“…Our results are only partly in agreement with data previously reported for collections from Argentina and Perú (Zygadlo et al, 1993;De Feo et al, 2005;López et al, 2011). These facts indicate the existence of a high chemical plasticity in Tagetes as demonstrated by Zygadlo et al (1990) and Gil et al (2000Gil et al ( , 2002. In general, different growth stages of the plant exhibit variations in their essential oil composition (Chamorro et al, 2008).…”

“…Similarly chemotypes can be found as result of intraspecific variations when the essential oil composition of individual plants of the same population are compare, other differences can arise as a result of the plant response to environmental conditions i.e. growth locations (Zygadlo et al, 1990;Gil et al, 2000). Thus further studies with a larger number of individuals from a same population and from other Tagetes populations in different phenological stages are necessary in order to determinate quantitative, qualitative, inter and intraspecific variations in their essential oils composition.…”

“…Plants coming from Buenos Aires showed cis-tagetone, dihydrotagetone and cis-β-ocimene approximately 20% each; plants obtained from Jujuy showed significant amounts of cis-β-ocimene (26%), cis-tagetone (19%), cistagetenone (17%) and trans-tagetenone (12%); and a collection from Salta showed high amounts of trans-β-ocimene (34%) and α-phellandrene (29%) (Gil et al, 2000;Vázquez et al, 2011). Essential oils of Tm collected in various localities of Cordoba province were dominated by cis and trans-ocimene, cis and trans-tagetenone, and cis-and trans-tagetone (Zygadlo et al, 1990) while collections from Chaco contain mostly dihydrotagetone accompanied by β-ocimene, tagetone and tagetenone (Chamorro et al, 2008).…”

Summary:The essential oil composition and morpho-anatomy of Tagetes minuta, collected at "El Mollar" and two different populations of Tagetes terniflora collected in Tafí del Valle (Tucumán, Argentina) were studied. The essential oil of aerial parts (flowers and leaves) from both species was analyzed by gas chromatography-mass spectrometry. Qualitative and quantitative differences were observed in the composition of the essential oil from both species. Oxygenated monoterpenes were the dominant compounds in the essential oil from both collections of T. terniflora where the main component was cis-tagetone (33.6% and 58.4% respectively) accompanied by significant amounts of the monotepene hydrocarbon cis-β-ocimene (17.1% and 17.4% respectively). cis-Tagetone (53.2%) was also a dominant component in T. minuta along with dihydrotagetone (10.4%) and cis-β-ocimene (19.9%). cis-and transocimenone were distinctive components of T. terniflora which were not detected in T. minuta. Anatomically stands out the presence of secretory cavities and glandular trichomes in foliar blades and secretory ducts in stems and petiole of both species.Key words: Tagetes terniflora, Tagetes minuta, essential oil, secretory tissues, morpho-anatomy.Resumen: Caracterización morfo-anatomía y aceites esenciales de Tagetes terniflora y Tagetes minuta (Asteraceae) de Tucumán (Argentina). Se estudió la composición del aceite esencial y morfo-anatomía de Tagetes minuta coleccionada en "El Mollar" y de dos poblaciones diferentes de Tagetes terniflora de Tafí del Valle (Tucumán, Argentina). El aceite esencial de las partes aéreas (flores y hojas) de ambas especies se analizó por cromatografía gaseosa-espectrometría de masa. Se observaron diferencias cuali-y cuantitativas en la composición del aceite esencial de ambas especies. En las dos colecciones de T. terniflora los compuestos dominantes del aceite esencial fueron monoterpenos oxigenados donde el componente principal fue la cis-tagetona (33.6% y 58.4% respectivamente) acompañado por cantidades significativas del hidrocarburo monoterpénico cis-β-ocimeno (17.1% y 17.4% respectivamente). La cistagetona (53.2%) fue también el componente dominante en T. minuta junto con dihidrotagetona (10.4%) y cis-β-ocimeno (19.9%). La cis-y trans-ocimenona fueron componentes característicos de T. terniflora que no fueron detectados en T. minuta. Anatómicamente se destaca la presencia de cavidades secretoras y tricomas glandulares secretores en los bordes foliares y conductos secretores en tallos y pecíolo de ambas especies.

-Pediculosis is a worldwide head infestation caused by Pediculus humanus capitis DeGeer. Resistance to chemical active ingredients shows the importance of new approaches for head lice control. The aim of the present work was to evaluate the potential insecticide activity of the medicinal plant Tagetes minuta (Asteraceae) against P. humanus capitis as well as to investigate histopathological aspects to find the target sites of the botanical extract in the insect. Lice were collected from heads of infested children 6-12 years old from Marília, São Paulo State, Brazil. All the procedures from the collection to the insecticide evaluation were done according to the World Health Organization protocols. Batches of 10 lice each were released onto a clean piece of filter paper in a petri dish. A 100 ppm concentration of essential oil impregnated filter papers were made by dropping 0.1 ml of T. minuta essential oil. Petri dishes were placed in a rearing chamber (30ºC and 70% relative humidity) in the dark. Eight replicates were used for treatment and two replicates for control batches. The Median Lethal Time (LT 50 ) was 16.4 ± 1.62 min. For histophatological investigation, twenty treated and untreated lice were fixed in 10% solution of formalin for 24h and processed according to classical histology techniques. Examined cross sections of treated adults showed disassembly of actin and myosin filaments arrangement when compared to untreated adults. This aspect allied to the LT 50 obtained suggests a toxic action of the T. minuta essential oil.KEY WORDS: Insecta, pediculosis, botanical extract RESUMO -De distribuição mundial, a pediculose é uma infestação na cabeça causada pelo piolho Pediculus humanus capitis De Geer. A resistência já verificada a diversos ingredientes ativos químicos demonstra a importância de serem avaliadas novas alternativas para o controle de piolhos. O objetivo do presente trabalho foi avaliar o potencial inseticida da planta medicinal Tagetes minuta (Asteraceae), conhecida como cravinho-de-defunto, contra P. humanus capitis, assim como investigar aspectos histopatológicos para se encontrarem os sítios de ação no inseto. Os piolhos foram coletados de crianças infestadas, de 6 a 12 anos de idade, no município de Marilia, SP. Todos os procedimentos desde a coleta até a avaliação da atividade inseticida foram feitos de acordo com os protocolos da Organização Mundial de Saúde. Grupos de 10 piolhos foram colocados sobre círculos de papel de filtro, no fundo de placas de Petri. Os círculos foram impregnados com o óleo essencial de T. minuta gotejando 0,1 ml de solução do extrato bruto obtendo-se a concentração de 100 ppm do extrato bruto. As placas foram colocadas em estufas de criação (30 ºC e 70% UR) no escuro. Oito repetições foram feitas para o tratamento e duas repetições para o controle. O tempo letal mediano para a concentração de 100 ppm do extrato bruto obtido foi de 16,4 ± 1,62 min. Para a investigação histológica, vinte piolhos tratados e não tratados foram fixados em formol 10% por 24h ...

The antifungal, antibacterial, and insect-repellent activities of the essential oils (EOs) of Acantholippia seriphioides, Artemisia mendozana, Gymnophyton polycephalum, Satureja parvifolia, Tagetes mendocina, and Lippia integrifolia, collected in the Central Andes area, province of San Juan, Argentina, were investigated. The dermatophytes Microsporum gypseum, Trichophyton mentagrophytes, and T. rubrum were inhibited by the EOs of G. polycephalum, L. integrifolia, and S. parvifolia, with minimum inhibitory concentrations (MICs) between 31.2 and 1000 μg/ml. Moreover, all EOs presented moderate activity against the bacteria tested, and the L. integrifolia and G. polycephalum EOs showed excellent repellent properties against Triatoma infestans, the Chagas disease vector, with repellency values between 60 and 100%. The A. seriphioides, G. polycephalum, and L. integrifolia EOs, obtained by hydrodistillation, were characterized by GC-FID and GC/MS analyses. The highest number of components (40) was identified in L. integrifolia EO, which, along with that of A. seriphioides, contained important amounts of oxygenated monoterpenes (44.35 and 29.72%, resp.). Thymol (27.61%) and carvacrol (13.24%) were the main components of A. seriphioides EO, and borneol, lippifoli-1(6)-en-5-one, and terpinen-4-ol (>8.5%) were the principal compounds of L. integrifolia EO. These results support the idea that oxygenated monoterpenes are the bioactive fractions of the EOs. Finally, the study shows that these Andean species might be used to treat superficial fungal infections and to improve the local Chagas disease situation by vector-control.
