Gamboge 藤黄 (tōō): A yellow-orange gum resin produced by several species of the Garcinia tree, such as Garcinia morella found in South Asia and Garcinia hanburyi found in Southeast Asia. Gamboge is composed of a yellow resinous component (70-80%; morelloflavone) and a clear water-soluble gum (~20%). Gamboge is obtained by scoring the trunks of mature trees (older than ten years) and then collecting the poisonous milky yellow resin in hollow bamboo canes. Once the resin has congealed, the bamboo is roasted over fire to evaporate any remaining moisture. Then, the bamboo is broken away to reveal rods of raw gamboge. These rods of gamboge are pulverized, transforming its color from a dull to bright yellow powder.

Gamboge produces a transparent yellow which was frequently hand-painted on prints dating from the 1690s to the 1740s. After the introduction of full color printing, its use seems to decline perhaps because other yellows were easier to obtain and/or print as well as mix with other colorants.

Analysis

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