Callus cultures of Spergularia marina (L.) Griseb.: obtaining and phytochemical analysis
... particular interest, the biological activity and content of secondary metabolites of which have not been studied sufficiently. The purpose of this study was to obtain callus cultures, to study the content of some groups of phenolic compounds and the antioxidant activity of extracts. The study carried out the selection of growth regulators and concentrations that induce callus formation. 19 nutrient media were selected for the induction of S. marina callus cultures. The conducted phytochemical analysis showed ...
Comparison of the methods of total antioxidant activity analysis
Five varieties of apples from the Baltic region were studied by means of two different analytical methods. The results of experiment demonstrate that the values of total antioxidant activity obtained through spectrophotometric and amperometric methods are comparable. The authors determined the relation between the total content of ascorbic acid and phenolic compounds in apples, pulp, and juice of the variety.

Comparative evaluation of the biological effect of native and synthesized peptides
... do not differ from natural ones in terms of physical and chemical characteristics. Both synthesized and natural peptides are non-toxic. The anti-diabetic effect of natural and synthesized peptide mpT2 on animals with induced type 2 diabetes and the antioxidant activity of synthesized and natural peptide T1.1 have been demonstrated.
