Dibenzylbutyrolactone lignans and coumarins from Ipomoea cairica
From the aerial parts of Ipomoea cairica (L.) Sweet (Convolvulaceae) the coumarins umbelliferone and scopoletin, and the dibenzyl-g-butyrolactone lignans arctigenin, matairesinol and trachelogenin, were isolated along with b-sitoterol and fatty acids. The analysis of the RMN 13C spectra of these and other lignoids described in the literature made it possible to revise some chemical shift assignments.
