ABSTRACT


Eleven compounds belonging to eight structure types, namely cyclopentenedione (1), diketopiperazines (2, 9, 10), lactone (3), benzophenone (4, 5), terpene (6), anthraquinone (7), diphenyl ethers (10), and alkaloid (11) were isolated from the cultivation extract of the strain Aspergillus sp. CM9a, which was isolated from the stems of Cephalotaxus mannii. Among them, compounds 1, 2, and 3 were determined to b e new ones on the basis of spectroscopic data including 1D- and 2D - NMR experiments and HR Q-TOF MS. The structures of the eight known compounds were characterized based on their NMR data and by comparison with those reported.
