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.
Result: 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).
Conclusion: Compounds IV, V, VI, VII, VIII, IX were isolated from A. tataricus for the first time.
