precatorius agglutinin), carbohydrates (galactose, arabinose, and xylose), flavonoids (abectorin, dimethoxycentaureidin-7-o-rutinoside, and precatorin I, II, and III), anthocyanins (delphinindin, pelargonindin, and cyaniding), and alkaloids (dimethyl tryptophan, methocation, picatorine, abrine, hypaphorine, choline, and
trigonelline).
It was not just caffeine, but a mix of compounds including hydroxycinnamic acids notably chlorogenic acid,
trigonelline, diterpenes eg cafestol and kahweol, and caffeic acid, that is said to be the reason behind the link, said Mattias Carlstrom, Associate Professor from the Karolinska Institutet, Sweden.
A combination of coffee's compounds, including
trigonelline, cafestol, cafeic acid and chlorogenic acid, are thought to be important.
-A number of potentially clinically relevant compounds are present in coffee, including: caffeine, hydroxycinnamic acids notably chlorogenic acid,
trigonelline, diterpenes eg cafestol and kahweol, and caffeic acid ( ANI )
They also identified
trigonelline, a plant hormone, as the active component in Sakurajima Daikon that appears to promote a cascade of changes in coronary blood vessels resulting in improved nitric oxide production.-- IANS

Trigonelline: A compound with antibacterial properties.
According to the aforementioned authors, coffee belonging to species Robusta presents higher caffeine and chlorogenic acid levels and lower
trigonelline levels than coffee belonging to species Arabica.
Coffees of superior quality are those that have chemical compounds responsible for the flavor and aroma such as caffeine,
trigonelline, aldehydes, furans, ketones, sugars, proteins, amino acids, pyrroles, pyridines, pyrazines, oxazoles, carboxylic acids, fatty acids, and phenolic compounds in an equilibrated proportion to obtain good body, acidity, and smoothness of the beverage.
