Bioactivity, phytochemical profile and pro-healthy properties of Actinidia arguta: A review

Hardy kiwi (Actinidia arguta) is a climbing, perennial and dioecious vine from Actinidiaceae family, native from Asia and valued as ornamental and traditional medicine. In the last decade, the growing interest as fruit-bearing plant encourage the expanding cultivation of A. arguta mainly to fruits production, particularly in Europe and North America. A. arguta plants have an extensive range ofbioactive compoundsthat can be obtained from different botanical structures, such as fruits, leaves, flowers and stems. These bioactive molecules, with well-recognized health-promoting properties, include phenolic compounds, minerals, carbohydrates or even volatile substances, with a great potential to be used in several formulations of food products. Phytochemical studies on this plant reported hypoglycemic effects as well as antioxidant and anti-inflammatory activities, among others. The traditional uses ofA. arguta have been experimentally proved byin vitroandin vivostudies, in which its bioactivities were associated to its phytochemical composition. This review aims to assess and summarize the phytochemical and healthy properties ofthe different botanical parts of A. arguta, describing their bioactive composition and exploring it potential functional properties on foodstuffs.
