Abstract
Propolis is a gum-like product that collected by bees from plants and it varies in colour range from light yellow to dark brown. The chemical composition of propolis dependson various factors such as vegetation, season and environmental conditions of the sample collection. The aim of the study was to determine the chemical profile and antioxidant properties of crude methanol extract of Geniotrigona thoracicapropolis from five localities, namely Besut (BST), Dungun (DGN), Lundang (LDG), Tanah Merah (TM) and Gua Musang (GM). Phytochemical screening by thin layer chromatography (TLC) showed the presence of terpenoids, flavonoids, coumarins, essential oils and unsaturated and aromatic compounds. The extracts displayed different characteristics of chemical profile that varied from each other. The antioxidant properties of extracts were evaluated based on total phenolic content, total flavonoid content and 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical-scavenging activity. Propolis from Gua Musang (GM) exhibited the highest total phenolic content with 23.43 ± 0.50mg GAE/gextract while propolis from Besut (BST) exhibited the highest total flavonoids content with 17.22 ± 0.16mg QE/gextractand showed the lowest IC50with 53 μg/mL for DPPH radical scavenging activities. As a result, geniotrigona thoracica from Besut (BST) could be considered as a good source of antioxidant due to its antioxidant properties.
