More than 300 bio-active compounds have been identified from bee propolis in various regions of the world. The objective of this study was to examine whether the ethanol extracts of Chinese and Brazilian propolis may exert anticancer activities in four human colon carcinoma cell lines, namely CaCo2, HCT116, HT29 and SW480. Propolis samples were extracted with ethanol, and the crude extracts wer...

Propolis is a complex resinous material with many pharmacological and biological properties attributed to the presence of many volatile and non-volatile phytochemical compounds which have not been analysed in details for Malaysian propolis. In this study, we determined and compared volatile phytochemical compounds in water and ethanol extracts of Malaysian propolis (Trigona itama) using gas chr...

Streptococcus mutans triggers dental caries establishment by two major factors: synthesis of organic acids, which demineralize dental enamel, and synthesis of glucans, which mediate the attachment of bacteria to the tooth surface. Propolis is a natural product that may prevent dental caries. Baccharis dracunculifolia DC (Asteraceae), a native plant from Brazil, is the most important botanical o...

BACKGROUND/AIM Propolis is a bee product with antioxidative, antimutagenic, and other beneficial properties, and it is used as a natural drug. It is rich in polyphenolic compounds. Its composition varies depending on the particular geographical region. Oxidative stress is caused by an imbalanced free radical production and antioxidant system. The effects of flavonoids on the expression of DNA r...

Propolis extract antimicrobial activity against periodontopathic (ATCC) bacteria was investigated “in vitro”. Bacterial strains tested were: Prevotella intermedia, Prevotella melaninogenica, Porphyromonas gingivalis, Actinobacillus actinomycetemcomitans, Capnocytophaga gingivalis and Fusobacterium nucleatum. Minimal inhibitory concentration (MIC) for the strains tested was determined using the ...
