TL;DR: The basis of ionization and the concepts of the most promising ambient MS techniques known to date are described and compared and illustrated, via typical analytical and bioanalytical applications, how ambient MS is helping to bring MS analysis deeper than ever into the “real world” open atmosphere environment—to wherever MS is needed.

TL;DR: Organic extracts from yerba maté, both green and roasted, and from green tea showed excellent DPPH scavenging activity and ethanolic extracts with lower content of phenolic compounds presented high antioxidant activity, even at very low phenolic concentrations.

TL;DR: An overview of the available methods for studying propolis in different aspects is given in this article, where the authors give an overview of different aspects of propolis, such as propolis production in the bee colony, chemical composition and plant sources, biological activity, and standardization and quality control for industrial application.

TL;DR: The results indicated that the highest yield of propolis extracts obtained by maceration, which also had the greatest number of components, were those using 70% (v/v) ethanol or more as a solvent as mentioned in this paper.

TL;DR: An improved approach for the direct infusion electrospray ionization mass spectrometry (ESI-MS) analysis of vegetable oils is described and fingerprinting analysis was applied to genuine samples of olive, soybean, corn, canola, sunflower, and cottonseed oil.
