摘要：In this research, the blackberry widely grown samples supplied from four different locations of Samsun and surrounding were used. In the samples total solid, soluble solid, refractive index, titratable acidity, citric acid, pH, invert sugar, total sugar, glucose fructose, sucrose, pectin, crude, fiber, protein, formol, proline, crude oil, ascorbic acid ash, total phenolic matter, total anthocyanine, mineral matter (K, Ca, P, Mg, Na, Fe, Zn, Mn, Cu) were determined respectively. And also phenolic compounds and organic acid were determined by using HPLC. As a result of this analysis its found that glucose fructose ratio varied between 1.02 and 1.05, the mean value of sucrose was about 0, and the samples were rich in potassium (mean value 1698.10 mg/kg) and calcium (mean value 508.60 mg/kg). According to the results of HPLC analysis, the most abundant phenolic compounds, anthocyanine and organic acid of the blackberries were found as quinic acid (mean value 475.26 mg/l) and catechin (mean value 122.31 mg/l), cyandine-3 glycoside (mean value 831.20 mg/l) and malic acid (mean value 5.33 g/kg) respectively.
