been traditionally used to treat several diseases. In this study, the acute toxic effects of the citral chemotype of L. alba EO were evaluated in mice. Animals were treated via intraperitoneal receiving the L. alba essential oil at doses between 50 and 2500 mg/kg, and the control group received sesame oil (vehicle). The EO induced dose-dependent neurotoxic effects at doses greater than 1000 mg/kg, including decreased locomotion, motor skills and muscle strength, hypotonia, dyspnea, kyphosis and convulsions. The EO was lethal at a dose of 2500 mg/kg. Animals receiving 1000 mg/kg were euthanized at the end of the treatment period and their blood and livers were collected for... |
