Abstract

A new phthalide that was identified using NMR and mass spectral data as (±)-3-methoxysedanenolide (1) and the nine known compounds sedanenolide (2), Z-ligustilide (3), Z-butylidenephthalide (4), methyl ferulate (5), trans-ferulic (6) and trans-isoferulic acids (7), falcarindiol (8), β-sitosterol (9), and daucosterol (10) were isolated from the MeOH extract of roots of Ligusticum wallichii. Compounds 7 and 8 exhibited high inhibitory activity against NO formation in RAW264.7 cells.

Abstract

Two new acetophenone derivatives named knepachycarpanone A (1) and knepachycarpanone B (2) together with a new cardanol derivative named knepachycarpanol C (3) were isolated from the EtOAc extract of Knema pachycarpa stems. Their chemical structures were established on the basis of spectral evidences. Compounds 1 and 2 exhibited moderate cytotoxicity against Hela cancer cell line with IC50 values of 26.92 ± 1.46 and 30.20 ± 1.97 μM, respectively.
