Identification and screening of cultivars rich in bioactive phytoconstituents can be potentially useful to make nutrient-dense dishes and in medicinal formulations. In this study, we have identified, characterized and quanti‑ fed caffeoylquinic acids, dicafeoylquinic acid, dicafeoyltartaric acid, kaempferol conjugates, quercetin malonylglu‑ coside, sesquiterpene lactones. | Identification and quantification of selected metabolites in differently pigmented leaves of lettuce Lactuca sativa L. cultivars harvested at mature and bolting stages
