plants produce a diverse array of secondary metabolites, many of which have antimicrobial activity. otostegia persica bioss. (labiatae) grows in south east of iran. no previous investigation on antimicrobial effects of this plant has been reported. thus, the aim of this work was to examine the antimicrobial effect of o. persica extracts with different polarity on several microorganisms. aerial ...

Ferulago W. Koch. (Apiaceae) genus is represented by approximately 50 taxa throughout the world. Ferulago species are known as "Çakşır" or "Çağşır" in Turkey and mostly known for their aphrodisiac effects. However recent reports emphasize the activity of various Ferulago species against cancer, as well. The aim of this study was to investigate the effect of lyophilized extract of F. mughlea Peş...

Materials and Methods Thirty-six extracts obtained from differ...

As an attempt to search for bioactive natural products exerting antiinflammatory activity, we have evaluated the effects of the methanol extract from the aerial parts of Saururus chinensis (LOUR.) BAILL (Saururaceae) on lipopolysaccharide (LPS)-induced nitric oxide (NO) and prostaglandin E(2) (PGE(2)) release by the macrophage cell line RAW 264.7. Our data indicate that this extract is a potent...

PURPOSE This study describes the antibacterial effect of extracts and compounds isolated from the aerial part of Chelidonium majus Linn. (Papaveraceae) acting against clinical strains of methicillin-resistant Staphylococcus aureus (MRSA). METHODS The activities were evaluated by using the macrobroth dilution method and reported as the MICs/MBCs. RESULTS Bioassay-guided fractionation of the ...

An investigation, on the roots of Piper nigrum and the aerial parts of Piper betle, has yielded several alkaloids. The dried root sample of Piper nigrum was extracted using various solvents in increasing polarity. The dried aerial part of Piper betle was extracted using the Soxhlet extraction method. The alkaloids isolated were pellitorine(1), (E)-1-[3’,4’(Methylenedioxy)cinnamoyl]piperidine(2)...

The extraction of road networks from aerial images is one of the current challenges in digital photogrammetry and computer vision. In this paper, we present our system for 3D road network reconstruction from aerial images using knowledge-based image analysis. In contrast to other approaches, the developed system integrates knowledge processing of color image data and information from digital sp...
