The present study was focused to evaluate the phytochemical screening and biochemical estimation of ethanolic aqueous extracts edible nuts Arachis hypogea, Anacardium occidentale, Prunus dulcis Juglans regia. showed presence carbohydrate, protein, phenol tannin, flavonoid, glycoside, steroid, alkaloid in all studied nuts. quantification A. hypogeae, P. J. regia were performed determine total am...

The acyclic polyol sorbitol is a primary photosynthetic product and the principal photosynthetic transport substance in many economically important members of the family Rosaceace (e.g. almond [Prunus dulcis (P. Mill.) D.A. Webber], apple [Malus pumila P. Mill.], cherry [Prunus spp.], peach [Prunus persica L. Batsch], and pear [Pyrus communis]). To understand key steps in long-distance transpor...

Inorganic copper is used as a broad-spectrum fungicide and bacteriocide on a variety of agricultural crops. After application, the copper residue typically accumulates in the upper 15 cm of soil. Data from the California Pesticide Use Reports were used to estimate the augmentation of copper in the soil that resulted from pesticide applications for the six years from 1993 to 1998 on 12 crops tha...

Acrylamide is a carcinogenic and neurotoxic compound defined as heat treatment process contaminant. Due to its health concern, acrylamide formation needed be minimized. The objective of this study examine how much contained in dried almonds (Prunus dulcis), hazelnuts (Corylus avellana), pistachios (Pistacia vera), peanuts (Arachishypogaea), sunflower seeds (Helianthus annuus) well pumpkin (Cucu...

The relationship between the levels of cyanogenic compounds (amygdalin and prunasin) in kernels, leaves, and roots of 5 sweet-, 5 slightly bitter-, and 5 bitter-kernelled almond trees was determined. Variability was observed among the genotypes for these compounds. Prunasin was found only in the vegetative part (roots and leaves) for all genotypes tested. Amygdalin was detected only in the kern...

Under normal environmental conditions, many plants synthesize cyanogenic glycosides, which are able to release hydrogen cyanide upon hydrolysis. Each year, there are frequent livestock and occasional human victims of cyanogenic plants consumption. The present work aims to determine the hydrocyanic acid content in different samples of cyanogenic plants, selected from the Tunisian flora, and in t...

Measurements made by several laboratories may exhibit non-negligible between-laboratory variability, as well as diierent within-laboratory variances. Also, the number of measurements made at each laboratory often diier. A question of fundamental importance in the analysis of such data is how to form a best consensus mean, and what uncertainty to attach to this estimate. An estimation equation a...
