Determination of total phenolic content and antiradical activity in vitro of Prunus domestica L. leaves

Introduction. Research on plant materials plays a vital role in ensuring the safety and effectiveness of plant-based preparations within the healthcare system. In recent decades, studies have focused on analyzing the composition of biologically active compounds in plant raw materials, aiming to identify the most promising plants whose preparations could be utilized in medical practice, disease prevention, and complementary therapies [2]. The research focused on the leaves of medium-early Prunus domestica L. cultivars grown in Lithuania, specifically 'Ave', and 'Štaro vengrinė'. The compounds identified in the leaves of P. domestica exhibit a variety of biological effects, which are associated with phenolic compounds – natural antioxidants [6]. The compounds found in plum fruits are biologically active: they affect the cardiovascular system, have antimicrobial properties, and exhibit anticancer effects [5]. The lack of phytochemical studies on medium-early P. domestica leaves has prompted an investigation into the composition of phenolic compounds in the leaves of plums grown in Lithuania and the evaluation of the antioxidant activity of their extracts in vitro. The aim of the study was to determine the total phenolic compound content and antiradical activity in the leaves of two P. domestica cultivars. [...].
