Abstract
Near infrared spectroscopy (NIRS) and UV/Vis spectrophotometric methods were investigated as
rapid and/or more economical methods to quantify the major monomeric phenolic compounds,
soluble solid content (SSC), total polyphenol content (TPC) and total antioxidant activity (TAA) of
green rooibos and Cyclopia genistoides.
