Introduction: Cornus is a very large genus which comprises 40 species of shrubs and trees native to Central and Southern Europe and parts of Western Asia. Many species are grown as ornamentals. Only a few species are grown for their fruits, chief among which is the cornelian cherry (Cornus mas L.). Study on the nutritional value of the cornelian cherry has focused on nutrients which play a role in preventing diseases such as scurvy. Fresh cornelian cherry fruits contain twice as much vitamin C as oranges. The aim of this study was to investigate the distribution and physicochemical properties of cornelian cherry (Cornus mas L.) fruits in Iran.
Materials and Methods: Distribution of cornelian cherry was traced on the map according to the visitation of the different provinces. In order to study the characteristics of the fruit, samples were taken from five different areas and various parameters were evaluated. Fruit and seed weight (g) were measured by a digital balance with a sensitivity of 0.001 g (Scaltec Company, Gottingen, Germany; model SPB31). Fruit length (mm), fruit diameter (mm), seed diameter (mm) and seed length (mm) were measured using a digital vernier caliper with a sensitivity of 0.01 mm. TSS was determined by refrectometry of one drop extracted juice of each fruit at 25°C (Kyoto Electronics Manufacturing Co. Ltd., Japan, and Model RA-250HE). TA was determined by titration and the pH value was indicated by pH meter (HBJ-260). In addition, total ascorbic acid content was determined by the dinitrophenylhydrazine (DNPH) method. Data were subjected to calculate of descriptive statistics by SPPSS and means were separated by Duncan’s multiple range test at p
