2 Diverse World of Natural Products Natural products are mainly focused on secondary metabolites derived or isolated from plants, terrestrial and marine organisms, bacteria and fungi. Natural products have been an important source for drug discovery and been used for the maintenance of health and well-being in the practice of traditional medicine throughout the world Waters Corporation 2
3 Natural Products = multiple-component mixture! Phenylpropanoids Alkaloids Terpenes Phenolics Glucosinolates Polyketides Terpenoids Can contain >1000s of unique compounds! Waters Corporation 3
4 Concerns in Natural Products NATURAL SAFE! Adulteration is a major concern with natural products in the market Deliberately substituted (financial incentive) Increase efficacy ~903 adulterated natural health products that have been detected in the industry! (US FDA) 2017 Waters Corporation 4
5 Liquid chromatography coupled with high resolution mass spectrometry LC-MS screening gained popularity with advent of electrospray ionization High sensitivity to detect low abundance compounds in extracts (nm sensitivity) Ability to detect multiple compounds without isolation Accurate mass screening What is Accurate Mass? Provides information on isotope ratios which can ensure the correct assignment of elemental composition Enables rapid determination of molecular formula for peak of interest Nominal Mass: CO = 28 N 2 = 28 C 2 H 4 = 28 Accurate mass: CO= N 2 = C 2 H 4 = ID of compounds 2017 Waters Corporation 5
