Abstract
Parsley (Petroselinum crispum Mill) is used as a raw material in the food industry because it has, among other things, a high content of phenolics. Under the research study presented, the impact of solvents on the content and some selected biological properties of P. crispum extracts was studied. The following extracts were compared: aqueous (W), ethanolic (ET), aqueous-glycolic (GLW), and aqueous-glycerinic (GCW). The highest concentration of total phenolics was determined in the GLW (2.63 ± 0.03 mg/g sm) and GCW (2.12 ± 0.08 mg/g sm) extracts, while the ET extract contained the highest amount of flavonoids (0.86 ± 0.02 mg/g sm). In the W extract, epicatechin, catechin and its derivates were the main phenolic compounds, in the ET extract: phenolic acids (e.g. rosmarinic acid), in the GLW extract: apigenin, and in the GCW extract: daidzein, naringenin, and the derivates. In addition to significant differences in the quantitative and qualitative composition of the extracts analysed, their antioxidant activity was highly differentiated. The GCW extract neutralized the DPPH• radical to the greatest extent (IC50 = 6.89 ± 0.56 µg/ml) and the W extract: the ABTS•+ radical (IC50 = 31.44 ± 4.11 µg/ml). All the extracts had a comparable ability to chelate Fe2+ ions. The in vitro analysis of cytotoxicity of the extracts against the BJ human cell line (ATCC CRL-2522) demonstrated that the ET and W extracts were the most cytotoxic ones. The cytotoxicity of GLW and GCW extracts was comparable to the cytotoxicity of that of the solvents. The impact was proved of the solvents on the content, antioxidant properties, and cytotoxicity of P. crispum leaf extracts, and, at the same time, it was suggested that it would be possible to use those extracts in the food, pharmaceutical, and cosmetic industry.
