摘要
Curcumin is isolated from turmeric. The effect of solvent composition on the total extraction yield of turmeric has been investigated using the dipping method. HPLC-UV diode-array (DAD), electrospray mass spectrometry (ESI) and TLC have been used simultaneously to analyze curcumin in a fresh turmeric extract. From the results, it is evident that the percentage of curcumin extracted from turmeric by pure methanol was higher than any aqueous methanol composition; although the total extraction yield was the highest in 100 To water.
