Coumarins from Seseli hartvigii Roots

Abstract

Three angular-type pyranocoumarins, (-)-anomalin (1), (+)-(3'R,4'R)-3′,4′-disenecioyloxy-3′,4′-dihydroseselin (2), and (-)-(3'R,4'R)-3′-angeloyloxy-4′-acetoxy-3′,4′-dihydroseselin (3), two linear-type furocoumarins, bergamottin (4) and isoimperatorin (5), and a simple coumarin, suberosin (6) have been isolated from the roots of Seseli hartvigii (Umbelliferae). The structures of these compounds were determined from spectral and physical information, and with reference to literature data.
