استقصاء وتقدير بعض العناصر المعدنية في ثمار البلوط والسنديان وحب الاس البرية باستخدام طرائق التحليل الطيفية والحجمية

Quantitative study has been made for some mineral elements, such as: calcium, magnesium, potassium, sodium and iron in the achenes of oak trees (q. calliprions and q. infectoria) and wild myrtle, which are spread in the valleys and mountains of Syrian coast by using volumetric analysis (complexemetric and reduction-oxidation titrations ) and spectroscopic analysis (flame spectroscopy). The results of this study showed that the achenes of myrtle contain high concentrations of iron (2.50 mg/kg), magnesium (0.025 mg/kg), and potassium (181 mg/kg), when it is compared with the achenes of quercus calliprions and quercus infectoria. Also, it was found that sodium (97.3 mg/kg) and calcium (0.370 mg/kg) in the achenes of quercus calliprinos with a higher rate than in the other achenes. It is also important to say, that the epicarps of the achenes of quercus calliprinos and quercus infectoria contain high concentrations of magnesium (0.030 mg/kg) and (0.339 mg/kg), respectively.
