Abstract

From the roots of Ligularia intermedia, two new naturally occurring 3,4-seco-oleanolic triterpene acids were isolated. Their structures were elucidated as A-homo-3a-oxa-olean-12-en-3-one-28-oic acid (1) and 3,4-seco-olean-12-en-4-ol-3,28-dioic acid (2) by spectroscopic methods and chemical transformations. In addition, six known compounds (5-10) were also obtained from this plant.
