Figure S1. Chemical structure and intestinal degradation of anthocyanidin glycosides (= anthocyanins) present in bilberry pomace extract (BE). Bilberry anthocyanidins are either linked to glucose, galactose or arabinose in 3-O position, respectively. PGA: Phloroglucinol aldehyde [9-11].

Figure S2. Ileostomy fluid anthocyanin quantities after consumption of 10 g bilberry pomace extract (BE). Anthocyanin time courses of the five individual ileostomy probands were quantified by HPLC-UV/VIS analysis as cy-3-glc equivalents. Values are means ± SD of three determinations.
