Anti-staphylococcal activity of C-methyl flavanones from propolis of Australian stingless bees (Tetragonula carbonaria) and fruit resins of Corymbia torelliana (Myrtaceae).
Ethanolic preparations of propolis were shown to be active against Staphylococcus aureus and to a lesser extent against Pseudomonas aeruginosa and C. torelliana flavanones inhibited the growth of S. aureu therefore contributing to the antibacterial effects observed for Australian stingless bee propolis extracts.

Diversity matters: how bees benefit from different resin sources
It is found that resin diversity is beneficial for bees, with its functional properties depending on the target organisms, type and composition of resin, and resins of different plant species target different organisms and act synergistically where combined. Expand
In vitro antibacterial phenolic extracts from "sugarbag" pot-honeys of Australian stingless bees (Tetragonula carbonaria).
Australian stingless bee honeys have been shown to exert antioxidant and in vitro antimicrobial properties; however their bioactive factors remained unidentified. This study investigated theExpand
Phloroglucinols from Anti‐Microbial Deposit‐Resins of Australian Stingless Bees (Tetragonula carbonaria)
The diagnostic data enabled the identification of markers that can be used for profiling other Australian propolis sources and to target the isolation of bioactive phloroglucinols in future studies against antibiotic resistant S. aureus strains. Expand
Chemical composition and antimicrobial activity of honeybee (Apis mellifera ligustica) propolis from subtropical eastern Australia
The antistaphylococcal potential of propolis was discussed, also in relation to honeybees’ health, as it warrants further investigations on the social and individual immunities of Australian honeybees. Expand
In Vitro Antibacterial Phenolic Extracts from “Sugarbag” Pot-Honeys of Australian Stingless Bees (Tetragonula carbonaria)
This study investigated the antibacterial properties of phenolic extracts from Tetragonula carbonaria honeys, harvested from beehives in three sites of South East Australia, and found them to contain the bactericidal effects of hydrogen peroxide. Expand
Characterization of Synthetic and Natural Product Pharmaceuticals by Functional Group Analysis using Electrospray Ionization-Ion Trap Mass Spectrometry: A Mini-Review
This mini-review is concerned with the characterization of synthetic and natural product pharmaceuticals by functional group analysis using electrospray ionization-ion trap mass spectrometry. StudiesExpand
Metabolomics analysis of pot-pollen from three species of Australian stingless bees (Meliponini)
Pot-pollen from Australian stingless bees (Meliponini) was analysed for volatile organic compounds (VOCs) and secondary metabolites from ethanolic extracts, including traces of secondary metabolites typical of stingless bee propolis. Expand
Bioactivity and Botanical Origin of Austroplebeia and Tetragonula Australian Pot-Pollen
Antibacterial properties, antioxidant activity, and bioactive components were measured in ethanolic and methanolic extracts of pot-pollen from Australian stingless bees (Meliponini) AustroplebeiaExpand
