OSTI ID:4827601

ABS>A weighed sample is evaporated to dryness with caustic soda solution on a water bath. The residue is dissolved by addlng a solution of curcumin in acetic acid. After adding a mixture of H/sub 2/SO/sub 4/ and acetic acid, the solution is allowed to stand at room temperature for 15 minutes. The solution is then diluted to 100 ml with ethanol, and a portion is filtered and measured absorptiometrically on the residue as the curcumin complex. (P.C.H.)
