HPLC chromatograms of cinnamon bark extract.

(a) HPLC chromatogram of cinnamon bark extract: Top panel shows detection of trans-cinnamaldehyde. Bottom panel shows larger version of the area indicated by the red arrow in top panel, showing 2, A-type procyanidin (PC) dimer; 3, A-type PC trimer; 5, A-type PC trimer; 6, internal standard; 7, cis—Cinnamic acid; 9, trans—Cinnamic acid. (b) HPLC chromatogram of thiolysed cinnamon bark extract (BM = benzylmercaptan adduct): 1, Catechin; 2, A-type PC dimer; 3, A-type PC trimer; 4, Epicatechin; 5, A-type PC trimer; 6, Internal standard; 7, cis—Cinnamic acid; 8, A-type PC—BM trimer; 9, trans—Cinnamic acid; 10, cis Catechin—BM; 11, Epicatechin—BM; 12, A-type PC—BM dimer.
