CGA is currently extracted from various plant materials, particularly green coffee beans. Yerba mate ( Ilex paraguariensis  St. Hil.) contains significant amounts of CGA with very low levels of extraction interfering substances (fatty materials). Both of these reasons prompted us to evaluate yerba mate as a novel source for extraction of this compound.  CGA content was quantified in various yerba mate fractions during different processing steps, and in samples taken from two companies at early and late harvesting seasons. Samples were exhaustively extracted with hot water and total CGA content (including its three isomeric compounds) was determined by HPLC. Total CGA content (on a dry weight basis) ranged from 45.8 ± 0.4 to 80.8 ± 1.0 g CGA kg −1  of leaves and from 31.6 ± 0.6 to 78.9 ± 5.3 g CGA kg −1  of stems. A substantial reduction in CGA content was found along the processing steps. The highest CGA content was found in samples from freshly harvested (green) yerba mate, for both leaves and stems; with no significant differences in their CGA content ( P   Green stems, a residue from yerba mate processing obtained at the early harvesting season, could be considered as a promising and valuable raw material for the production of CGA-enriched extracts."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380567182197243139","@type":"Researcher","foaf:name":[{"@value":"Ana P.
