Effect Of Crude Methanolic Extracts Of Some Fruit Tree Leaves On Some Blood Constituents Of Diabetic Rats.

Crude methanoilc extracts of thompson seedless, flame seedless, zizyphus, pomegranate and fig leaves were prepared. In this work the efficiency of the investigated extracts has been studied to elucidate their activities on some blood constituents of diabetic rats. The most effective treatment was the methanolic extract of zizyphus leaves which decreased blood glucose level to 128.33mg/dl at a dose of 40mg/100g body weight after 30 days where the maximum reduction of about 66.95% was obtained comparing with control diabetic rats. Whereas treatments of streptozocin diabetic rats with methanolic extract of thompson seedless leaves resulted the maximum percentage of reduction in ALT activity with 60.91% after 30 days by using 40mg/100 body weight. Extract of flame seedless leaves was the most effective for reduction of AST enzyme with a percentage of 46.23% a…

Delaying Guava Riprning By Exogenous Salisylic Acid.

The experiment was conducted to study the effect of exogenous salicylic acid (SA) treatment (water, 100, 300 and 500 μM) on fruit repining of guava cv 'Baladi' during 12 days shelf-life at room temperature. Fruit were harvested at three different color maturities green mature stage (G), green yellow (GY) and yellow stage (Y). Thereafter, fruits were immersed in SA solutions for 20 min. Fruit were immersed at high level 500 μMhad less IL%, degradation in total phenol, fruit browning and maintained the amount of vitamin C. Moreover, it had higher fruit firmness and color (hO), compared with other concentrations of SA and water-control.

Effect Of Organic And Inorganic Salts On Mycelial Growth, Sporulation And Spore Germination Of Potato Postharvest Pathogens.

Ten organic and inorganic salts were tested for suppression of Fusarium solani, a causal agent of potato dry rot, and silver scurf, a postharvest disease of potato tubers caused by Helminthosporium solani. Ammonium acetate, ammonium chloride, ammonium tartarate, calcium chloride dehydrate, magnesium sulfate, potassium dihydrogen phosphate, potassium iodide, sodium benzoate, sodium bicarbonate and sodium sulphate were added to Potato Dextrose Agar (PDA) at concentrations of 0.1 M, 0.2 M and 0.4 M. Several salts significantly inhibited the mycelial growth, sporulation and spore germination of F. solani and H. solani. The mycelial growth of both tested fungi was completely inhibited by sodium benzoate at the lowest concentration (0.1 M). Sporulation of pathogens was strongly inhibited by sodium benzoate (100%) at all concentrations. Some sa…

Dill Extract As Green Inhibitor For The Corrosion Of Carbon
Steel In H3PO4Solution.


The inhibiting effect of dill extract (DE)
on the corrosion of C-steel in 1 N H3PO4 was studied by
weight loss, potentiodynamic polarization, electrochemical impedance
spectroscopy (EIS). The results showed that the inhibition efficiency
increases with increasing the inhibitor concentration, while it decreases
with increasing the temperature. The adsorption of dill extract on the C-steel
surface obeys Langmuir adsorption isotherm. Some thermodynamic parameters
were calculated and discussed. The values of free energy of adsorption for
investigated inhibitors were calculated. Polarization curves show that dill
extract is mixed-type inhibitors. The results obtained from chemical and
electrochemical techniques are in good agreement.
