ABSTRACT
AIM To study the chemical constituents of Peucedanum decursivum. METHODS Various column chromatographies with silica gel and HPLC were employed for the isolation and purification. The structures of the compounds were elucidated on basis of spectral analyses and chemical methods. RESULTS Seven compounds were isolated from the roots of Peucedanum decursivum (Miq.) Maxim. 1 is 3′(S)-hydroxy-4′(R)-angeloyloxy-3′,4′-dihydroxanthyletin, named Decursitin D; 2 is 3′(S)-acetoxy-4′(R)-hydroxy-3′,4′-dihydroxanthyletin, named decursitin F; the others are 3′(S)-acetoxy-4′(R)-angeloyloxy-3′,4′-dihydroxanthyletin (3), Pd-C-IV (4), Pd-C-II (5), (+)-3′S-decursinol (6) and (+)-trans-decursidinol (7). CONCLUSION Compounds 1 and 2 are new compounds, while compounds 6 and 7 were isolated from Peucedanum decursivum (Miq.) Maxim for the first time.
