Studies on the chemical constituents in herbs of ethanolic extract from herbs of Dicliptera chinensis / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the chemical constituents of ethanolic extract from herbs of Dicliptera chinensis.</p><p><b>METHOD</b>The compounds were separated by silica gel column chromatography, preparation TLC and reverse phase HPLC, their structures were identified by the spectroscopic methods of UV, NMR and MS.</p><p><b>RESULT</b>Seven compounds were isolated from ethyl acetate extract. Their structure were identified as octasulphur (1), secoisolariciresinol dimethyl ether diacetate (2), 5-methoxy-4, 4'-di-O-methyl secolariciresinol (3), chinensinaphthol methyl ester (4), loliolide (5), beta-sitosterol 3-O-beta-D-glucopyranoside (6) and stigmasterol 3-O-beta-D-glucopyranoside (7).</p><p><b>CONCLUSION</b>All the compounds except 6 were obtained from the plants of Dicliptera for the first time.</p>
