Figure 3

Phenylpropanoid concentrations in tubers from six locations measured by HPLC. (a) chlorogenic acids with levels of CCGA and C4CGA in the inset. (b) aromatic amino acids, glycoalkaloids and ascorbate. (c) caffeic acid, feruloyl derivatives, polyamines. CGA, chlorogenic acid; cCGA, crypto chlorogenic acid; nCGA, neochlorogenic acid; C4CGA and C5CGA, chlorogenic acid isoform; FAQ1 and FAQ2, feruloylquinic acid isoforms; CA, caffeic acid; CAP, caffeoylputrescine; TDCSD, tris-dihydrocaffeoyl spermidine; BDCSD, bis-dihydrocaffeoylspermidine; BDCS, bis-dihydrocaffeoylspermine; TDCS, tris-dihydrocaffeoyl spermine; Tyr, tyrosine; Phe, phenylalanine; Trp, tryptophan; GA, glycoalkaloids; Asc, ascorbate. Refer to 2nd Y-axis for CA, BDCS, and TDCS. The data represents the means ± SE of three biological replicates. Locations with same letter are not significantly different (p < 0.05)
