Although antioxidant activity and phenolic constituents of hazelnut (hazelnut kernel) [4,26-28] and some of its by-products [29-31,100] have been reported, little is known about phenolic phytochemicals and their potential health benefits in hazelnut and hazelnut by-products. Therefore, this chapter provides detailed information on nutraceuticals, phytochonicals, and health aspects of hazelnut and hazelnut by-products and evaluates their antioxidant activities by a number of indicators. Taxanes present in hazelnut by-products are discussed in detail. Where possible, the health benefits of relevant phytochemicals are described.

Phenolic compounds are important bioactive constituents derived from plants and are active ingredients in traditional medicine, pharmaceuticals, and nutraceuticals. Extraction process for phenolic acids requires standardization as within plant tissue they can stay either in the soluble fraction or as conjugates with carbohydrates or linked to cell wall components. HPLC is by far the most popular method of separation. Mass spectrometers, especially LC-MS and MALDI-TOF, provide a viable rapid and accurate method of identification and characterization of the simple phenolic acids. 

Details about structure, biosynthesis, and classification of phenolics are described in the other chapters in this handbook. Plant phenolics have a distinctive ability to form non-covalent, intermolecular complexes with each other and with both large and small molecules. Recognition of the antioxidant activities of many polyphenols has established correlation with the health benefits by such compounds [34]. This leads to the development of commercial products containing free-radical-scavenging phytochemical mixtures, for example, Pycnogenol (procyanidin extracted from Pinus maritima). Table 82.2 represents a list of polyphenolic compounds used in nutraceuticals and their biologic effects on human health.
