Three new triterpenoid-type saponins were isolated from leaves of Duranta repens using plant growth inhibiting activity against seedlings of Brassica juncea var. cernua as a guide for fractionation. The structures of these compounds were elucidated as polygalacic acid-3-O-β-D-glucopyranosido- 28-O-[α-L-rhamnopyranosyl-(1 → 3')-β-D-apiofuranosyl-(l → 4)-α-L- rhamnopyranosyl(1 → 2)-β-L-arabinopyranoside] (durantanin I), polygalacic acid-3-O-β-D-glucopyranosido-28-O-[α-L-rhamnopyranosyl-(1 → 3)-β-D- xylopyranosyl-(1 → 4)-[β-D-apiofuranosyl-(1 → 3)]-α-L-rhamnopyranosyl-(1 → 2)-β-L-arabinopyranoside] (durantanin II), and polygalacic acid-3-O-β-D- glucopyranosido-28-O-[α-L-rhamnopyranosyl-(l → 3)-β-D-xylopyranosyl-(1 → 4)-α-L-rhamnopyranosyl(1 → 2)-β-L-arabinopyranoside] (durantanin III).
