No full textThis study aimed to isolate some flavonoids from grapefruit leaves (Citrus paradise), and study their biological activity. The plant material was extracted by 95% ethanol . Removal of the solvent gave crude extracts .The extracts were subjected to a phytochemical screening which revealed the presence of flavonoids ,alkaloids ,terpenoids , tanins ,steroids , saponins .One compound of flavonoids was extracted from ethyl acetate fraction by thin layer chromatography (TLC) in a solvent system, butanol: acetic acid: distilled water (3:5:2). The isolated flavonoid was determined using UV tools. The UV maximum (max) was found at (283.50), which indicates the presence of flavanones in particular. The functional group was determined by infrared (IR) tool, where the functional groups were determined according to the wavelength of each of them: (344.63)OH, 1639.38 (C = O), 1566.09 (C = C, 1022.20 (C-O), 798.47 , and 671.18.cm-1 (C-H, Ar, curvature(. Which indicates the presence of a benzene ring. By using shift reaganents, more flavanone properties were identified. The antioxidant activity of the isolated compound was also examined using (DPPH) detection, and the results were (±78), which indicates the high activity of flavanones as an antioxidant. The antimicrobial activity of grapefruit leaf extract (Citrus paradise) was examined. Ethyl acetate extract was selected on pathogenic bacteria (Staphylococcus aureus). Ethyl acetate extract showed moderate antimicrobial activity against Staphylococcus aureus.In conclusion, the study proved that the leaves of the grapefruit plant contain flavonoids (flavanones), which are compounds that have antioxidant activity and are suitable for use as a rich source of antioxidants and microbes, especially for drug-resistant species. The grapefruit plant is economically viable and abundant in the country. The following is the approximate form of the isolated compoun

The research problem was that the traditional method used in teaching the Holy Quran subject for the deaf group class in the first grade is a basis that relies on recitation and memorization. Perhaps this study helps the class (deaf) in the first grade basis, to attract attention, excitement, assimilation and address individual differences in the teaching of the Holy Quran subject.
The hypotheses of the research have come to that the traditional teaching methods based on the efforts of the teacher, blackboard and textbook are not sufficient to achieve the goals in teaching the Holy Quran subject in the first grade as a basis for the deaf class. Designing a computer program in sign language has effectiveness in teaching the Holy Qur’an for the deaf class. The computer program in sign language To teach the Holy Qur’an material may help teachers achieve the goals. There are problems that prevent the design of a computer program in teaching the Holy Qur’an in sign language. The researcher used the experimental approach to suit this type of study, and the research reached a number of results uh Maha
Teaching The deaf people by designing the computer program makes the teacher's role positive.
The design of the computer program has an effective role in the delivery of information, the design of the computer program supports student achievement. One of the most important recommendations of the research is to provide libraries to design educational programs to benefit from in teaching the Holy Qur’an, work to provide a computer in schools or electronic information centers and sources, A chance to teach computer use for graduate student
