Compounds and Methods

Research on the molecular basis of photoexcitation and electron transfer, including interactions of electron donor and acceptor molecules, could lead to new photochemicals. Development of model photosensitive compounds and methods of incorporating them into membranes containing donor, acceptor, or intermediate excitation transfer molecules, and...

Color additives are naturally and synthetically derived. In the past 20 years, consumers have become increasingly aware of the ingredients in their foods and they desire foods be as natural as possible. This fact combined with technological developments have fueled the increases in uses of naturally derived colors. Moreover, additives must be safe and stable in food matfices. Legislation has established which colorants may be used as food additives, taking into account toxicity of compounds and methods of assessment. The European Union currently allows the use of 13 naturally derived colors but 26 colors are exempt from certification... 

Fig. 31.5. Biplot of 23 substituted chalcones (circles) and 8 chromatographic methods (squares) as described by their retention times in Table 31.2, after no transformation of the data. Areas of circles and squares are related to the mean retention times of the corresponding compounds and methods, such as they appear in the margins of the table.

The analysis of Table 31.2 by CFA is shown in Fig. 31.11. As can be seen, the result is very similar to that obtained by log double-centering in Figs. 31.9 and 31.10. The first latent variable expresses a contrast between NO2 substituted chalcones and the others. The second latent variable seems to be related to the electronic properties of the substituents. The contributions of the two latent variables to the total inertia is 96%. The double-closed biplot of Fig. 31.11 does not allow a direct interpretation of unipolar and bipolar axes in terms of the original data X. The other rules of interpretation are similar to those of the log double-centered biplot in the previous subsection. Compounds and methods that seem to have moved away from the center and in the same directions possess a positive interaction (attraction). Those that moved in opposite directions show a negative interaction (repulsion).

In the previous chapters we have discussed the different classes of phenolic compounds, their chemical properties, and their biosynthesis. The characterization of phenolic compounds relied on the ability to isolate them from plant tissues. In this chapter we will discuss methods to isolate and characterize phenolic compounds, and methods to visualize them in planta. Chapter 5 focuses on techniques for the identification and characterization of some of these compounds using recently developed mass-spectrometry-based techniques.

The originality of this present edition lies in a comprehensive presentation of the modem concepts of PolyP biochemistry, including a comparative description of PolyP metabolism in prokaryotes and eukaryotes, i.e. the role of these compounds in the cells of organisms at different stages of evolution, and offers a critical analysis of the methods of isolation and quantitative assessment of these compounds and methods of studying PolyP-dependent enzymes. The contemporary literature on these problems is presented to its maximal extent. The book may therefore serve as a manual for researchers in this field, and in particular, as a textbook. 

Methods 1 and 2 were used for water-soluble compounds, and methods 3 and 4 were used for oil-soluble compounds.
