Objective: To investigate quality of Curcumae Longae Rhizoma from different areas by analyzing correlation relationship of demethoxycurcumin
bisdemethoxycurcumin
curcumin and volatile oil in this herb. Method: Samples of Curcumae Longae Rhizomafrom different areas were collected
contents of curcuminoids were quantified by HPLC-UV whereas volatile oil was determinate by this method in the 2010 edition of Chinese Pharmacopoeia.Determination were analyzed by cluster and person correlation analysis with SPSS 20.0 software. Result: Effective ingredientsin Curcumae Longae Rhizomafrom different areas had a remarkable difference
when a maximum value of curcuminoids was about 4.9%
a minimum value was about 0.2%.Content of volatile oil in Curcumae Longae Rhizoma between the maximum and minimum values reached 4.2 times.Significant positive correlation had been showed between demethoxycurcumin
bisdemethoxycurcumin
curcumin and volatile oil. Conclusion: Altitude difference has effecton contents of curcuminoids in Curcumae Longae Rhizoma.Farming location of Curcumae Longae Rhizoma need to carry on reasonable planning to improve its quality and to promote sustainable development of industry.
