In chemistry, a derivative is a compound that is derived from a similar compound by some chemical or physical process (Source: Wikipedia), while in biodiversity related context derivatives refer to products of any biotic component of ecosystems, in particular genetic resources, with actual or potential use or value for humanity (Source: based on CBD, Art. 2). The Nagoya protocol defines a derivative as 'a naturally occurring biochemical compound resulting from the genetic expression or metabolism of biological or genetic resources, even if it does not contain functional units of heredity' (Source: Nagoya Protocol, Art. 2)
