Objective: To compare the diversity of curcumin content in Curcuma longa before and after processed. Method: The column of HPLC was SHIMADZU VP-ODS C18 (4.6 mm×250 mm
5 μm)
the mobile phase was acetonitrile-0.1% acetic acid (48∶52)
V=1.0 mL·min-1
λ= 430 nm
t=30 ℃. Volatile oil was extracted with steam distillation. Result: The content of curcumin in different processed products of C. longa was as folllows: raw materials(10.77 mg·g-1)>slightly fried sample(10.04 mg·g-1)>primitive(10.02 mg·g-1)>liquor-fried sample (9.44 mg·g-1)>vinegar-fried sample (9.28 mg·g-1). The content of volatile oil was as follows: raw materials(8.05%)>primitive(8.00%)>liquor-fried sample (7.99%)>slightly fried sample(7.81%)> vinegar-fried sample(7.60%). Conclusion: Different processed methods may have some affection to the quality of C. longa.
