In apoptosis assay, at concentration of 14 μgmL-1 (IC50), there were 44.84% of cell undergoes early apoptosis while 38.81 % was viable cell. Overall, data from this study shown that propolis collected form university’s apiary (HI-BST) is the best quality propolis compare to other location.

Propolis is a resinous mixture collected from stingless bees and is reported to have various biological activities such as antioxidant, antibacterial, antitumor and hepatoprotective. Location where bees were bread plays an important role in determining the types and quality of propolis.
