Quantification of major and some minor phenolic compounds in SM6Met, PF and NPF as determined by qHPLC.

<p>^ag/100 g refers to the amount of the compound present (g) in 100 g extract/fraction.</p><p>^bConcentration factor refers to the amount of a compound in an extract or fraction divided by the amount of the compound in SM6Met. For example, for mangiferin in the PF the concentration factor is (0.09 g/1.90 g) = 0.05.</p><p>^cYield was calculated relative to the initial concentration of a compound in SM6Met, which was set to 100%. For example, for mangiferin in the PF, the yield is (0.061 g/1.90 g) x 100 = 3.22%, where 0.061 g (0.09 g x 67.9 g/100 g) refers to the total amount of mangiferin present in the PF as only 67.9 g of the PF is obtained during fractionation of 100 g SM6Met (as illustrated in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0132950#pone.0132950.s001" target="_blank">S1 Fig</a>).</p><p>^dRefers to peak number in qHPLC chromatogram in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0132950#pone.0132950.g001" target="_blank">Fig 1</a>.</p><p>^eNd—polyphenols were not detected due to absence or trace amounts.</p><p>^fco-el—Co-elution refers to the fact that <i>p</i>-coumaric acid co-elutes with 3-hydroxyphloretin-3',5'-di-<i>C</i>-hexoside.</p><p>Quantification of major and some minor phenolic compounds in SM6Met, PF and NPF as determined by qHPLC.
