Because of the scarcity and expense of natural vanilla extract, synthetic preparation of its predominant component has long been of interest. It is also reported to be present in elderberry juice, blueberries, orange juice, strawberries, passion fruit juice, leeches, and wines. The most popular of those methods begins with eugenol ((C3H5)C6H3(OH)OCH3) or isoeugenol ((CH3CHCH)C6H3(OH)OCH3).

Vanilla was probably first used as a flavoring by the inhabitants of South and Central America before the arrival of Europeans in the sixteenth century. The fingerprint region for protocatechualdehyde was found to be at 1710.2 cm-1 which matches with the standard for -C=O stretch for aromatic aldehyde as shown by the IR correlation tables. It may be possible that the enzymes will perform some other vital functions which will interfere with vanillin production.7. That waste material consists primarily of lignin, a complex natural polymer that, along with cellulose, is the primary component of wood. VanillinHCl staining can be used to visualize the localisation of tannins in cells.

There's a safety reason and a practical reason., Vanillin is mostly insoluble in water but soluble in aqueous sodium hydroxide solution? Caffeic acid then undergoes methylation by caffeic acid O-methyltransferase (COMT) to give ferulic acid. To this solution 0.5 ml of diethyl ether was added dropwise under vigorous stirring during 1 hour at a temperature of 55-60oC.
