Macro- and micromorphology of the leaf, stem, stem bark and flower of Vangueria edulis cultivated in Egypt

Vangueria edulis belongs to Rubiaceae which includes about 620 genera with almost 13000 species which is widely distributed but mainly tropical. Biological studies showed that some species of the genus Vangueria showed antimicrobial activity, reported to have anthelmintic action and anti plasmodial activity and fed to cattle suffering from East Coast Fever. No detailed information could be traced concerning the macro- and micromorphology of the plant. This provoked the authors to carry out this study to identify the drug in both entire and powdered forms

Macro- and micromorphology of the leaf and stem of ruellia brittoniana leonard cultivated in Egypt

The genus Ruellia L. is sometimes called Dipteracanthus, it comprises about 150 species native to tropical and temperate North and South America. Ruellia brittoniana Leonard is known as Britton's wild petunia, wild petunia, Mexican bluebell and Ruellia tweediana Grisebach. Some species of genus Ruellia are used medicinally to cure gonorrhoea, syphilis, eye sores and in renal infections

new dimeric carbazole alkaloid from murraya exotic L [Rutaceae] cultivated in Egypt

In previous publications, the flavonoids, coumarins and cycloartenols, as well as three crystalline alkaloids; namely, koenoline, murrayacarine and koenimbine were isolated from Murraya exotica L. Further investigation of the oily fraction from carbontetrachloride extract of M. exotica L., revealed the presence of other two alkaloids as indicated from TLC technique. In a continuation of investigation of alkaloidal content of M. exotica L., the isolation and identification of these additional compounds; namely, bis-7- hydroxygirinimbine-A and bis-7-methoxygirinimbine, were presented

Alkaloids of Murray erotica L [Rutaceae] Cultivated in Egypt

Three alkaloids were isolated from the air-dried powdered leaves of Murraya exotica L. [Rutaceae], two of them; namely, murrayacarine and koeinoline were isolated for the first time from the plant, while the third alkaloid, koenimbine, was previously reported. The identification was based on physical, chemical and spectral studies including UV, IR, H-NMR and MS analyses
