This overview article contains information about pyranocoumarins over the last 55 years. The article is based on the authors’ phytochemical and physiological studies in vivo and in vitro as well as search and analysis of data in literature available on Google Scholar, Web of Science, PubMed, and ScienceDirect before January 2022. Pyranocoumarins are synthesized in plants of the Apiaceae, Rutaceae families, and one species in each of the Cornaceae, Calophyllaceae, and Fabaceae families can synthesize this class of compounds. The physiological role of these compounds in plants is not clear. It has been proven that these substances have a wide range of biological activities anti-cancer, anti-spasmatic, and anticoagulant, and they also inhibit erythrocyte lysis and accumulation of triacylglycerides. The overview generalizes the modern understanding of the classification, structure, and biological activity of natural pyranocoumarins, and summarizes dispersed data into a unified scheme of biosynthesis. The review analyzes data on the localization and productivity of these substances in individual organs and the whole plant. It discusses a link between the unique structure of these substances and their biological activity, as well as new opportunities for pyranocoumarins in pharmacology. The article evaluates the potential of different plant species as producers of pyranocoumarins and considers the possibilities of cell cultures to obtain the end product.

Fragaria orientalis is the most distributed wild strawberry in the North Asia, and it is consumed in large quantities by the local population. However, poor knowledge of the chemical composition, metabolic profiles, and bioactivity leads to the insufficient use of F. orientalis beyond the region. The aim of our study was to investigate the nutritional value, chemical composition, and sensory parameters of wild and cultivated F. orientalis fruits, before and during postharvest storage. Sixty-five compounds were identified by liquid chromatography–mass spectrometry (LC–MS). Wild and cultivated fruits have the same LC–MS profiles, but quantitative levels varied, in favor of the wild samples. The extracts of F. orientalis fruit demonstrated high radical-scavenging potential, and ascorbic acid and various phenolics were identified as principal antioxidants. Significant variation in ascorbic acid, phenolic content, and total antioxidant potential was found during storage of the fresh F. orientalis fruit at cold and room temperatures and in defrosted fruits; storage of the dried fruits at cold temperature showed the lowest loss of bioactive compounds. The new information on postharvest changes in the phytochemicals and bioactivities provide a better understanding of the processes occurring in fresh, frozen, and dried strawberry fruits during storage.
