Angelica root is one of the common plants that have been used widely in traditional medicine. The main active ingredients of Korean angelica root are known for decursin and decursinol angelate. These components are converted to decursinol in the human liver. Also, butylphthalide and Z-butylenephthalide are found in Korean angelica. In a study, pyranocoumarin is detected as the most abundant principle with decursin and decursinol angelate. These active ingredients showed inhibition activity to metastatic prostate cancer cells and cervical cancer cells. Also, some scientific studies revealed that Korean angelica root extract has anti-inflammatory and anti-oxidant effects.
