Abstract: The plants are one of the most important drugs of sources. For example, (sweet basil) is one of these plant tribes that symbolize all that is extraordinary in nature, because the entire plant has been used by traditional medicine for the treatment of the family against various human diseases of antiquity. The aim of this paper is to review the literature on basil; samples were collected from different farms of Khartoum state, specifically the oil that is extracted by cold extraction with water and effectiveness against bacteria and toxicity and effectiveness against oxidative stress and therapeutic benefits studied scientifically. This review consists of all relevant basil that has been identified by researchers through the systematic research of major medical computerized data base publications. Our Study indicate that own basil analgesic, anti-inflammatory, antimicrobial, antioxidant, and the activities of the larvae, uses in medicine Traditional and tonic and repellent mosquito and in this research were prepared cream repellent mosquito formula and proven experience success and effectiveness of this very great benefit if it reduces the incidence of malaria and protect against mosquito bites people. These results are very encouraging and indicate that this cream should be taught more widely to confirm these results and to find other Potential therapeutic effects were achieved the goals set in the research.

Abstract: Chance fermentation is a biochemical process of transformation and conservation during which degradation of organic molecules (proteins and lipids) occurs through the action of enzymes. Some methods often used to determine degradation products of organic molecules are expensive, slow, inefficient and even critical. But the knowledge of certain physicochemical parameters can lead us to estimate the chemical modifications that occurred during the transformation of a foodstuff. This is how conductimetry, pH-metry and refractometry are used to make an express assessment of the fermentation of Scomberomorus tritor. The biological degradation phenomena of organic molecules being identical at the level of the hydrolyzate as whole fish, the hydrolyzate of Scomberomorus tritor is subjected to a spontaneous fermentation during 72 hours and, evolutions of the electrical conductivity, the index refraction and pH are recorded. The obtained results show the electrical conductivity variations between 1200μS and 8900μS, the one of the pH between 6.8 and 6.3 and the one of the refractive index between 1.331 and 1.333 during the fermentation of Scomberomorus tritor. These variations are due to the appearance of suspended degradation products (ionized bodies), proof that there has been fermentation. The instrumental methods used allowed us to make an express assessment of the fermentation of Scomberomorus tritor. These methods are sensitive, fast, effective and do not need chemical reagents.

Abstract: A Schiff base (SB) is derived from salicylaldehyde and 2-aminopyridine. The transition metal complexes of N i(II), Cu (II), Co and Cd (II) metal ions were prepared with this Schiff base (SB), which were used as ligand. Several physical tools, in particular; elemental analysis, molar conductivity, magnetic susceptibility, infrared spectroscopy (IR), electronic absorption spectroscopy (ESR) to investigate the chemical structure of the prepared transition metal complexes. The elemental analysis data shows the formation of 1:2 [M:2L] complex of the formula of M2+L2, where M2+ =Ni(II), Cu(II), Co(II), Cd(II) and L = Schiff base (SB). The molar conductance (conductivity) measurements were revealed that all the complexes are non-electrolyte in nature. The infrared (IR) spectral studies indicated the binding sites of the Schiff base ligand with the transition metal ions. The magnetic susceptibility measurements and electronic spectral results supported the predicted coordination geometry of the complexes and magnetic properties (para or dia-magnetic nature) of the complexes. The Ni(II), Cu(II), Co(II) ion forms high spin tetrahedral geometry, whereas Cd(II) ion forms low spin tetrahedral structure. The free Schiff base and its complexes have been tested for their antimicrobial activities against four human pathogenic (two gram-positive and two gram-negative) bacteria. The obtained results showed that only Cu(II) complex exhibited strong activity toward human pathogenic gram positive and gram negative bacteria whereas the Ni(II), Co(II) and Cd(II) complexes showed week to moderate antimicrobial activity compared with standard Kanamycin and Ampicillin.
