Evaluation of the blood pressure lowering activity of leaf extract of Acalypha torta Muell
The leaf of Acalypha torta Muell. (Euphorbiaceae) is used as folk remedy in Nigeria for the treatment of hypertension. Effects of extracts of A. torta leaf on the blood pressure of anaesthetized cats were studied to examine this claim. The ethanol extract produced a significant (p < 0.0001) and dose - dependent fall in arterial blood pressure. The extract inhibited adrenaline - induced contraction...

Investigation of fatty acid composition of Ammi visnaga seed oil by gas chromatography-mass spectrometry (GC-MS)
The Ammi visnaga seeds oil constituents of methyl ester derivatives of fatty acids were analyzed using gas chromatography coupled with mass spectrometer. The results obtained contain saturated as well as unsaturated fatty acids of A. visnaga seeds oils. A total of 15 different components were identified and quantified. Methyl ester of oleic acid was found in high concentration (13.30%) among the identified analytes of...
