Terpenes and alkaloids are more potent toxins and also simpler compounds than polyphenols and for these reasons they are more often took seriously in the analysis platforms that neglect especially tanninsWide repertoire of analysis options for plant metabolitesAlthough our primary focus at the Natural Chemistry Research Group is with the analysis of tannins and other […]

Tannins have a number of functional properties in addition to their protein affinity and you should be able to choose the correct property to focus on, and it could guide you to find the most relevant defense compounds in your study plant Functional properties of plant samples may be linked to their bioactivityAlthough it is […]

The types and numbers of phenolic functional groups in tannins determine much of the bioactivities of individual tannins and now these functional groups can be analysed selectively compound by compound Traditional tannin methods have their limitationsThe more traditional types of tannin analyses rely on the quantitation of either tannin functional properties (e.g. protein precipitation capacity) […]

It is a nice idea to quantify tannins individually instead of measuring a less meaningful pool of total tannins, but to convince people to move from ideas to action requires that we create tools for the analysis of individual tanninsCan you use diode array detection to quantify individual compounds?In very specific cases it may be […]

Plants complicate the tasks of phytochemists by synthesizing hundreds of defense compounds in the plant cell and for that reason chromatographic methods are needed to yield less of a mess into the quantitative detectorWhy would you even try to analyse compounds individually?It is quite easy to reach such a consensus that the biological activity of […]
