“…Lignin is a macromolecule formed from glucose metabolism via shikimic acid, with phenylpropanoid precursors such as eugenol . Some species of Maytenus such as M. gonoclada are still under controversial delimitation since they exhibit strong morphological variation . This controversy is supported by the essential oil profiles of M. gonoclada , which distinguished from the other Maytenus species evaluated by PC2 and PC3.…”

Extracts and compounds obtained from several species of Celastraceae family are reported as potential sources of drugs due to their diverse pharmacological properties. Nevertheless, essential oil composition from these species is still little known. This work aimed at the analysis of essential oils obtained from different Brazilian Celastraceae species. A total of seventeen oils were obtained using hydrodistillation process and analyzed by gas chromatography/mass spectrometry (GC/MS). Principal component analysis (PCA) allowed the identification of a chemical composition pattern among the analyzed essential oils. Some compounds were more frequent among Celastraceae species, such as cis‐ and trans‐linalool oxide (14/17 oil samples), nerylacetone (13/17), linalool (11/17), β‐ionone (10/17), α‐ionone (9/17), nerolidol (10/17), decanal (10/17), and dodecanoic acid (10/17). These results contribute to the chemophenetics of Celastraceae species.

“…They are found in the tropics and subtropics, with some rare representatives in temperate regions (Loesener, 1942;Simmons et al, 2001aSimmons et al, , 2001bSimmons, 2004). The genus Maytenus Molina (1782: 177) has traditionally been treated as a large genus of about 300 species that is widely distributed in tropics and subtropics of both the Old and New Worlds (McKenna et al, 2011;Biral et al, 2017).…”

The nomenclatural types of Celastrus senegalensis Lam., basionym of the current name Maytenus senegalensis (Lam.) Exell, and C. europaeus Boiss., basionym of M. senegalensis subsp. europaea (Boiss.) Rivas Martínez ex Güemes & M.B. Crespo (Celastraceae, Celastroideae), are discussed. A specimen preserved in the herbarium P, at the Museum national d’Histoire naturelle of Paris, is treated in this work as the neotype of M. senegalensis, and a specimen kept in the herbarium G, at the Conservatoire et Jardin botaniques of Genève, is designated as the lectotype of M. senegalensis subsp. europea.

“…ex Reiss.) (Biral et al 2017) is popularly known as "espinheira-santa", and extensively used in the treatment of several diseases, especially gastritis and dyspepsia (Santos-Oliveira et al 2009). The genus Maytenus belongs to the family Celastraceae and was first described by Feullèe (1725), however, the first valid description for the genus was only published by Molina in 1782.…”

A chemophenetic study of the genus Maytenus s.l. (Celastraceae): contribution to the rational search of its bioactive metabolites

Maytenus s.l. is a genus of the Celastraceae family and many of its species are used in traditional medicine. Most of the substances responsible for the biological activities of plants come from their secondary metabolism, such as terpenoids and flavonoids, which have multiple functions in the plant and can occur in a similar way in plant groups. Chemophenetics analyzes the occurrence of these substances in a taxon and can infer evolutionary trends and contribute to the rational search for new drugs. Chemosystematic parameters were used to analyze the data obtained through a bibliographic survey. The species of Maytenus s.l. were separated into three groups: species with accepted names, synonymous species with the genus Monteverdia and synonymous species with the genus Gymnosporia. Due to their great occurrence and structural variety in Maytenus s.l., triterpenes were chosen as chemosystematic markers, with friedelanes and quinone methide triterpenes being the most expressive types. Studies have already demonstrated the analgesic potential of quinone methides and the antitumor potential of phenolic triterpenes and dimers of these units. Together, the three classes assist in the circumscription of Maytenus s.s. and Monteverdia, while lupanes can be used in the separation of these genera. Oleanans are representative of Gymnosporia.
