Biodiversity and prevalence of chewing lice on local poultry

Biodiversity and prevalence of chewing lice on local poultry (Gallus Gallus Domesticus, family Phasianidae) have been successfully determined for five selected sites around Qaser Bin Ghashir region, Libya between November 2017 and April 2018. The total investigated chicken samples are 135, and the infected samples were found to be 94. Ticks, fleas, and mites were detected in a small quantity in addition to three different species of biting lice. The obtained results show that Asuani has the lowest amount of ectoparasites, while Suq AL-kamees samples were infected completely by 100 % prevalence of chewing lice. The calculated total average prevalence percentage (TAP, %) of all sites are ≤70%. Three species of lice were detected and identified on the local poultry, Menopon gallinae, Menacanthus stramineus and Lipeurus caponis. The most abundant species in the study area is Menopon gallinae with prevalence percentage about ≈ 69.84%. A comparison between chewing lice around Qaser Bin Ghashir region in Libya and other countries has been carried out and it was found that (TAP, %) for Algeria > (TAP, %) for Libya > (TAP, %) for USA. Finally, the study proves that Libya contains a mild status of biodiversity.

A review on saponins from medicinal plants: chemistry, isolation, and determination

Saponin isolated from medicinal plants is a naturally occurring bioorganic molecule with high molecular weight and its aglycone (water non-soluble part) nucleus having 27 to 30 carbon atoms besides one or two sugar moieties (water soluble part) containing at least 6 or 12 carbon atoms respectively. The complexity of saponin chemistry maybe considered as a gap for many scientists and researchers to understand the relationship between the chemical structure and its medical or pharmaceutical behavior. Recently, the increase in demand of saponin applications was observed due to various biological, medicinal, and pharmaceutical actions. Therefore, this present review article provides detailed information about the chemistry of saponin, especially triterpenoid saponin. Classifications, chemical structure, the possible traditional isolation ways, qualitative, and quantitative determination of saponins were included exclusively. Examples of mono and bidesmosidic structure of oleanolic acid and hederagenin also outlined. Structural differences between triterpenoid, steroid, and alkaloid glycosides were summarized according to their atoms, rings, and functional groups.

Chemical and Technical Investigations on Soil Characterization and Silicic Acid Preparation

Physicochemical Characteristics of three soil samples collected from Qaser Bin Ghashir region, south of Tripoli, Libya have been investigated in terms of soil permeability, density (ρ), water content (WC), organic content (OC), dissolved salts content (DS), and inorganic ash content (IAC) as-well-as the reaction towards mineral acids and bases. Silicic acid Si(OH)4 was successfully prepared from a sandy soil sample in a considerable amount and the mechanistic equations were proposed for three possible preparation routes of the acid. Results show that the sandy sample is the most permeable and reliable soil for the water penetration and silicic acid preparation respectively. Values of pH and the reaction between soil samples and mineral acids prove the alkalinity nature of the samples. Chemical composition of the investigated samples were determined and were found to vary from the sample to another and from content to other according to the origin and nature of the soil.
