OBJECTIVE: To study the chemical constituents in roots of Peucedanum praeruptorum. METHOD: The constituents were isolated by column chromatography on silica gel and ODS, and identified by MS spectroscopic methods including NMR and. RESULT: Seven compounds, acetylatractylodinol (I), tanshinone II A (II), tanshinone I (III), cis-3', 4'-diisovalerylkhellactone(IV), cis-3',4'-disenecioylkhellactone(V), (+)praeruptorin B(VI), and beta-sitosterol(V), were isolated and identified. CONCLUSION: Compounds I, II, III, IV were isolated from this plant for the first time.
