Erythrina mulungu Benth. (Fabaceae), Cordia verbenacea A. DC. (Boraginaceae), Solanum paniculatum L. (Solanaceae) and Lippia sidoides Cham. (Verbenaceae) are medicinal plant species native to Brazil shortlisted by the Brazilian National Health System for future clinical use. However, nothing is known about their effects in metabolic and transporter proteins, which could potentially lead to herb...

Geraniaceae plastid genomes are highly rearranged, and each of the four genera already sequenced in the family has a distinct genome organization. This study reports plastid genome sequences of six additional species, Francoa sonchifolia, Melianthus villosus, and Viviania marifolia from Geraniales, and Pelargonium alternans, California macrophylla, and Hypseocharis bilobata from Geraniaceae. Th...

Plant-derived pharmaceuticals have become prominent in the market place, making it a favored healthcare choice. In this study, air dried samples of aerial parts of Pelargonium X fragrans Willd. and Pelargonium peltatum L’Hérit. were separately extracted using successive extraction with a soxhlet apparatus. Each extract was tested for its antimicrobial activity using two Gram-negative bacterial ...

Pelargonium species have various uses in folk medicine as traditional remedies, and several of them have been screened for their biological activity, including anticancer. Pelargonium quercetorum Agnew (P. quercetorum) is traditionally used for its anthelminthic activity. However, little is known about its biological activity or its effect on cancer cells. The aim of the present study was to de...

background: nanosilver particles are among the potentially candidates for modulating the redox status and changing the growth, performance and quality of plants because of their physicochemical characteristics.   objective: this study was carried out to elucidate the potential effects of nanosilver particles application on variations of photosynthetic pigments (chlorophyll and carotenoids) and ...

background staphylococcus aureus is one of the most causative organisms in the skin wound infections. development of resistant s. aureus to current treatments in individuals with low immunity is a global concern. the aim of this study was to evaluate the efficacy of herbal formulation against skin wound infection. methods the efficacy of herbal formulation containing oliveria decumbens and pela...

Premise In semiarid regions, decreasing rainfall presents a challenge to perennial seedlings that must reach sufficient size survive the first year’s seasonal drought. Attaining large storage organ has been hypothesized enhance drought resilience in geophytes, but building larger organs requires faster growth, paradoxically, some traits confer growth are highly sensitive We examined whether tub...

This paper presents a new application of the normal mode decomposition to measure the reflection and absorption coefficients of a low growing living plant in a large 300 300 mm impedance tube. In this way the higher frequency limit can be extended by a factor of 3 in comparison to that suggested by the standard ISO 10534-2 method for this type of an impedance tube. The adopted method (Prisutova...

Ag thin films were successfully produced via a green chemistry method from silver nanoparticles (AgNPs) obtained reacting an extract of Pelargonium Zonale leaves with nitrate. The ions nitrate reduced to atoms by reducing stabilizer-capping compounds contained in the leaves. nucleate small clusters that grew into and finally, they formed homogeneous film on glass substrate. nanostructured chara...

The increased incidence of visceral leishmaniasis (VL) in Brazil is due to a lack of effective disease control measures. In addition to that, no effective treatment exists for canine VL in response to synthetic drugs. Thus, the objective of this study was to evaluate the effect of the essential oils of Coriandrum sativum and Lippia sidoides, and oleoresin from Copaifera reticulata, on Leishmani...
