		relative percentage (%)^a
Rt (min)	compound	70 °C	100 °C
12.32	1H-imidazole	1.58	4.51
14.21	4-methyl-1H-imidazole	0.00	43.07
20.47	4-(hydroxymethyl)-1H-imidazole	67.42	46.45
28.38	4-(dihydroxyethyl)-1H-imidazole	1.58	5.64
34.93	4-(2,3,4-trihydroxybutyl)-1H-imidazole	6.09	44.87
35.41	4-(arabino-tetrahydroxybutyl)-1H-imidazole	834.99	74.41
35.80	2-acetyl-4-(tetrahydroxybutyl)-1H-imidazole	0.45	7.22

Values were calculated as ratio of the peak areas of the analytes relative to the internal standard phenylglucoside.
