Gamboge 藤黄(to-o): A yellow-orange gum-resin produced by several species of Garcinia tree found in India, Thailand, Cambodia, Vietnam, and Ceylon. Gamboge was used as a yellow pigment as early as the 8th century in Asia and Japan. Gamboge is composed of a yellow resinous component (70-80%; morelloflavone) and a clear water-soluble Gum (20%).
Gamboge has not yet been detected as a single colorant but has been found in mixtures with other colorants. (check)

Analysis
Gamboge does not fluoresce under UVA radiation and does not produce a distinct pattern using Excitation Emission Matrix (EEM) spectroscopy. Of the possible yellow colorants analyzed, it is the only bright yellow colorant that does not fluoresce but also absorbs the UVA induced fluorescence emitted by the paper. This negative indication was sometimes used to assign the presence of gamboge.
