[Phenolic compounds isolated from rhizoma of Aster tataricus].
OBJECTIVE
To study the chemical constituents in root and rhizome of Aster tataricus.


METHODS
Compounds were isolated and purified by silica gel and sephadex LH-20 column chromatography. Their structures were identified by physicochemical properties and spectral analysis.


RESULTS
Nine compounds were isolated and identified as quercetin (I), kaemferol (II), emodin (III), chrysophanol (IV), physcion (V), benzoic acid (VI), p-hydroxy-bezoic acid (VII), E-caffeic acid (VIII), E-ferulic acid hexacosyl ester (IX).


CONCLUSIONS
Compounds IV, V, VI, VII, VIII, IX were isolated from A. tataricus for the first time.
