Artichoke leaf extract - Recent findings reflecting effects on lipid metabolism, liver and gastrointestinal tracts.

In various molecular, cellular and in vivo test systems, artichoke (Cynara scolymus L.) leaf extracts show antioxidative, hepatoprotective, choleretic and anti-cholestatic effects as well as inhibiting actions on cholesterol biosynthesis and LDL oxidation. Recently active ingredients responsible for the main effects have been identified. Thus, luteolin seems to be of crucial importance for the inhibition of hepatocellular de novo cholesterol biosynthesis. The anti-dyspeptic actions ware mainly based on increased choleresis. Regarding clinical data, lipid-lowering, antiemetic, spasmolytic, choleretic and carminative effects have been described, along with good tolerance and a low incidence of side effects. Due to its specific mechanisms of action, the future use of artichoke leaf extract for the prevention of arteriosclerosis can be expected.
