SUMMARY
Some chemical properties were determined in completely ripe fruits and fully developed leaves of black mulberry (Morus nigra L.) genotypes, grown inMahmatlar,Turkey. Crude protein was found as the most abundant component both fruits (10.25%) and leaves (25.72%). Native black mulberry fruits had higher content of total sugar (6.25%), crude fat (5.75%) and crude protein than those of the other berries. Also, mineral composition (K, Na, P, Ca, Mg, Zn, Fe, Mn and Cu) results indicated that K was the main nutrient of fruit followed by Na and P. Furthermore, black mulberry leaves were rich levels of sodium, calcium and potassium. Black mulberry should be more widely used because of its potential nutrient contribution for human and also feeding animals.
