Dihydrocinnamic acid derivatives from Hortia species and their chemotaxonomic value in the Rutaceae

Publication date: August 2012 Source:Biochemical Systematics and Ecology, Volume 43 Author(s): Patricia A.C. Braga , Vanessa G.P. Severino , Sâmya D.L. de Freitas , Maria Fátima das G.F. da Silva , João B. Fernandes , Paulo C. Vieira , José R. Pirani , Milton Groppo Phytochemical studies of Hortia brasiliana and Hortia oreadica (Rutaceae) have led to the identification of three novel dihydrocinnamic acids: 5-methoxy-2,2-dimethyl-2H-1-benzopyran-8-propanoic acid, 5,6-dimethoxy-2,2-dimethyl-2H-1-benzopyran-8-propanoic acid and erythro-2-hydroxy-4-methoxy-3-(1,2,3-trihydroxy-3-methylbutyl)benzenepropanoic acid from H. brasiliana and the second compound and six known dihydrocinnamic acids from H. oreadica. Engler included Hortia as the single Neotropical genus in the Toddalioideae subtribe Toddaliinae. However, the range of dihydrocinnamic acid derivatives found in H. brasiliana and H. oreadica show that they contain similar compounds to other species of Hortia and clearly point to their phytochemical affinities with other Rutoideae species. Graphical abstract Highlights Studies of the rutaceous species Hortia brasiliana and Hortia oreadica have led to the identification nine dihydrocinnamic acids, whose chemosystematic significance is discussed. ► Nine dihydrocinnamic acids were isolated from Hortia brasiliana and Hortia oreadica. ► Three novel dihydrocinnamic acids were characterized. ► The chemotaxonomic value of the dihydrocinnamic acids in the Ru...
