Abstract: The Brazilian flora is among the most diverse in the world, comprising a diversity of species, 40% of which are endemic. This biodiversity is the basis of food production, strategic for biotechnology and innovation in food technology, as well as for sustainability. Part of this wealth remains underutilized and incipiently used in the food menu. Edible flowers, considered unconventional food plants, include a series of potentially important bioactive compounds to promote the health of those who consume them, and it is essential to identify their biological and nutritional characteristics in order to favor the growing demand for functional foods and nutraceuticals. The objectives of this research were to carry out a bibliographic review on the biological and ecological characteristics of the night-lady (Ipomoea alba L. - Convovulaceae), the inca-lily (Alstroemeria psittacina Lehm - Allstroemeriaceae) and the mountain cork-tree (Erytrina falcata Benth. - Leguminosae), as well as analyzing groups of bioactive compounds from these native species with unconventional food flowers. The flowers were collected in different municipalities in the Vale do Taquari, the bioactive compounds total polyphenols, flavonoids, tartaric esters, tannins and anthocyanins were analyzed through spectrophotometric analysis. It can be seen from the literature review carried out that all species occur naturally in the studied territory, being of great ecological importance in plant formations, however they are still neglected, where the lady-of-the-night and the inca-lily still they carry with them the idea of being wild and wild, and practically unknown for food use. In relation to the bioactive compounds analyzed, it was found that these flowers can be promising sources of biological and antioxidant activities beneficial to the health of consumers, being able to complement the daily diet and, at the same time, it is recommended to continue research, enabling its recognition as food, contributing to conservation through use and regional agrobiodiversity.
