The present work aims to study the potential effect of jamun Syzygium cumini seeds and leaves to give more protection against hyperlipidemia . Twenty male albino rats were used over 30 days period. The animals were divided into (4) groups, wherein groups number (1) represent control which were fed basal diet, while group number (2) was received high fat diet to serve as hyperlipidemic group. Other two groups allowed to feed high fat diet supplemented with jamun seeds and leaves, group number (3) treated simultaneously with jamun seeds, fourth group treated with jamun leaves. At the end of the experimental period, blood samples were collected to determine lipid profile, liver functions and determine the kidney functions include urea nitrogen and creatinine. From the obtained results we concluded that group of rats fed on high fat diet were considered as a major risk factor for hyperlipidemia disease. Our results could be summarized that jamun seeds and jamun leaves were considered the best for causing a reduction of TC, TG and LDL. Also, liver functions has been improved and there were significant reduction GOT, GPT and ALP activity than that of positive control group. It could be concluded that jamun seeds and jamun leaves under study are useful for the treatment of hyperlipidemia.

The objective of research was to study the chemical composition , phenolic compounds and flavonoids of powder from anise seeds and mint leaves. Anise seeds contains: total carbohydrates 51.4 %, crude protein 18.1 %, total lipids 13.7 % and total ash 14.9 % in dry sample. While mint leaves contains contains total carbohydrates 55.7 %, crude protein 19.8 %, total lipids 4.9 %, and total ash 18.6 % in dry sample. Total phenolic in anise seeds were 216.6-237.8 mg/100g in aqueous and ethanolic extracts, respectively and total flavonoids were 148.1-156.4 mg/100g in aqueous and ethanolic extracts, respectively comparing with 234.3-278.9 mg/100g in aqueous and ethanolic extracts, respectively and 157.5-186.3 mg/100g in aqueous and ethanolic extracts, respectively of total phenolic compounds and flavonoids in mint leaves. HPLC results showed that anise seeds were found to contain 19 of phenolic compounds, amoung them catechein, cinnamic, ellagic, gallic, chlorogenic, ferulic and catechol were the major active in anise seeds, while mint leaves contained rosmaric, cinnamic, gallic, ferulic, and savianolic as the major of phenolic compounds. In conclusion the obtained results found that, anise seeds and mint leaves extracts were rich in secondary metabolites (phenolic compounds and flavonoids) with high nutritional and health values.

The objective of research was to study chemical composition, phenolic compounds and flavonoids of powderd from anise seeds and mint leaves. Anise seeds contain total carbohydrates 51.4 % , crude protein18.1 % , total lipids 13.7 % and total ash 14.9 % in the dry sample. While mint leaves contain carbohydrate 55 % , crude protein, total lipids 4.9 % and total ash 18.6 % in the dry sample .Total phenols in anise seeds were 237.8 and 216.6 mg / 100g , while total phenols in mint leaves were 278.9 and 234.3 mg / 100g in ethanolic and water extracts respectively. The total flavonoids in the anise seeds were 156.4 and 148.1 compared with the total flavonoids in mint leaves were 186.3 and 157.5 in ethanolic and water extracts respectively. HPLC results showed that anise seeds were contained 20 phenolic compounds, representing oleic acid, alkaline acid, cinnamic acid and catechein. The main active ingredients compared to 22 phenolic compounds were mint leaves containing Gallic, Gallic, Ferulic, and Rosmarinic That the main of phenolic compounds.

Accordingly, this study was planned to investigate the effect of cold water and alcoholic extracts of Trigonellafoenum(fenugreek) and Lupinusluteus (yellow lupine) on the biological attributes and biochemical responses of the 4th instar larvae of Spodoptera littoralis (thecotton leafworm).
The main objective of this study is to investigate the possibility of using plant extracts as insecticides to control the cotton leafworm.
Thus, in our study a recommended pesticide namely chlorpyrifos (dursban) was used as a reference to compare its effect on some biological and biochemical aspects of the 4th instar larvae of the cotton leafwormwith those obtained from water and alcoholic extracts of fenugreek and yellow lupine.
Results indicated that both water and alcoholic extracts of fenugreek and yellow lupine were effective against the cotton leafworm, especially at the concentration of 10%; while fenugreekextract was the most effective agent as it affects larval, pupal and adult stages of the tested insect. It also reduce protein level, alkaline and acid phosphatases levels.
Thus we can conclude that extracts of fenugreek and yellow lupine can be used as a good insecticide against cotton leafworm.

Four different fruits peels (Banana, Watermelon, Orange and Mango) were chosen to study the possibility to produce biofuel. The starch, pectin, hemicellulose, celluloses, lignin and proteins fractions were determined in terms of dry weights percentages for these peels.
The obtained results showed that mango peels recorded the highest oligosaccharides levels, even lignin content was highest by 17.25%. Also, banana peels showed high oligosaccharides levels, with the lowest level of lignin by 4.82%.
Aspergillus niger and Phanerochaete chrysosporium were used to degrade fruit peels , where during their degrading enzyme assays the co-cultivation can improve extracellular enzyme secretion. While, the co-cultivation was resulted an increasing in enzymes activities by 5.8, 8.8 and 81.3 nmol.min-1.ml-1 for β-glucosidase, celulase and xylanase, respectively.
The SDS-PAGE protein profiles confirmed that, fungi co-cultivation results in improved the excretion of relevant enzymes proteins, the combined profile were contained proteins not observed in the individual fungus culture.
The banana and mango peels were released the greatest saccharified pentose and hexose sugars, the total fermentable sugars from them were 27.77 and 21.13 g.l-1, respectively. The co-fermentation were conducted by selected yeast strain belong to Kluyveromyces marxianus to contribute previously sexual regenerative Saccharomyces cerevisiae for bioethanol production.
As expected, the co-fermentation increased the bioethanol yield by more than 18% as average percentage for all saccharified peels. The substantial bioethanol yield were observed by saccharifed banana peels with 10.74 g.l-1, the adding of calcium oxide as drying agent lead finally to 97.5 wt % of pure bioethanol by duplicate the distillation process.
The reaction molar ratio of cocked oil to ethyl acetate were established by 0.1, 0.125, 0.2, 0.25, 0.5 and 1.0 mol.mol-1 respectively.
