Phytochemical studies of . Hortia brasiliana and . Hortia oreadica (Rutaceae) have led to the identification of three novel dihydrocinnamic acids: 5-methoxy-2,2-dimethyl-2. H-1-benzopyran-8-propanoic acid, 5,6-dimethoxy-2,2-dimethyl-2. H-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. © 2012 Elsevier Ltd.
