METHODS AND RESULTS:
The chemical constituents were isolated by various column chromatographic methods and structurally elucidated by NMR and MS evidences. Twenty-four compounds were obtained and identified as isocalamenediol (1), pregnenolone (2), beta-sitosterol (3), bergapten (4), bergaptol (5), cnidilin (6), isoimperatorin (7), bergamottin (8), demethylfuropinnarin (9), nodakenetin (10), 7'-O-methylnotoptol (11), notopterol (12), notoptol (13), pabulenol (14), phenethylferulate (15), p-hydroxyphenethyl anisate (16), trans-ferulic acid (17), nodakenin (18), sucrose (19), 2-methoxy-4-(3-methoxy-1-propenyl)-phenol (20), 3,4,5-Trimethoxy-trans-cinnamic acid(21), p-methoxycinnamic acid (22), 4-acetoxy-3-methoxy-trans-cinnamic acid (23), and p-hydroxy-trans-cinnamic acid (24).
CONCLUSIONS:
Compounds 1, 14, 20-24 were isolated from the roots and rhizomes of N. incisum for the first time. Compounds 1 and 14 are sesquiterpenoid and coumarin, respectively, and 20-24 were phenylpropanoid compounds. |
