nodakenin/カワラボウフウ属

OBJECTIVE To establish a HPLC method to determine the contents of nodakenin in Peucedanum. METHODS The determination method was achieved by RP-HPLC on an ODS column by UV detection at 334 nm; with nodakenin as external standard and H2O-CH3OH-CH3CN(75:5:20) as mobile phase. RESULTS Several samples of

Two new compounds, decuroside VI (1) and decursidate (2), were isolated from the roots of Peucedanum decursivum. Their structures were elucidated as 6'-O-crotonyl-nodakenin and 2-[4'-hydroxyphenyl]-glycol mono trans-ferulate on the basis of spectral analyses and chemical methods.
