There are relatively few publications on oleuropein concentrations in cultivars particular to the South of France where the most common varieties include Picholine, Lucques, Verdale and Negrette. There are no publications on Olivière, another variety widely found in the Languedeoc Region of France. In probably the most relevant publication to this study Savournin et al. found that among 14 different olive cultivars, the mean concentration of oleuropein in Picholine leaves was 11.7 *% (w/w), the amount being 13.4 and 10.5 % (w/w) for Lucques and Verdale, respectively .
