ABSTRACT
For the last decades, a noticeable and ever-growing interest by millions of people worldwide in using foods containing concentrated sources of nutrients or supplemented with botanicals or botanical preparations deriving from plants have been observed. However, despite these constituents’ natural origin, there is also an increasing need to establish international rules concerning their quality and safety assessment. The development and validation of a great number of comprehensive analytical methods (including HPLC and related techniques) for accurate measurement of active or potentially toxic ingredients have turned out to be crucial for the realization of this purpose.
