Evaluation of combinatory effects of Anadenanthera colubrina, Libidibia ferrea and Pityrocarpa moniliformis fruits extracts and erythromycin against Staphylococcus aureus
Anadenanthera colubrina, Libidibia ferrea and Pityrocarpa moniliformis are widely used in Caatinga and our group has demonstrated their biotechnology potential. This work evaluated the combined action of erythromycin with extracts obtained from fruits of A. colubrina(ACHE), L. ferrea (LFHE) and P. moniliformis (PMHE) against Staphylococcus aureus. The...

Assessment of mineral substances level and antioxidant potential in leaves of three guava tree varieties
Guava tree leaves are used empirically for the treatment and prevention of several pathologies, however, few studies report the chemical composition and the biological activity of the species. In this context, this study was conducted with the objective of evaluating the chemical composition and the antioxidant activity of the leaves of Paluma, Pedro Sato and Século XXI cultivars. The leaves were oven dried at...

Molecular mechanisms that underlie the sexual stimulant actions of ginger (Zingiber officinale Rosocoe) and garden rocket (Eruca sativa L.)
The effects of extracts and subfractions of Zingiber officinale rhizomes, Eruca sativa seeds and sildenafil on the sexual behavior of male rats and their effects on the intracavernosal pressure (ICV), intracavernosal cyclic cyclic guanosine monophosphate (GMP) and dihydrotestosterone plasma level were examined. The sexual behavior was followed for four hours using infra-red video cameras to...

Variability and genetic diversity assessment in physic nut (Jatropha curcas L.)
A trial was conducted to assess genetic parameters and diversity in physic nut (Jatropha curcasL.). Data were collected on ten biometric traits during year 2007 to 2008 and 2008 to 2009.Genotype Indira Gandhi Agricultural University (IGAU)-Raipur ranked first for seed yield (0.269, 0.492 kg/plant) in year 2007 to 2008 and 2008 to 2009, respectively. In 2007 to 2008, dry fruit yield/plant accounted...

Application of Cymbopogon winterianus Jowitt and Azadirachta indica A. Juss in the control of Rhipicephalus (Boophilus) microplus
Parasitism is one of the main problems that affect livestock. Commercial acaricides have been used in order to control tick, but these chemicals have been responsible for the development of drug resistance and residues in the environment. Changes in the concept of production determined the search for natural measures, which guarantees animal sanity along with safety of the produced food. This essay had as an objective,...

Crude extracts and semi-fractions from Myracrodruon urundeuva with antibacterial activity against American type culture collection (ATCC) strains of clinical relevance
The objective of this study was to investigate the antibacterial activity of crude and semi-pure extracts obtained from Myracrodruon urundeuva (Aroeira do sertão) against clinically important ATCC bacterial strains by preparative thin layer chromatography (TLC). The results indicate potential activity as assessed by minimal inhibitory concentration (MIC) and minimum bactericidal concentration (MBC)...

Chemical composition and biological activities of essential oils and solvent extracts of Origanum vulgare subsp. glandulosum Desf. from Tunisia
This study aimed to quantify the active biological compounds in Origanum vulgare subsp.glandulosum Desf. Analysis of the chemical composition essential oil from Tunisia was carried out using gas chromatography-mass spectral (GC-MS). The antioxidant capacities of essential oil and extracts were evaluated using free radical scavenging, ferric reducing antioxidant power assay and metal chelating effects. The...
