Abstract
The study was about the estimation of proteins, carbohydrates, phenolic and flavonoid compounds, Anthocyanins pigment and carotene, also measuring the acidity (pH) and electrical conductivity, as well as we carried out the counter effectiveness test of oxidation and the biologic effectiveness test. The results obtained showed that the fruits and leaves of both of the two types of the berries ,Have nearly the same amount of proteins and carbohydrates, also the leaves of M.nigra and the fruits of the M.alba have bigger amount of phenols and flavonoid . and as for the pigments , the fruits M. alba and the leaves M. nigra, the amount of anthocyanins and there was a high amount of carotene in both types. Regarding the acidity (pH), it was mostly moderate where it tends to alkalinity in the leaves of M. alba, and tends to acidity in the fruits of M. nigra. while the electrical conductivity was nearly the same amoung the two types of fruits and leaves of M. nigra. A low salinity was observed in the leaves of M. alba. M. nigra have higher bacterial inhibition activity and anti-oxidant activity compared to M. alba
