Cytotoxicity of alkaloids isolated from Peganum harmala seeds.
ETHNOPHARMACOLOGICAL RELEVANCE Peganum harmala is used in traditional medicine to treat a number of diseases including cancer. Our preliminary studies show that the alkaloidal extract of PH seed is cytotoxic to several tumor cell lines in vitro and has antitumor effect in a tumor model in vivo. The present investigation was aimed at extending our previous studies in identifying the components i...
متن کاملOptimization of Continuous Flow Adsorption of Heavy Metal Ions on Continuous System Column by Peganum Harmala Seeds
Background & Aims of the Study: Heavy metals discharge to environment is a worldwide problem growing in scale. When they accumulate in the environment and in food chains, they can profoundly disrupt biological processes. Peganum Harmala Seeds (PHS) was used as a bio-sorbent, using a continuous system for removing Pb2+, Co2+, Ni2+ and Cu2+ ions from aqueous solutions. ...
متن کاملAdsorption of copper, cadmium, lead and zinc onto a synthetic manganese oxide.
Due to its simple and inexpensive synthesis, a new amorphous hydrous manganese oxide (AMO) has been studied as a possible chemical stabilizing agent for soils contaminated with metals. Preliminary experiments evaluating the stability of AMO in pure water have reported only minor dissolution (5.70% and 0.24% depending on the w/v ratio). Sorption kinetics have shown fast metal adsorption, especia...
متن کاملAdsorption of cadmium ions from aqueous solutions using sesame as a low-cost biosorbent: kinetics and equilibrium studies
Sesame leaf and stem, as a kind of useless agricultural waste, was used as a sort of low-cost biosorbent for the removal of cadmium ions from aqueous solutions in batch and continuous modes. The biomass was characterized by Fourier transform infrared spectroscopy, scanning electron microscope and energy-dispersive X-ray analysis before and after adsorption. There were hydroxyl group, carboxyl g...
متن کاملVasorelaxant effects of harmine and harmaline extracted from Peganum harmala L. seeds in isolated rat aorta.
The present work describes the mechanisms involved in the vasorelaxant effect of harmine and harmaline. These alkaloids induce in a dose-dependent manner the relaxation in the aorta precontracted with noradrenaline or KCl. However, the removal of endothelium or pre-treatment of intact aortic ring with L-NAME (inhibitor of NOSe synthetase) or with indomethacin (non-specific inhibitor of cyclo-ox...
