BACKGROUND Scrophularia striata (Scrophulariaceae family) is an herbaceous plant that is traditionally used for treatment of microbial infections. OBJECTIVES Antimicrobial and antioxidant activity of different extracts (methanolic, ethanolic, aqueous and ethyl acetate) from S. striata aerial parts was evaluated. MATERIALS AND METHODS The antimicrobial activity of different extracts from S. ...

Effect of different solvents; dimethyl-sulfoxide (DMSO), dimethyl formamide (DMF), methanol, tween 80 and acetone on morphology, cytology and reproduction of Aspergillus flavus, A. parasiticus, A. fumigatus and A. niger was assayed for standardization of a suitable organic solvent for test/antimicrobial compound in antimicrobial assays. Comparison of antimicrobial sensitivity methods was also m...

The paper focuses on the in vitro antimicrobial activity of Lavandula angustifolia Mill. (lavender) essential oil in combination with four commercial antimicrobial agents. Stock solutions of chloramphenicol, ciprofloxacin, nystatin, and fusidic acid were tested in combination with L. angustifolia essential oil. The antimicrobial activities of the combinations were investigated against the Gram-...

The antioxidant and antimicrobial properties of hot water extract (WE) obtained from Dictyophora indusiata were investigated. The free radical scavenging ability of WE on DPPH• was 97.35% at 2 mg/ml concentration. The reducing power of WE was moderate (1.22 at 2 mg/ml). Similarly, the WE displayed average scavenging effect on hydroxyl radical (52.28% at 2 mg/ml) and superoxide anion scavenging ...

A rapid and high yield microwave assisted synthesis of a series novel 7,9-bis-(arylidene)-4-methyl-2,6,10-triphenyl-2,3-diazaspiro[4,5]dec-3- -ene-1,8-dione has been explored. The spiro diarylidene derivatives having nitrogen atom ?,?-unsaturated ketone moiety were synthesized by aldol condensation between 4-methyl-2,6,10-triphenyl-2,3-diazaspiro[4,5]dec-3-ene-1,8- -dione corresponding aryl ald...

BACKGROUND Genital mycoplasmas colonise up to 80% of sexually mature women and may invade the amniotic cavity during pregnancy and cause complications. Tetracyclines and fluoroquinolones are contraindicated in pregnancy and erythromycin is often used to treat patients. However, increasing resistance to common antimicrobial agents is widely reported. The purpose of this study was to investigate ...

The present study aims to investigate the in vitro antibacterial activities of several isophosphinoline-2-oxides that can be perceived as combined bio isosteres coumarins and flavonoids. More specifically, activity was evaluated against four bacterial strains, including Gram-negative bacteria Escherichia coli Pseudomonas aeruginosa Gram-positive Staphylococcus aureus Enterococcus faecalis by us...

In the present study deals with the antimicrobial properties of the Andrographis neesiana were tested against five human bacterial pathogens by using five various solvent namely, ethanol, methanol, acetone, chloroform and petroleum ether. The maximum antimicrobial activity was noted in petroleum ether extracts of stem showed activity against Escherichia coli (16mm) and the minimum was recorded ...
