Biochemical characteristics of parsley varieties (Petroselinum crispum [Mill.] Nym. ex A.W. Hill.)

High nutritional value of parsley determines constant interest to this agricultural crop as a source of natural antioxidants to humans. Biochemical characteristics of 6 parsley varieties (Federal scientific center selection) are investigated. Dry matter content was in the range 20.56-25.92%. Monosaccharides concentrations varied from 1.29 to 2.14%. High correlation between dry matter and monosaccharides content in leaves was revealed (r=0.97). The highest concentration of ascorbic acid was demonstrated in leaves of two varieties: Nezhnost and Breeze. The highest antioxidant activity and polyphenol content were typical for leaves of root-parsley and curly variety Krasotka (45.1 mg-eq GA/g d.w., 16.6 mg-eq GA/g d.w. and 55.55 mg-eq GA/g d.w., 15.8 mg-eq GA/g d.w. accordingly). Antioxidant activity level was found to be strictly connected with the content of ascorbic acid and a strong correlation was demonstrated between these parameters (r=0.92, P
