摘要：

A new nor-triterpene glycoside, pyrocincholic acid 3-beta-O-beta-6-deoxy-D-glucopyranoside-28-O-beta-D-?? glucopyranoside, was isolated from aerial parts of Isertia haenkeana. Its structure was established on the basis of its spectral data and some chemical transformations. The 13CNMR data are presented for cincholic acid. A comparison with the data reported for quinovic acid is carried out.
