Tangeretin is an O-polymethoxylated flavone that is found in tangerine and other citrus peels. Tangeretin strengthens the cell wall and acts as a plant's defensive mechanism against disease-causing pathogens.[2]

It has also been used as a marker compound to detect contamination in citrus juices.[2]

The following is a list of methods used to extract tangeretin from citrus peels:

  • column chromatography
  • preparative-high performance liquid chromatography
  • super critical fluid chromatography
  • high speed counter current chromatography
  • a combination of vacuum flash silica gel chromatography and flash C8 column chromatography
  • flash chromatography

However, methods for tangeretin extraction are currently being tested to maximize efficiency and percent yields as its uses in treatment of cancer and other diseases are becoming better understood.[2]

Tangeretin is commercially available as a dietary supplement.
