Claim 0:
1. A method for making a caffeoylquinic composition, the method comprising:
i) contacting verba mate biomass, stevia biomass, or combinations thereof with a first aqueous composition comprising less than 30% (C1-C4)alkanol or free of (C1-C4)alkanol to obtain an initial extract;
ii) chromatographing the initial extract on an ion exchange stationary phase;
iii) eluting the stationary phase with a first aqueous elution composition comprising 10%-50% (C1-C4)alkanol to obtain a first eluent; and
iv) eluting the stationary phase with an acidified second aqueous elution composition comprising 60% to 80% (C1-C4)alkanol to obtain the caffeoylquinic composition,
wherein the caffeoylquinic composition comprises monocaffeoylquinic acid, dicaffeoylquinic acid, and salts of the foregoing; and
wherein the composition comprises less than 1% caffeine based on dry weight of the caffeoylquinic composition.
