Objective:
To isolate and identify the chemical constituents from the roots of Peucedantu praeruptorum.
Method:
The constituents were isolated by column chromatography on silica gel and ODS, and identified by NMR, MS spectroscopic methods.
Result:
Eight compounds, (-) sclerodin (1), palmitic acid (2), (+)-praeruptorin E (3), bergapten (4), imperatorin (5), 2,6-dimethyl quinoline (6), tetracosanoic acid (7), and daucosterol (8), were isolated and identified.
Conclusion:
Compounds 1,5-7 were isolated from this plant for the first time.
