摘要

Two new nor-diterpenoids called perangustine (1) and perangustinine (2) were isolated from roots of Perovskia angustifolia (Lamiaceae). The chemical structures of the isolated compounds were proved based on IR, UV, 1H and 13C NMR spectral data and COSY, HSQC, and HMBC experiments. The molecular structure of perangustine was established by an X-ray crystal structure analysis.
