+The vitality of the rhizomes is destroyed by scalding previous to drying, thus converting the grains into lumps, to which the mixture of oil and curcumin liberated from the oil cells imparts a deep yellow color.  As found on the market, the product is hard, tough, and sinks in water.  The fractured surface is smooth, waxy, of an orange-yellow color.  As appears in cross section, the rind is thicker than in ginger, constituting almost one-quarter of the thickness of the rhizome.  It cannot be removed by scraping.

 Test for adulteration: Compare result with reference images. The fingerprint of the test solution is similar to that of the corresponding botanical reference sample. Additional weak zones may be present. The chromatogram of the test solution shows no zone at Rf ~ 0.51 corresponding in color and position to that of the nimesulide reference standard.
