Inhibition of calcium oxalate monohydrate crystal growth using Algerian medicinal plants

A large number of people in this world are suffering from urinary stone problem. Calcium oxalate monohydrate (COM) and calcium oxalate dihydrate (COD) containing stones (calculi) are commonly found. In the present study, COM crystals were grown by artificial urine is prepared by mixing and stirring two equal volumes of solutions A and B. A screening of plant extracts from wild species antilithic agents using a urolithic...

In vitro antitrypanosomal activity of aqueous and methanolic crude extracts of stem bark of Ximenia americana on Trypanosoma congolense

The in vitro antitrypanosomal activity of methanolic and aqueous extracts of stem bark of Ximenia americana was evaluated on Trypanosoma congolense. Blood obtained from a highly infected mice with T. congolense (107) was incubated with methanolic and aqueous extract at 20, 10 and 5mg/ml and DiminalR (diminazene aceturate) at 200, 100 and 50 ug/ml in a 96 well micro titer plate. The results revealed that methanolic...

Antibacterial effects of S-(-)-tulipalin B isolated from Spiraea thunbergii Sieb. on Escherichia coli, a major food borne pathogenic microorganism

The crude ethanol extract of the leaves of Spiraea thunbergii Sieb. (Rosaceae) showed antibacterial activity against a food borne pathogen, Escherichia coli. Bioactivity-guided separation led to the isolation of a butyrolaton, 1(S-(-)-tulipalin B). The structure was determined from the interpretation of spectroscopic data (UV, MS, and NMR). The minimal inhibitory concentration (MIC) of compound 1...
