Original Recipe Text
The major marker curcumin was identified at 22.2 min, which is close to the expected 23.5 min of the standard (p. 12).
Evidence
"Only one sample, AS16, was found to be dyed with turmeric. The major marker of turmeric, curcumin, was identified with good correspondence of the spectrum"
Remarks
In turmeric-dyed model samples, three curcuminoids are typically detected: curcumin, demethoxycurcumin, and bisdemethoxycurcumin (p. 5). For historical sample AS16, only curcumin was definitively matched (p. 12).
