Chemistry and Biology of the GenusFlourensia(Asteraceae)

Abstract

Flourensia species are dominant plants that are adapted to semidesertic and desertic regions. It is believed that they are successful plants because they employ several protection mechanisms, including the formation of a waxy film on their aerial parts to protect them from dehydration. This waxy film contains chemical compounds that are capable of inhibiting the growth of other plants and of acting as allelopathic and herbicidal agents and as germination inhibitors. These plants also limit herbivory, and they exhibit insecticidal, insect antifeedant, antibacterial, antifungal, antialgal, and antitermite activities. Sesquiterpenes, flavonoids, benzofurans, chromenes, coumarins, lupan triterpenes, aliphatic lactones, and aromatic and acetilenic compounds have all been isolated from the organic extracts of Flourensia species. Monoterpenes, sesquiterpenes, and aliphatic hydrocarbons are the main constituents found in their essential oils. This review is an overview of the chemical constituents and of the biological activities of Flourensia species.

“…are wild plants that occur on a vast area from the south of USA crossing Mexico, Peru, Bolivia up to Argentina (Dillon, 1984). The genus Flourensia is formed by about 42 species, which at least nine of them have been found in Mexico (Rios, 2015), and three are considered as endemic of the state of Coahuila: F. cernua, F. microphylla, and F. retinophylla (Jasso de Rodríguez et al, 2007). F. cernua, commonly known as "hojasén" is the most studied species, as it has proven antifungal, antibacterial, and antioxidant properties (Jasso de its structure (Jasso de Rodríguez et al, 2017b;Stuppner and Müller, 1994;Dillon and Marby, 1977).…”
