Butein is a chalconoid. It can be found in Toxicodendron vernicifluum (or formerly Rhus verniciflua). It has antioxidative, aldose reductase and advanced glycation endproducts inhibitory effects. It is also a sirtuin-activating compound, a chemical compound having an effect on sirtuins, a group of enzymes that use NAD to remove acetyl groups from proteins.
