Quantification of major and some minor phenolic compounds in F1, F2 and F3 as determined by qHPLC.

ag/100 g refers to the amount of the compound present (g) in 100 g extract/fraction. bConcentration factor refers to the amount of a compound in a extract or fraction divided by the content of the compound in SM6Met for example mangiferin in F3 (11.57 g/1.90 g) = 6.09. cYield was calculated relative to the initial concentration of a compound in SM6Met, which was set to 100%. For example, for mangiferin in F3, the yield is (1.063 g/1.90 g) x 100 g = 55.96%, where 1.063 g (11.57 g x 9.19 g/100 g) refers to the total amount of mangiferin present in F3 as only 9.19 g of F3 is obtained during fractionation of 100 g SM6Met (as illustrated in S1 Fig). dRefers to peak number in qHPLC chromatogram in Fig 1. eNd—polyphenols were not detected due to absence or trace amounts fCo-elution refers to the fact that p-coumaric acid co-elutes with 3-hydroxyphloretin-3',5'-di-C-hexoside where present.
