background and objectives: several natural compounds have been identified for the treatment ofleishmaniasis. due to a few safe drugs and the side effects caused by available chemotherapy, some new drugs for treatment of leishmaniasis are requested.  the genus pulicaria (asteraceae) is represented in the flora of iran by five species. phytochemical studies on pulicaria species have revealed some...

This study aimed to analyse the antibacterial potential of limonene, terpineol, and eugenol for biofilm reduction food-borne E. coli, S. aureus typhimurium. A microdilution test with resazurin application was used minimum inhibitory concentration a colony plate count bactericidal concentration. Biofilm biomass quantified using crystal violet assay, while viability determined method. The results...

background & aim: myrtle (myrtus communis l.), is an important medicinal plant that is used for pharmacological uses and conservation of environments (for example preventing the soil erosion) regards to its specific condition habitat.experimental: in this research, phytochemical variations of the essential oils from different populations of myrtle collected from fars (saydan, cheshme-ali, a...

In this study, tarragon (Artemisia dracunculus L.) the amount of antioxidants and phenolic substances water-based extracts in various concentrations (25g/L, 50g/L, 100g/L) with aroma components plant was determined. Various food pathogens (Escherichia coli ATCC 25922, Salmonella enterica 13076, Listeria monocytogenes 43251) bacterial strains ((Gram-negative (Vibrio harveyi (KF443058), Vibrio vu...

Gas chromatography-olfactometry-mass spectrometry (GC-O-MS) has been very useful in identifying aroma compounds from within the complex matrix of wine. Supplementary separation can be required to overcome co-elution volatiles or other sensory-directed chromatographic strategies are needed, including multidimensional chromatography and preparative fraction collection coupled GC. Studies investig...

The perovskite film is the core of a solar cell (PSC), and its quality crucial for performance such devices. morphology, crystallinity, surface coverage layer greatly affect power conversion efficiency (PCE), hysteresis, long-term stability PSCs. incorporation appropriate solvent additives in precursor solution an effective strategy to control morphology reduce defects grain boundaries. However...

Bay laurel leaves, also known as bay are an important herb in many cuisines around the world. In addition to their use cooking, leaves have been used for medicinal properties and thought anti-inflammatory antimicrobial effects. Gas chromatography/mass spectrometry (GC-MS) device was determine secondary metabolites essential oil of samples kept at different temperatures (−22, −20, −18, 2, 4, 6, ...

The harvest time of grapes is a major determinant berry composition and the wine quality, it usually established through empirical testing main biochemical parameters berry. In this work, we studied how ripening stage Aglianico modulates key secondary metabolites wines, phenolics volatile compounds. Specifically, analyzed compared four stages corresponding to total soluble solids 18, 20, 22, 25...
