Chinese jujube is one of the most commonly used fruit in Chinese herbal medicine, being considered by the researchers and nutritionists a super fruit in terms of nutrition. In Romania, more than 20 genotypes were introduced from China, in the Experimental Field of the Faculty of Horticulture within the UASVM Bucharest. This study aims to present several biochemical characteristics of ten Chinese jujube genotypes. Fresh fruits were harvested at the beginning of September until October. After morphological measurements, fruits were stored at 2-3 ̊ C and 90-95% relative humidity. For analysis hydro alcoholic extracts using 1:10 ratio was used. The extracts were subjected to spectrophotometric analysis. Using Folin - Ciocâlteu method, the total phenolic content of the extracts was determined. The flavonoid content was identified using an adapted method based on rutin equivalent. The free radical scavenging activity of the extracts was determined using 2,2 diphenyl-1-picrylhydrazyl radical. The obtained results confirm the data presented by the researches on the similar genotypes and can be an important aspect in promoting the cultivation and consumption of these fruits in more regions of our country.
