• Actinidia arguta is a source of bioactive compounds for food industry. • Bioactive compounds from A. arguta are reviewed. • A. arguta has high nutritional, functional and economic value. • Health promoting effects of A. arguta have been confirmed in vitro and in vivo. • A. arguta can be used in the prevention/treatment of chronic diseases (e.g. diabetes). 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 of bioactive compounds that 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 of A. arguta have been experimentally proved by in vitro and in vivo studies, in which its bioactivities were associated to its phytochemical composition. This review aims to assess and summarize the phytochemical and healthy properties of the different botanical parts of A. arguta , describing their bioactive composition and exploring it potential functional properties on foodstuffs.

Actinidia arguta is a climbing, fruit plant that recently generated a spread interest in many regions of the world, due to world globalization and knowledge expansion. During its production, different by-products are generated, such as fruits, leaves, stems, flowers and roots, being characterized by a rich bioactive composition that wise the scientific community for its health effects. Inboard of this panoply of valuable bioactive compounds, vitamin C, chlorogenic and neochlorogenic acids, caffeic acid, quercetin, catechin, kaempferol, p -coumaric acid, minerals and fatty acids play critical roles. As a result, the valorization and reuse of these by-products is a challenge, particularly for producers. This review aims to summarize the potential cosmetic and medical skincare applications of the different bioactive compounds from A. arguta by-products, describing and exploring their potential to contribute as active ingredients based on the biological activities reported. Simultaneously, a critical analysis of the patents available on the market regarding its use as cosmetic and medical skincare ingredient is provided. Cosmetic and medical skincare products could be a sustainable and green option for the use of A. arguta by-products bioactive compounds. Apart from contribute to skin appearance and health, the addition of these active compounds to the final cosmetic and pharmaceutical products may also provide skin beneficial effects such as photoprotection, anti-aging and anti-inflammatory effects, also acting as depigmenting and emollients, among other activities. Besides that, the impact on food by-product valorization and circular economy will be enormous.
