RESUMO
OBJECTIVE: To study the chemical constituents in roots of Peucedanum praeruptorum from Henan. METHOD: The constituents were isolated by column chromatography on silica gel and ODS, and identified by NMR, MS spectroscopic methods. RESULT: 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. CONCLUSION: Compound 5 was a new compound, compounds 5 and 6 were isolated from Peucedanum plant for the first time.
