Ninety solvent extracts (n-hexane, dichloromethane and methanol) obtained from the leaves, bark and stem of 13 Sri Lankan Rubiaceae and two Sri Lankan Meliaceae plants have been screened for antibacterial and antifungal activities. Morinda tinctoria, Mussaenda frondosa, Psychotria gardneri and Psychotria stenophylla displayed the widest spectrum of antibacterial activity.

introduction: chitosan possesses more than 5000 glucossamine residue. since chitosan possesses potentially reactive amino functional groups, this polymer has been shown to be of potential use in many different fields, including as an antifungal compound in agriculture, flocculating in waste water treatment, a food additive and alimentary industries, hydrating agent in cosmetics and more recentl...

We have investigated the antibacterial, antifungal and cytotoxic activities of two flavonoids isolated from Retama raetam flowers using the disc diffusion and micro-dilution broth methods. The cytotoxic activity was tested against Hep-2 cells using the MTT assay. The compounds licoflavone C (1) and derrone (2) were active against Pseudomonas aeruginosa and Escherichia coli (7.81-15.62 μg/mL) an...

Objectives: This work aims to analyze the antibacterial and antifungal activities of cruciferous vegetables such as cauliflower broccoli. Methods: Cruciferous act a good source natural antioxidants due their high levels carotenoids, tocopherols, ascorbic acid. In this study, two vegetables, broccoli, were selected for anti-fungal studies. The stems, flowers cauliflower, broccoli extracted with ...

reaction of 5-phenyl tetrazole with ethyl chloroacetate to form ethyl (5-phenyl-1h-tetrazol-1-yl) acetate (1). compound 1 react with hydrazine hydrate in ethanol yield 2-(5-phenyl-1h-tetrazol-1-yl) acetohydrazide (2). the condensation of (2) with various aldehydes yield the corresponding substituted n'-[-arylidene]-2-(5-phenyl-1h-tetrazol-1-yl) acetohydrazide (3a- j). the compounds obtaine...

We investigated the inhibitory effects of antibacterial, biocidal, and antifungal agents against Fusarium spp. Seven Fusarium spp: four F. falciforme (Fusarium solani species complex), one Fusarium spp, one Fusarium spp. (Fusarium incarnatum-equiseti species complex), and one F. napiforme (Gibberella fujikuroi species complex), isolated from eyes with fungal keratitis were used in this study. T...

A series of 1,4-dihydropyrimidine derivatives 3(a-t) were prepared from Biginelli reactions by using ethyl acetoacetate, substituted benzaldehyde and thiourea in the presence of piperidine and ethanol. The compounds 3(a-t) were reacted with dimethylsulphate, diethylsulphate, butyl bromide and benzyl chloride to give the new series of compounds 4(a-t). The structures of the newly synthesized com...
