Objective: To investigate the chemical constituents from the lateral roots of Aconitum carmichaelii. Method: A combination of various chromatographic techniques including column chromatography over silica gel

MCI

and Sephadex LH-20 were used to isolate the chemical constituents and their structures were elucidated by spectroscopic data analysis. Result: Twelve compounds were isolated and identified as nicotinamide (1)

uracil (2)

hypoxanthine (3)

adenosine (4)

uridine (5)

5-hydroxymethyl-pyrrole-2-carbaldehyde (6)

oleracein E (7)

cis-p-coumaric acid 4-O-β-D-glucoside (8)

cis-feruloyl-4-β-glucoside (9)

trans-feruloyl-4-β-glucoside (10)

isomaltol-glucoside (11) and 2

4

6-triphenylhex-1-ene (12). Conclusion: All the compounds were obtained from the genus Aconitum for the first time except compound 2.
