Abstract
Two new coumarin glycosides, namely nitensosides A-B (1-2), together with six known compounds, scopolin (3), 5,6,7-trimethoxycoumarin (4), d-calycanthine (5), calycanthoside (6), xeroboside (7), and scopoletin (8), were isolated from Chimonanthus nitens. The structures of the new compounds were elucidated by comprehensive analysis of IR, MS, and NMR spectroscopic data. Compounds 3, 4, 7, and 8 showed moderate inhibitory activity against Micrococcus luteus.
