RESUMO
<p><b>OBJECTIVE</b>To study the chemical constituents in roots of Peucedanum praeruptorum from Henan.</p><p><b>METHOD</b>The constituents were isolated by column chromatography on silica gel and ODS, and identified by NMR, MS spectroscopic methods.</p><p><b>RESULT</b>Six compounds, Pd-I b(1), marmesinsin (2), rutarin (3), isorutarin (4), 4H-1-benzopyran-4-one, 5-hydroxy-6-methoxy-2-phenyl-7-O-alpha-D-glucuronyl methyl ester (5), 4H-1-benzopyran-4-one, 5-hydroxy-6-methoxy-2-phenyl-7-O-alpha-D-glucuronyl acid (6) were isolated and identified.</p><p><b>CONCLUSION</b>Compound 5 was a new compound, compounds 5 and 6 were isolated from Peucedanum plant for the first time.</p>
