ABSTRACT
<p><b>OBJECTIVE</b>To study the chemical constituents in root and rhizome of Aster tataricus.</p><p><b>METHODS</b>Compounds were isolated and purified by silica gel and sephadex LH-20 column chromatography. Their structures were identified by physicochemical properties and spectral analysis.</p><p><b>RESULT</b>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).</p><p><b>CONCLUSION</b>Compounds IV, V, VI, VII, VIII, IX were isolated from A. tataricus for the first time.</p>

<p><b>OBJECTIVE</b>To determine the content of shionone in Radix Aster from several different locations and markets.</p><p><b>METHOD</b>The HPLC analysis was used to determine shionone directly, using Polaris C18 column and acetonitrile as the mobile phase with a flow rate of 1.0 mL.min-1, and the UV detection wavelength was 200 nm.</p><p><b>RESULT AND CONCLUSION</b>The content of shionone was from 0.06% to 0.18%, depending on different locations and markets.</p>
