Mangiferin

Mangiferin is a xanthonoid. This molecule is a glucoside of norathyriol.

It is found in mangoes, in Iris unguicularis, Anemarrhena asphodeloides rhizomes, and in Bombax Ceida. It is also found in the genera Salacia and Cyclopia.

Among the group of Asplenium hybrids known as the "Appalachian Asplenium complex", mangiferin and isomangiferin are produced only by Asplenium montanum and its hybrid descendants. The distinctive gold-orange fluorescence of these compounds under ultraviolet light has been used to aid in the chromatographic identification of hybrid Aspleniums.
