Résumé
<p><b>AIM</b>To study the chemical constituents of the stems and leaves of Aconitum coreanum (Lèvl.) Rapaics.</p><p><b>METHODS</b>The constituents of Aconitum coreanum were isolated by using various kinds of modern chromatographic methods. The new alkaloid was identified on the basis of spectral analysis.</p><p><b>RESULTS</b>Two compounds were isolated and identified as: 13-dehydro-1beta-acetyl-2alpha,6beta-dihydroxyhetisine (I) and Guanfu base G (II).</p><p><b>CONCLUSION</b>Compound I is a new alkaloid.</p>

<p><b>OBJECTIVE</b>To study the selective isolation of a single chemical component from volatile oil of Fructus foeniculi by inclucion method.</p><p><b>METHOD</b>The host molecule was selected and a single chemical component isolated from volatile oil by the host-guest recognition.</p><p><b>RESULT</b>X-ray single crystal analysis showed that 1,1,6,6-tetraphenylhexa-2, 4-diyne-1, 6-diol could successfully include 4-[1-propenyl] benzaldehyde from volatile oil of Fructus foeniculi.</p><p><b>CONCLUSION</b>The host-guest inclusion technology can be used to isolate a single component selectively from mixture.</p>
