More than 2000 cultivars of Phoenix dactylifera L. are known to grow around the world. Date is an essential fruit in North Africa, and in Libya in particular, it represents an important national food resource. Recently, researchers discovered the medicinal value of different parts of palm tree beside the well known nutritional value of the fruit edible part. In this study five Libyan date seeds (Bestian, Deglet, Abel, Khadrai and Hamrai) were collected from Aljofra region and were screened for phytochemical components and their antimicrobial activity. The phytochemical analysis of methanolic extract of five different Libyan date palm seeds showed the presence of aflavnoids, glycosides, phytosterols, phenolic compound, tannins, and fixed oil, absences of alkaloids and saponine. The susceptibility of bacterial species to five methanolic extracts of Phoenix dactylifera L seeds by cup-cut agar method exhibited Inhibition zones (IZD). That inhibition zone diameters are vary from 15.0 0.3 to 3.02 0.01 against MRSA; 16.040.1 to 6.0  0.7 against Pseudomonas aeruginosa; 14.2 0.1 to 6.00.7 against Proteus vulgaris; 18.3 0.2 to 6.0 0.1 against Staphylococcus aureus; 14.04 0.2 to 2.0 0.02 against E. coli; and 18.0 0.1 to3.2 0.02 against Klebsiella pneumonia. The results of current study shows the antibacterial properties of five Libyan samples of date seed extract against a wide spectrum of bacteria. arabic 21 English 126

Aims. The aim of this study was to assess the phytochemical screening and antibacterial effect of the aerial parts of G. alypum cultivated in Libya. Methods. The methanolic extract of G. alypum (at concentrations 100 mg/ml, 300 mg/ml, 500 mg/ml and 700 mg/ml) were tested against 13 different strains of standard bacteria (ATCC) by four different methods; paper disc diffusion method, well diffusion method, broth dilution method and finally study the effect of extract on growth curve of bacterial cell were studied. Results. The results of phytochemical screening revealed the presence of flavonoids, phenols, reducing sugars, tannins, saponins, coumarins, steroids, terpenoids, carotenoids, antraquinones and glycosides. While the results of antibacterial tests showed remarkable inhibition of the bacterial growth, with maximum inhibition on growth of Methicillin Resistant Staphylococcus aureus (MRSA) and Staphylococcus aureus. Moderate effect on growth of Enterococcus faecalis, Bacillus subtilis, Aeromonas hydrophila and Salmonella poona. While, the lowest inhibition showed in Yersinia enterocolitica and Listeria monocytogenes. However, the extract did not have any effect on Escherichia coli, Proteus mirabilis, Pseudomonas aeruginosa, Salmonella typhimurium and Klabsiella pneumonia. Conclusion. The methanolic extract of Globularia alypumaerial parts contain the most important constituents with positive results during phytochemical screening, and have antibacterial activity against gram positive and gram-negative bacteria.
