OBJECTIVE
To study the chemical constituents in the dried roots of Saposhnikovia divaricata.
METHODS
The chemical constituents were isolated by various column chromatographic methods and structurally elucidated by IR, UV, MS and NMR evidences.
RESULTS
Eighteen compounds were obtained and identified as 3'-O-angeloylhamaudol (1), isobergapten (2), imperatorin (3), pentacosane acid (4), anomalin (5), decursin (6), 5-methoxy-7-(3,3-dimethylallyl- oxy)coumarin (7), decursinol angelate (8), xanthotoxin (9), bergapten (10), tectochrysin (11), scopoletin (12), hamaudol (13), ledebouriellol (14), cimifugin (15), sec-O-glucosylhamaudol (16), 4'-O-beta-D-glucosyl-5-O-methylvisamminol (17), and prim-O-glucosylcimifugin (18).
CONCLUSIONS
Compounds 2, 6-8, and 11 were isolated from the roots of S. divaricata for the first time. Compounds 1 and 13-18 were chromones, 2, 3, 5-10 and 12 were coumarins, 4 was fatty acid, and 11 was flavonoid.
