“…Due to the medicinal importance or toxic effects of several species of Verbenaceae, efforts have been made to develop markers that allow distinguishing among species. Some of these efforts have focused on anatomical studies (Calzada-Sánchez et al, 2014;Passos et al, 2009).…”

The family Verbenaceae hosts important species used in traditional medicine of many countries. The taxonomic controversies concerning the specific delimitation of several of its species make it difficult to guarantee the botanical origin of herbal preparations based on species of this family. To contribute to the development of both specific chemomarkers and a quality control tool to authenticate the botanical origin of herbal preparations of Verbenacea species, we determined the foliar HPLC-DAD phenolic profiles and the antioxidant properties of 10 wild species of this family occurring in Mexico. The contents of phenols and flavonoids varied significantly among species. Priva mexicana showed the highest levels of total phenolics (53.4 mg g -1 dry tissue) and Verbena carolina had the highest levels of flavonoids (17.89 mg g -1 dry tissue). Relevant antioxidant properties revealed by antiradical and reducing power were found for the analyzed species. These properties varied significantly in a species-dependent manner. The phenolic compounds accumulated were flavones and phenolic acids. Flavones were the only type of flavonoids found. The results of a cluster analysis showed that the compounds were accumulated in species-specific profiles. The phenolic profiles are proposed as valuable chemomarkers that can become a useful tool for the quality control concerning the botanical origin of herbal medicinal preparations based on the species analyzed. In addition, phenolic profiles could contribute importantly to solve the taxonomic controversies concerning species delimitation in the family Verbenaceae.Keywords: Verbenacea, antioxidant activity, chemomarkers, flavones, phenolic profiles. Compostos fenólicos das folhas de dez especies selvagem de Verbenaceae como antioxidantes e quimiomarcadores específicos ResumoA família Verbenaceae compreende importantes espécies utilizadas na medicina popular de muitos países. As dificuldades taxonômicas relativas à delimitação específica de muitas das suas espécies face difícil a verificar a origem botânico das preparações herbales baseadas nas espécies desta família. Para fazer uma contribuição ao desenvolvimento de indicadores taxonômicos e dum método de controle de qualidade para verificar a origem botânico de preparações herbales das espécies de Verbenaceae, os perfis fenólicos, obtidos pares HPLC-DAD, e as atividades antioxidantes das folhas de 10 espécies selvagens Mexicanas desta família foram determinados. Os conteúdos dos compostos fenólicos totais e dos flavonoides foram significativamente diferentes entre as espécies. Priva mexicana apresentou a maior quantidade de compostos fenólicos totais (53.4 mg g -1 amostra seca) e Verbena carolina apresentou a maior quantidade de flavonoides (17.89 mg g -1 amostra seca). Verifica-se importantes propriedades antioxidantes, como os resultados dos ensaios da capacidade antiradical e do poder redutor indicaram. As propriedades antioxidantes foram significativamente diferentes entre as espécies. Verificou-se que os compostos fe...

Resumen: Actualmente Aloysia triphylla, Lantana camara, Lippia dulcis, Verbena bipinnatifi da, V. carolina y V. litoralis, se encuentran en lista de espera para su inclusión en la Farmacopea Herbolaria de los Estados Unidos Mexicanos. Con la fi nalidad de contribuir a dicha incorporación y a su identifi cación, en el presente estudio se compararon caracteres morfo-anatómicos de la hoja, tallo y ramas, de estas seis especies de Verbenaceae empleadas en la medicina tradicional mexicana. Se reconocen dos tipos de tricomas simples y nueve glandulares capitados, estos varían en el número y tamaño de células del pedúnculo y número de células de la cabeza. Caracteres anatómicos foliares distinguen notablemente a A. triphylla de las demás especies. La forma de la hoja, la combinación de tipos de tricomas glandulares y las características anatómicas de la vena media y el pecíolo son las de mayor valor diagnóstico. Palabras clave: Aloysia, anatomía vegetal, Lantana, Lippia, plantas medicinales, Verbena.Abstract: Currently, Aloysia triphylla, Lantana camara, Lippia dulcis, Verbena bipinnatifi da, V. carolina, and V. litoralis, are in the waiting for list to be included in the Herbal Pharmacopoeia of the United Mexican States. In order to contribute for incorporation and identifi cation of these species, in this study, anatomical vegetative characters, leaf and stem, of these six Verbenaceae used in Mexican traditional medicine, were compared. Two types of simple and nine capitate glandular trichomes are recognized. Glandular trichomes vary in number cells and size in the stalk, as well as in number cell in the head. Leaf anatomical characters of A. triphylla differ from the other species. The lamina shape, combination of types of glandular trichomes and anatomical features in midrib and petiole are the ones with higher diagnostic value in species recognition.

“…However, L camara has ornamental uses, and is reported to improve soil quality for agriculture as well as possessing insecticide, antifungal, and herbicide activities. In folk medicine, this species is known by its sudorific and antipyretic activities, action on bronco-lung problems, rheumatism and against scabies (Patel, 2011;Passos et al, 2009;Lorenzi, 2008;Kohli et al, 2006;Lorenzi, 2002). The essential oil of its flowers and leaves possess a variety of chemical compounds with leishmanicidal, antimicrobial, anticancer, antiulcer, anti-inflammatory activities, among others.…”

Lantana camara L. is considered a weed, but is used in agriculture and traditional medicine due to its different pharmacological effects. The objective of this study was to determine the chemical composition and the bioactivity of essential oil from L. camara flowers collected in Boa Vista, Roraima, Brazil. Essential oil was obtained using a Clevenger type apparatus. The oil obtained was analyzed by gas chromatography coupled to flame ionization detector (GC-FID) and gas chromatography coupled to mass spectrometer detector (GC-MS) and its bioactivity was assayed against fungi and bacteria, as well as for acetylcholinesterase inhibition. The chemical composition of essential oil presented major compounds contrasting with the literature, while its bactericidal and fungicidal activity was excellent, reaching over than 90% inhibition against yeast. A potent anti-acetylcholinesterase activity, superior than 77% inhibition, was also observed.
