The production of flavour substances by cell or tissue cultures is still a dream for the future in most cases. Today the extraction of product from intact living plants is still less expensive than the production by isolated cells and tissues. On the other hand, it is very attractive to make use of the secondary metabolism of plant cells for the synthesis of natural flavours in a controlled way to avoid contaminating by-products and thus considerably simplify downstream processing. Further advantages of such cell culture systems would be the independence from agriculture combined with the risk for possible shortage and variances in product quality, the ability to scale-up the process to create an inexhaustible source of well-defined product.

Polyphenols are a heterogeneous group of natural compounds, particularly known for their beneficial effects on human health. In nature, polyphenols are produced by the secondary metabolism of plants, where, in relation to their various chemical characteristics have different roles ... 

Similar to polyphenols, alkaloids are products of the secondary metabolism of plants, which have been identified in hundreds of plant species with great structural diversity [21], Methybcanthines derived from purine nucleotides are known collectively as purine alkaloids. Caffeine, theophylline, and theobromine alkaloids are methylated xanthine derivatives. Figure 14.2 shows their chemical structures and, as can be observed, these structures differ only in the number and the position of one methyl substituent and/or hydrogen atom around the xanthine ring system.
