摘要: From the root tubers of Lactuca tuberosa, a wild edible plant species, nine phenolic compounds were isolated, including two new furofuran lignan glucosides, named lactuberin A and B. Their structures elucidated by spectroscopic methods, especially HRESIMS 2D NMR techniques. This is first time that belonging to epi series 2,6-diaryl-3,7-dioxabicyclo[3.3.0]octane type lignans have been found in species. The total content tuber extract was evaluated its major constituents, caffeic acid, chlorogenic acid 3,5 dicaffeoylquinic known possess antioxidant activity, quantified. Additionally, showed DPPH radical scavenging activity implying potential as functional food.
