| | alpha-Angelica lactone Usage And Synthesis |
| Chemical Properties | α-Angelica lactone has a sweet, herbaceous odor reminiscent of tobacco. | | Chemical Properties | clear colorless to straw yellow liquid | | Occurrence | Reported found in grape, white bread, soy bean and licorice. | | Uses | alpha-Angelicalactone acts as acancer chemopreventive agent. It is used in the synthesis of glutathione and the activity of glutathione-S-transferase and UDP-glucunonosyltransferase detoxification enzymes in esophagus, stomach, intestine, and liver. It is used in oral care formulations to round out mint notes and in coffee flavors. | | Preparation | By dry distillation of levulinic acid | | Definition | ChEBI: Alpha-angelica lactone is an angelica lactone and a butenolide. It is functionally related to a but-3-en-4-olide. It is a tautomer of a beta-angelica lactone. | | Taste threshold values | Taste characteristics at 100 ppm: sweet, creamy, coconut, vanilla hay and coumarin-like nuances | | General Description | α-Angelica lactone, a cyclic lactone that occurs naturally in tobacco, is generally used in tobacco flavoring. | | Biochem/physiol Actions | Plant-derived cancer chemopreventive agent. Increases the synthesis of glutathione and the activity of glutathione-S-transferase and UDP-glucunonosyltransferase detoxification enzymes in esophagus, stomach, intestine, and liver. | | Safety Profile | Moderately toxic by ingestion andintraperitoneal routes. When heated to decomposition itemits acrid smoke and irritating fumes. |
