Two new pentacyclic triterpene acids, mimusopic and mimusopsic acids,
possessing the novel migrated oleanane skeleton, mimusopane were isola
ted from the seeds of Mimusops elengi and were respectively defined as
a,23-trihydroxy-5,10-friedooleana-9,12-dien-28-oic acid and 2beta,3be
ta-dihydroxy (23 --> 10)-oxido-5,10-friedooleana-9(11),12-dien-28-oic
acid based on their spectroscopic properties and chemical transformati
