Propolis Extracted from the Stingless Bee Trigona sirindhornae Inhibited S. mutans Activity In Vitro.

Purpose: The aim of this study was to determine the antimicrobial effects of propolis extracted from an endemic species of stingless bee, T. sirindhornae, on the cariogenic bacterium Streptococcus mutans.

Materials And Methods: Dichloromethane extracts (DME) of propolis (DMEP) were prepared and analysed by reverse-phase high-performance liquid chromatography.

Cytotoxic Activity of Propolis Extracts from the Stingless Bee Trigona Sirindhornae Against Primary and Metastatic Head and Neck Cancer Cell Lines.

Background: Propolis, a resinous substance produced by the honeybee, has a wide spectrum of potent biological activities. However, anti-cancer activity of propolis obtained from Trigona sirindhornae, a new species of stingless bee, has not yet been reported. This study concerned cytotoxicity of propolis extracts from T.
