Flowers are the most fragile plant organ that contains a wide range of variable compounds. Due to their nutritional, pharmacological and aromatic properties, they have been used in several products, from food to the pharmaceutical, and textile industries. The supercritical fluid extraction of valuable components has been highlighted in the literature, since their advantages are related to the protection of photosensitivity, oxidizability and volatility of biocompounds, leading to a remarkable benefit of the used method. From pigments to aromatic compounds, passing through the alkaloids, these compounds can be extracted tunning the process conditions or using different strategies during the supercritical fluid extraction. Commercial products have been produced from flowers using this technology, such as the very well-known cannabis. This review intends to present the literature from the last two decades, as well as the challenges and advantages of performing supercritical fluid extraction with this delicate and sensitive raw material: the flowers.

花是最脆弱的植物器官，含有多种可变化合物。由于它们的营养、药理和芳香特性，它们已被用于多种产品，从食品到制药和纺织工业。有价值成分的超临界流体萃取在文献中得到了强调，因为它们的优点与保护生物化合物的光敏性、氧化性和挥发性有关，从而使所使用的方法具有显着的优势。从颜料到芳香族化合物，通过生物碱，这些化合物可以在超临界流体萃取过程中调整工艺条件或使用不同的策略进行萃取。商业产品已经使用这种技术从花卉中生产出来，例如非常有名的大麻。
