The 10% ethanol extract of the aerial parts of Calligonum comosum (50--400 mg/kg, i.p.) significantly reduced the increase in hind paw oedema induced by carrageenan in rats. Following sub-acute oral administration of the extract (50 and 100 mg/kg, daily for 14 days), a significant anti-inflammatory activity in the cotton pellet model was observed. Pre-treatment with the extract (100, 200 and 40...

Calligonum comosum, a Tunisian plant from arid regions, is traditionally used in folk medicine to treat rural population microbial infections. The plant was investigated in vitro for its ability to inhibit the growth of Listeria ivanovii. Various aqueous and organic extracts were prepared from different plant tissues. Results indicated that ethanolic, methanolic and acetonic extracts from whole...

Calligonum comosum (Polygonaceae), an Egyptian desert plant, was extracted and fractionated using petroleum ether, methylene chloride, and ethyl acetate. The total methanolic extract and other fractions were tested for their anticancer activity using Ehrlich ascites, brine shrimp and antioxidant assays. Ethyl acetate fraction proved to be the most active in all assays. Eight compounds were isol...

Due to drought, low soil fertility, little rain fall, elevated levels of evapotranspiration, salinization the and a lack ground water, problem desertion agricultural areas has developed in KSA recent years (e.g. Tabuk region). In Saudi Arabia, land abandonment’s negative impact on composition perennial vegetation, quality, structure population was investigated. several abandoned fields research...
