Studying of flavonoids of romaine lettuce

Abstract

Lettuce is a single vegetable. It belongs to the Aster family(Astraceae L.), subfamily – Cichorideae, genus - Lactuca, species - Lactuca sativaL.The main varieties include iceberg, romaine and various leaf varieties. Lettuce is oneof the most widely consumed vegetables in the world, but its nutritional value isunderestimated. Lettuce leaves are a good source of biologically active compounds for humanhealth. It is rich in fiber, macro- and microelements, vitamins (folic and ascorbicacid). Lettuce is low in calories, fat, and sodium. However, the composition ofnutrients and biologically active compounds differs in different varieties of lettuceand has not been studied enough. Therefore, we chose romaine lettuce (Lactucasativa var. romana Lam.) for a more detailed phytochemical study.
