Inhibition of Gluconeogenesis by Boldine in the Perfused Liver: Therapeutical Implication for Glycemic Control.

The alkaloid boldine occurs in the Chilean boldo tree (). It acts as a free radical scavenger and controls glycemia in diabetic rats. Various mechanisms have been proposed for this effect, including inhibited glucose absorption, stimulated insulin secretion, and increased expression of genes involved in glycemic control.

The food additive BHA modifies energy metabolism in the perfused rat liver.

A study of the effects of butylated hydroxyanisole (BHA) on the hepatic metabolism was conducted with emphasis on parameters linked to energy metabolism and mitochondrial reactive oxygen species production. The experimental systems were the isolated perfused rat liver and isolated mitochondria. It was found that BHA inhibits biosynthetic pathways (gluconeogenesis) and ammonia detoxification, which are dependent on ATP generated within the mitochondria.
