RESUMO
A study of the digestive effect of dates on sucrose and starch has been carried out. Digestion of sucrose and dates and starch and dates at pH 7.4 results in the breakdown of both sucrose and starch to glucose and fructose. On the contrary, digestion of sucrose and starch alone at pH 7.4 does not cause any breakdown suggesting that dates do affect the breakdown of sucrose and starch in the intestine. The variations in the analytical results are of the order of 1-2% in terms of RSD

The contents of macro-[Cd, Al, Pb, Mg, Ca, Na, K] and trace- metals [Cu, Ni, Cr, Fe, Mn] in ten edible medicinal plants have been determined by atomic absorption spectrophotometry using a wet digestion method. The overall reproducibility of the method is within = 10%. The results indicate large variations in the concentration of metals in plants samples studied. Out of the total contents of metals in these plants, the macro-metals including Cd [0.00024-0.00028%], Pb [0.00032-0.00047%], Mg [0.20-0.54%], Ca [0.32-0.39%], and Al [0.008-1.64%] are present in very low concentrations whereas Na [18.76-38.95%] and K [59.66-78.67%] are present comparatively in very high concentrations. Similarly, the trace elements, Cu [0.0022-0.016%]. Cr [0.16-0.44%] and Ni [0.38-0.66%] show the lowest concentration and Mn [2.59-14.50%] and Fe [84.36-96.87%] show the highest concentration which may be toxic to health
