It includes c. 130 species of trees, distributed in tropical lowland and submontane forests in tropical Asia, Australia and Melanesia. Previous studies have indicated that Goniothalamus shows a significantly higher diversification rate in comparison to closely related taxa and that its species diversity is the result of a relatively recent radiation.

In HL60 cells, GTN triggers mitochondria dysfunction, caspase activation and eventually, apoptosis. In this study, we demonstrated that GTN was able to induce apoptosis in hepatocellular carcinoma derived cells, SK-Hep1 and Hep-3B cells via upregulation of the phorbol-12-myristate-13-induced 1 (PMAIP1) protein , alternation of mitochondrial membrane potentials (P &amp

The cytotoxicity of GTN/cell viability was measured by MTT assay at 570-nm absorbance and the IC50 at 72 h were determined as 7.5, 17 mM in SK-Hep1 and Hep-3B respectively. The GTN induced cell death and accumulation of reactive oxygen species in HCC-derived cells.
