-"Lactuca sativa was first known in cultivation in ancient Egypt. It is widely cultivated as a vegetable in China. Leaves of the species contain Vitamins A, B9, C, and K and can be eaten as a salad. Lactuca sativa has many cultivars, which are usually treated as varieties. Lactuca sativa var. angustata Irish ex Bremer is the most commonly cultivated variety in China, where the thick stems are cooked as a vegetable.[[http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=200024117]]+"Lactuca sativa was first known in cultivation in ancient Egypt.

 Bitterness of lettuce is associated with sesquiterpene lactones and its derivatives like lactucin-15-oxalate, 8-deoxylactucin 15-oxalate and lactucopicrin oxalate. Tannins based on 4-hydroxyphenyl acetyl esters of glucose with 2,3,4-tri-O-(4-hydroxyphenylacetyl)glucopyranose and homologues as core components are also present. \\ Bitterness of lettuce is associated with sesquiterpene lactones and its derivatives like lactucin-15-oxalate, 8-deoxylactucin 15-oxalate and lactucopicrin oxalate.
