Mangiferin was first isolated from the leaves and bark of
Mangifera indica (the
mango tree). It can also be extracted from
mango peels and kernels,
Iris unguicularis,
Anemarrhena asphodeloides rhizomes and
Bombax ceiba leaves. It is also found in the genera
Salacia and
Cyclopia, as well as in
coffee leaves and some species of
Crocus. 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. == Research ==
