Three new inositol angelate compounds (1−3) and two new tirucallane-type alkaloids (4 and 5) were isolated from the Amoora dasyclada, and their structures were established mainly by means of combination of 1D and 2D nuclear magnetic resonance and HR-ESI-MS. Based on cytotoxicity testing, compounds 4 and 5 exhibited significant cytotoxic activity against human cancer cell line HepG2 with IC50 value at 8.4 and 13.2 μM. In addition, compounds 4 and 5 also showed remarkable growth inhibitory activity to Artemia salina larvae.
