Comparison of two-step condensed tannin quantification using butanol-HCl assays with or without acetone. Points represent concentrations of soluble or insoluble CTs, or the sum of both two forms (Sol + Insol CT). Sample to solvent concentrations were ~1 mg ml−1 for the protocol without acetone, and 5–20 mg ml−1 for the acetone containing protocol. Top, middle and bottom equations correspond to soluble, insoluble, and soluble + insoluble CT quantifications
