Chicory root contains some phytochemicals such as inulin (starch-like polysaccharide), coumarins, flavonoids, sesquiterpene lactones (lactucin and lactucopicrin), tannins, alkaloids, vitamins, minerals, and volatile oils .
High quantities of sesquiterpene lactones, such as lactucin, 8-deoxylactucin, lactucopicrin, and 11fi-dihydro-derivatives, are hugely responsible for their bitterness .
) The alkaloid and lactucin
isolated from the seeds exhibited antipyretic activity, and a triterpenoid saponin isolated from the stem had antibacterial activity.
Chemical compounds of chicory are water, proteins, lipids, carbohydrates, calcium, phosphorous, iron, potassium, thiamine, riboflavin, niacin, glucoside, chicoriin, a resin called chicoridine, ascorbic acid, copper, mucilage, essence, pectin, lactucin
, intibin, arsenic, vitamin A, and vitamin B .
Lettuce's anti-inflammatory effects make it a good topical remedy for simple sprains and strains, says Brigitte Mars, author of "The Desktop Guide to Herbal Medicine." You might want to nibble a few leaves, too: "Lettuce is rich in lactucin
, a calming alkaloid," says Mars.
If you're eating in the evening, include a good portion of lettuce, which contains sleep-inducing lactucin
For example, sap from Lactuca canadensis has been found to contain the guaianolides lactucin
and lactucopikrin (Gonzalez, 1977).
Indeed, chicory root is known for its bitter taste, which is essentially due to STL, mainly lactucin (Lc) and lactucopicrin (Lp) [10,11].
11(S), 13-Dihydrolactucin (DHLc), lactucin (Lc), 11(S),13-dihydrolactucopicrin (DHLp), and lactucopicrin (Lp) were provided by Extrasynthese (Genay, France); 11(S),13-dihydro-8-deoxylactucin (DHdLc) and 8-deoxylactucin (dLc) were extracted, purified in the laboratory from industrial chicory root, and authenticated by [sup.1]H nuclear magnetic resonance (NMR) and 13CNMR 19] (Figure 1).
