Abstract:
Five new degraded diterpenoids trigoxyphins J-N (1-5), among them trigoxyphins K and L have a novel carbon skeleton, together with four known analogues (6-9) have been obtained from the ethanol extract of the twigs of Trigonostemon xyphophylloides. Compounds 1-5 were evaluated for their cytotoxic activity in vitro against three human tumor cell lines by MTT assay. The results exhibited that Trigoxyphin N (5) showed moderate cytotoxicities against SPC-A-1 and SGC-7901 cancer cell lines.
