“…[26][27][28] Na literatura foram encontrados poucos trabalhos acerca do café conilon (ou robusta) cultivado no Brasil. [29][30][31][32][33][34][35][36][37][38][39] Nenhum deles trata dos compostos bioativos desta variedade produzida no estado do Espírito Santo. Em continuidade aos nossos estudos com cafés, [40][41][42][43][44][45][46] o presente trabalho teve como objetivo caracterizar os compostos bioativos (trigonelina, ácidos clorogênicos, ácido caféico e cafeína), determinar o teor de fenóis totais, teor de óleos essenciais e determinar a atividade antioxidante através da concentração eficiente (CE 50 ) em amostras de cafés da espécie Coffea canephora Pierre ex Froehner, cultivar conilon, em função do grau de torra (clara, média e escura).…”

The bioactive compounds and antioxidant activity presented by Conilon coffee (C. Canephora) variety, produced in the Espírito Santo State, Brazil, were quantified. The light roast coffee showed the highest level of total phenols, trigonelline, caffeic and chlorogenic acids. The proanthocyanidin level was the highest for dark roast coffee, while caffeine level didn't show significative changes for the light and middle roast coffees. All the Conilon coffee extracts showed antioxidant activity depending on bioactive compounds concentration and roasting degree. The coffee samples submitted to a light roasting degree showed the highest antioxidant activity.

Background: Endophytes are microorganisms which live within plant tissues without causing any apparent harm to their host. Endophytes have been found in nearly all plant families and can be a source of metabolites that are potential source of antibacterial drugs. Objectives: In this study, we focused on the isolation of bacterial endophytes from three medicinal plants; Zataria multiflora, Achillea willhelmsii and Calendula officinalis L. and screening them for activities against some human bacterial pathogens isolated from nosocomial infections. Methods: In this descriptive study random samples from asymptomatic leaves and branches of three medicinal plants namely: Zataria multiflora, Achillea willhelmsii and Calendula officinalis L. were collected from Chaharmahal Va Bakhtiari province of Iran in spring 2013. For isolation of endophytic bacteria, the disinfected portions of the plants were distributed onto the isolation media. To examine endophytic bacterial contents, the bioassays were conducted with using growing colonies in peptone agar (PA) and yeast extract agar (YEA) media, then inactivated them by chloroform. To assay antibacterial activity of endophytic bacterial culture broth, filter-sterilized supernatants were poured in cylinders on each bacterial plate. Results: Nine discernible bacterial endophytes were isolated in purification from three medicinal plants. Generally, all isolated endophytes showed acceptable effects against indicator bacteria, however endophytes isolated from Zataria multiflora and Achillea willhelmsii were more effective against Staphylococcus aureus than other endophytes. Conclusions: Endophytes of examined medicinal plants could be a good source of antibacterial substances.

“…In contrast, molecular techniques are sensitive and specific for indentifying microorganisms. They can be used for the taxonomic classification and identification of microbial strains (Sette et al, 2006). The internal transcribed spacer (ITS) has been used innumerous systematic studies at genus and species levels of a wide array of plant taxa (Alice andCampbell, 1999, Sang et al, 1995).…”

Plant-pathogenic fungi are a large and diverse group of organisms which exhibit great importance in agriculture and natural plant communities. In this study, we investigated the taxonomic identities and phylogenetic relationships of pathogenic fungi isolated from two medicinal Atractylodes macrocephala Koidz species, Swordlike A. macrocephala and Largehead A. macrocephala, using the morphological and molecular approaches. Morphological differences among the fungal isolates indicate that diverse distinct morphotypes might be present within the hosts. Forty fungal isolates were selected for further molecular phylogenetic analysis using the internal transcribed spaces (ITS1 and ITS2) of nuclear ribosomal DNA sequence and the intervening 5.8s gene region. While assessing diversity of Fusarium lateritium isolate and Gibberella zeae species from medicinal A. macrocephala using molecular approaches, Based on an 18S rRNA PCR approach, 4 fungal clone types were
