A new putrescine bisamide phenolic glycoside, N-(trans-feruloyl)-N′-(para-hydroxybenzoyl) putrescine bisamide-4′-O-α- l -rhamnopyranoside (1), designated as lallenmantoside (1), together with one known phenolic glycoside, cucurbitoside d (2), were isolated from the seeds of Lallemantia iberica (M. Bieb.) Fisch. & C. A. Mey. Their structures were elucidated by spectroscopic analysis, and by comparison with literature data. This is the first report of phenolic glycosides from genus Lallemantia. |
