Coumarins from the aerial parts of Prangos uloptera (Apiacease)

Abstract

Phytochemical, studies on the acrid parts of Prangos uloptera, an endemic Iranian species of the genLIS Prong6s, yielded five cournarins, xanthotoxin (1), prangenin (2) scopoletin (3), deltoin (4) and prangqlarin (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.
