ABSTRACT
Phytochemical studies on the aerial parts of Prangos uloptera, an endemic Iranian species of the genus Prangos, yielded five coumarins, xanthotoxin (1), prangenin (2), scopoletin (3), deltoin (4) and prangolarin (5). The structures of these coumarins were elucidated by spectroscopic means, and the antioxidant potential of 1-5 was evaluated by the DPPH assay. The chemotaxonomic significance of 1-5 is also discussed.
RESUMO
Os estudos fitoquímicos das partes aéreas de Prangos uloptera, uma espécie do gênero Prangos endêmica do Irã, forneceram cinco cumarinas, xantotoxina (1), prangenina (2), escopoletina (3), deltoína (4) e prangolarina (5). As estruturas destas cumarinas foram elucidas através de métodos espectroscópicos e o potencial antioxidante de 1-5 foi avaliado pelo ensaio de DPPH. O significado quimiotaxonômico de 1-5 também é discutido.
