Abstract

A new compound, illiciumflavane acid (1), along with 13 known compounds (2-14), were isolated from the fruits of Illicium verum Hook. F. Their structures were elucidated through various spectroscopic methods, including 1D NMR ((1)H NMR, (13)C NMR), 2D NMR (HMQC, HMBC and NOESY) and HRMS. The stereochemistry at the chiral centres was determined using CD spectrum as well as analyses of coupling constants and optical rotation data. Cytotoxicity evaluation of four compounds showed that illiciumflavane acid and (E)-1,2-bis(4-methoxyphenyl)ethene exhibited potential against A549 activities with IC50 values of 4.63 μM and 9.17 μM, respectively.

Keywords: Illicium verum; cytotoxicity; illiciumflavane acid.
