[Isolation and structure identification of chemical constituents from Saposhnikovia divaricata (Turcz.) Schischk].

Fourteen compounds were isolated from the ethanol extraction of Saposhnikovia divaricata (Turcz.) Schischk using column chromatographic methods after enrichment by macroporous adsorptive resins. They were identified as fangfengalpyrimidine (1), clemiscosin A (2), 5-hydroxy-8-methoxypsoralen (3), sec-O-glucosylhamaudol (4), hamaudol (5), nodakenetin (6), prim-O-glucosylcimifugin (7), cimifugin (8), 4'-O-beta-D-glucosyl-5-O-methylvisamminol (9), 5-O-methylvisamminol (10), marmesin (11), adenosine (12), daucosterol (13) and beta-sitosterol (14) by physico-chemical properties and spectral data. Compound 1 is a new compound. Compounds 2 and 3 were isolated from umbelliferae plants and Saposhnikovia divaricata (Turcz.) Schischk for the first time respectively.
