Abstract

Three new alkylated Chalcones, villosins A - C (1 - 3), five known analogues, together with ten known Coumarins, were isolated from Fatoua villosa. The structures of the new compounds were elucidated by extensive spectroscopic analysis, including 1D-, 2D-NMR, and MS data. Compounds 1 - 3 showed cytotoxicity against five kinds of human tumor cell lines (NB4, A549, SHSY5Y, PC3, and MCF7) with IC50 values ranging from 1.4 ± 0.1 to 5.7 ± 0.3 μm.
