In Vitro Organogenesis in Rumex Thyrsiflorus Fingerh. – Problems of Sex Ratios

Rumex thyrsiflorus Fingerh. is one of the few dioecious plant species, which have sex chromosomes. We conducted the preliminary experiments to determine the type of morphogenesis of R. thyrsiflorus explants cultured in vitro and to verify, using PCR-based methods, if there is the relationship between sex and morphogenetic response of explants micropropagated under in vitro conditions. The resul...

Lipophilic Constituents of Rumex vesicarius L. and Rumex dentatus L.

Rumex dentatus L. and Rumex vesicarius L., of the family Polygonaceae, are edible herbs growing wild in Egypt. Their lipoid constituents were examined by both liquid chromatography/mass spectrometry (LC/MS) and by gas chromatography/mass spectrometry (GC/MS). Their essential oil compositions consisted mainly of thujene, limonene, fenchon, estragole, and anethole but at largely different concent...

Evaluation of Anthelmintic Activities of Rumex Abyssinicus Jacq and Rumex

Helminthiasis is a disease in which a part of the body is infested with worms such as pinworm, roundworm or tapeworm. Typically, the worms reside in the gastrointestinal tract but may also burrow into the liver and other organs. Rumex abyssinicus Jacq and Rumex nervosus Vahl (polygonaceae) is a large annual herb up to 4m high, leaves usually sagittate, inflorescence much branched, leafless pani...

Antimicrobial Activity of Cassia didymobotrya and Phlogacanthus thyrsiflorus

The in vitro antimicrobial activity of Cassia didymobotrya and Phlogacanthus thyrsiflorus leaf extracts were studied against selected bacteria and fungi following Agar disc diffusion method. Leaves were extracted using distilled water, methanol and ethyl acetate. Three different concentrations were applied to the disc (100μg, 250μg and 500μg/disc) for each extracts. While the aqueous extracts o...
