From the ethyl acetate extract of Nageia wallichiana, collected in Lam Dong province, Vietnam four diterpenoids with the abietane skeleton and one nor-diterpene dilacton have been isolated. Their structures were elucidated by using combined spectroscopic methods as IR, MS and NMR. The cytotoxic activity of three of five compounds against 8 human cancer cell lines has been evaluated. The nor-diterpene dilactone showed strong activity on all tested cancer cell lines. This is the first report on the chemical constituents and the cytotoxic activity of Nageia wallichiana.
Keywords. Diterpenoids, nor-diterpene dilactone Nageia wallichiana, cytotoxicity.
