    Notes: Capillary gas chromatography was used to obtain high resolution profiles of 27 organic acids, caffeine, and sucrose in dimethylsulfoxide extracts of roast and ground coffees in a sixty-minute analysis. A shortened procedure was also reported for the quantitative determination of S-caffeoylquinic (SCQA) and quinic (QA) acids and sucrose. Nanogram detection limits were achieved and the reproducibility of the method was under 5% relative. Major, commercial brands of caffeinated and decaffeinated coffee produced under different roasting conditions could be distinguished based on their 5-CQA and sucrose content and on the ration of QA-to-SCQA.
