Bee pollen is considered as one of the functional foods due to its complex biochemical
properties. Bee pollen which is collected from pollen grains from various botanical sources
contains almost a complete nutrition such as carbohydrates, proteins, amino acids, vitamins
and minerals. Its beneficial effect on health is thought to be due to the presence of phenolic
compounds with its antioxidant activity. Antioxidant activities of ethanolic bee pollen extract
(BPE) from three species of Malaysian stingless bee; Trigona thoracica, Trigona itama and
Trigona apicalis in this study were measured using DPPH-HPLC method and gallic acid (GA)
as a standard reference. The percentage of DPPH inhibition by T. apicalis BPE at 1 mg/mL
showed the highest inhibition (39%, GA equivalent to 0.3 mg/mL) compared with T. itama
(14.3%, GA equivalent to 0.1 mg/mL) and T. thoracica (6.7%, GA equivalent to 0.05 mg/mL).
Our result was the first in reporting antioxidant activity of BPE measured using DPPH-HPLC
method from three different species of Malaysian stingless bee.
