“…Interesting results were also published by Suleman and colleagues [51]. Some of 39 South Africa propolis samples exhibited much higher antistaphylococcal activity in comparison to three tested samples of Brazilian propolis with MIC and MBC values of only 6 μg/mL [51]. Al-Waili and coworkers revealed that ethanolic extracts of propolis collected from Saudi Arabia (EEPS) and from Egypt (EEPE) efectively inhibited the growth of antibiotic resistant E. coli, S. aureus and C. albicans in single and polymicrobial cultures [52].…”

Bacteria of the genus Staphylococcus are important human and veterinary pathogens. A crucial characteristic for this group of bacteria is that they can easily acquire mechanisms of antibiotic resistance for a plethora of antibiotics currently in use for human and animal therapies. Therefore, there is a great need to ind novel, non-antibiotic chemotherapeutics with marked antistaphylococcal activity. Promising but still underestimated group of potential antistaphylococcal chemotherapeutics constitute bee products: honey, pollen, royal jelly, fermented pollen and especially propolis. Another group of natural products that exhibit promising antibacterial activity is essential oils. Usefulness of bee products and essential oils in the treatment of infections caused by S. aureus has been conirmed by results of many investigations carried out by researches in diferent regions of the world. In this chapter, we have presented the review of publication in this area as well as perspectives and limitations of future applications of these two groups of natural products.

“…In a search for new antimicrobials Suleman, van Vuuren, Sandasi, and Viljoen () examined extracts from propolis, a sticky resin found in beehives, by LC‐MS, chemical analyses, and bioassays. The data were evaluated using multivariate data analysis by orthogonal projections to latent structures (OPLS) and an S‐plot function.…”

In the last decade, the use of multivariate statistical techniques developed for analytical chemistry has been adopted widely in food science and technology. Usually, chemometrics is applied when there is a large and complex dataset, in terms of sample numbers, types, and responses. The results are used for authentication of geographical origin, farming systems, or even to trace adulteration of high value-added commodities. In this article, we provide an extensive practical and pragmatic overview on the use of the main chemometrics tools in food science studies, focusing on the effects of process variables on chemical composition and on the authentication of foods based on chemical markers. Pattern recognition methods, such as principal component analysis and cluster analysis, have been used to associate the level of bioactive components with in vitro functional properties, although supervised multivariate statistical methods have been used for authentication purposes. Overall, chemometrics is a useful aid when extensive, multiple, and complex real-life problems need to be addressed in a multifactorial and holistic context. Undoubtedly, chemometrics should be used by governmental bodies and industries that need to monitor the quality of foods, raw materials, and processes when high-dimensional data are available. We have focused on practical examples and listed the pros and cons of the most used chemometric tools to help the user choose the most appropriate statistical approach for analysis of complex and multivariate data.

“…Nevertheless, research on propolis in sub-Saharan Africa has shown that, in general, African propolis -like the propolis found in other tropical regions -is rich in terpenoids, including α-amyrine, β-amyrin, α-amyryl acetates, β-amyryl acetates, n-alkanes, n-alkenes, methyl n-alkanoates, and long-chain wax esters, among other compounds. [25][26][27][28][29][30] The price of propolis varies according to its source and quality. For example, Chinese propolis is offered for sale at about €25 to €50 euros per kg, while the Brazilian propolis is offered at higher prices (€100 to €150 euros per kg).…”

Background: Honey, pollen, and propolis are among the products that bees process and derive from plants and flowers. Propolis is a resinous material that bees gather from the buds and bark of some trees and small plants. Propolis from temperate climates mainly contains phenolic compounds, in contrast with propolis from tropical climates, which mainly contains terpenes. This study aimed to determine, characterise, and quantify the phenolic content of raw propolis from Burundi. Methods: In this study, a total of 6 samples were collected from the provinces of Rumonge, Cibitoke, and Ruyigi in Burundi. Fifteen phenolic compounds (caffeic acid, ferulic acid, epigallocatechin gallate, isoferulic acid, cinnamic acid, caffeic acid phenethyl ester, gallic acid, apigenin, chrysin, galangin, quercetin, kaempherol, rutin trihydrate, naringenin, and pinocembrin) were used as high-performance liquid chromatography (HPLC) standards for qualitative and quantitative analyses of the propolis samples. Results: Among the 15 phenolic compounds checked, only 1 -gallic acid -was detected at a measurable level using an HPLC-diode array detector system. Conclusion: In addition to terpenes, propolis found in sub-Saharan Africa may contain phenolic compounds. Further advanced investigation of sub-Saharan African propolis is required for more detailed characterisation.
