Abstract The present research study was aimed to investigate the efficiency of selected medicinal plants against Plasmodium vivax. Crude methanolic extracts from seeds leaves Datura stramonium , Parthenium hysterophorus Calotropis procera and Dodonaea viscosa were prepared. In addition, Atropine also isolated alkaloid components Eucalyptus obliqua evaluate their in vitro anti-plasmodial effects...

Datura is one of the most interesting plants with hallucinogenic properties. Despite having a reputation as one of the 'darker' hallucinogens, it has been widely used by societies historically in both the Old World and the New, and continues to be today. For those interested in ethnobotanical uses of this plant world-wide, Datura is a fascinating topic. While being limited in its uses economica...

A 12 year old boy presented with an acute onset of anisocoria and blurred vision. Ocular motility was normal but his right pupil was dilated, round but sluggishly reactive to light. There was no history of trauma, eye drops' instillation, nebulised drugs or local ointments. His past medical history was negative.A third nerve palsy was considered but the performed cerebral MRI was normal.On furt...

Fifty three alkaloids were identified in the organs (roots, stems, leaves, flowers, and seeds) of Datura innoxia by GC/MS. Seventeen of them are reported for the first time for this species and one nor-derivative, 3-phenylacetoxynortropane (28), for the genus Datura. Furthermore, four new tropane esters were tentatively identified as 3-acetoxy-6,7-epoxytropane (acetylscopine) (10), 3-acetoxy-6-...

This study was designed to synthesize and evaluate derivatives of scopolamine (1) as acetylcholine esterase and protease inhibitors. Scopolamine (1) was extracted from the aerial parts of Datura innoxia through bioassay guided fractionation. Five different derivatives of scopolamine (1) were synthesized, and identified through spectroscopic studies. Their acetylcholine esterase (AChE) and tryps...

It is shown by tracer experiments with DL-[2-3H,5-14C]- and DL-[(RS)-5-3H,5-14C]rnithine, that the metabolic conversion of ornithine into proline, in three plant species (Nicotiana tabacum, Datura stramonium, and Lupinus angustifolius), takes place with maintenance of the delta-hydrogen atoms but with loss of the alpha-hydrogen atom. This indicates a route via alpha-keto-delta-aminovaleric acid...
