Achyrocline satureioides review: From the pharmacochemical diversity to the technological development of products

Achyrocline satureioides (Lam.) DC (Asteraceae) is a native species of the southeastern subtropical and temperate region of South America, popularly known as "marcela" or "macela". This species is recognized, in traditional medicine, by diverse biological activities such as digestive, antispasmodic, anti-inflammatory, antiviral, sedative, hepatoprotective, among others. Some of these activities have been related to the presence of phenolic compounds, including flavonoids, phenolic acids, terpenoids in the essential oils, coumarins and phloroglucinol derivatives reported to the species. The approaches on the technological development of phytopharmaceutical products of this species provided relevant advances in the optimization of the extraction and product obtention, especially spray-dried powders, hydrogels, ointments, granules, films, nanoemulsions and nanocapsules. The most relevant biological activities described for the extracts or derivative products from A. satureioides were antioxidant, neuroprotective, antidiabetic, antiobesity, antimicrobial, anticancer effects, and obstructive sleep apnea syndrome. The scientific and technological findings reported for the species, in conjunction with its traditional use and cultivation, reveal the high potential of the species for diverse industrial applications.
