title: Collagenase inhibitory quinic acid esters from Ipomoea pes-caprae.
abstract: Two new quinic acid esters (1 and 2) were isolated from the extract of Ipomoea pes-caprae together with six known quinic acid esters (3-8). The structures of compounds 1 and 2 were elucidated by spectroscopic data interpretation. These new compounds exhibited collagenase inhibitory activity and showed almost no cytotoxicity.
