Abstract

Besides serratagenic acid, three new ursane-type triterpenes, named goreishic acids I (1), II (2), and III (3), were isolated from a Chinese medicine, Goreishi(the feces of Trogopterus xanthipes MILNE-EDWARDS). The structures of 1, 2 and 3 were respectively determined as 2α, 3β-dihydroxyursa-12, 18-dien-28-oic acid, 2α, 3β-dihydroxy-23-norursa12, 18-dien-28-oic acid and 2α, 3β-dihydroxy-24-norursa-12, 18-dien-28-oic acid on the basis of spectroscopic evidence.
