Abstract

Three new ent-kaurane diterpenoids, named pterokaurane M 1-M 3 ( 1- 3) and three new C 14 pterosin-sesquiterpenoids, named multifidoside A-C ( 4- 6), along with 18 known compounds, were isolated from the whole plants of Pteris multifida . The structures of 1- 6 were established using spectroscopic methods, including extensive 2D NMR and CD analyses. Compounds 4 and 5 showed cytotoxicity against the HepG2 tumor cell line with IC 50 values of less than 10 microM.
