In its green form both Arabica and Robusta coffee contain on average 15-17% and 10-11.5%, respectively. The chemical and physical changes that happens during the extraction is also addressed. Contents 1 Overview 2 Groups 2.1 Acids and anhydrides 2.2 Alkaloids 2.3 Alcohols 2.4 Amines 2.5 Esters 2.6 Ketones 2.7 Organosulfuric compounds 2.8 Phenols Chlorogenic Acid These compounds account for up to 8% of the composition of unroasted coffee beans. It starts to decompose at 160C so in the roasting process (which is hotterup to 200C), more than half the trigonelline is lost, in the process producing aromatic compounds that create sweet, caramel and earthy aromas. The amount of these will vary according to the quality of the green coffee - but remember that the chemical composition of green beans is entirely different from that of roasted beans. Depending on where the coffee came from, how it was processed, and how it was roasted, these compounds may or may not be present in your cup and may differ in quantity.
