Abstract:
To analyse the quality of three processed products of Rhizome of Curcuma wenyujin by establishing an ultra performance liquid chromatography (UPLC) method for simultaneously determining five sesquiterpene components in three processed products of rhizome of C. wenyujin and establishing UPLC fingerprints. Component determination was achieved on Waters ACQUITY UPLC BEH C₁₈ column（2.1 mm×50 mm, 1.7 μm), with acetonitrile-water as mobile phase for gradient elution. The flow rate was 0.3 mL·min⁻¹; column temperature was 30 °C; the detection wavelength was set at 214 nm and injection volume was 1 μL. The similarity was analyzed with "Similarity Evaluation System for Chromatographic Fingerprint of Chinese Materia Medica (2012.130723)", and hydrophobic cluster analysis (HCA), principal components analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA) were conducted by using simca-p14.1 software to investigate the differences in components among these three kinds of processed products. The curzerene, curdione, curcumol, germacrone, furanodiene and β-elemene showed good linearity relationship with chromatographic peak area within the ranges of 10.8-320（=0.999 9）, 10.36-259（=0.998 1）, 10.54-263.5（=0.999 3）, 30.2-755（=0.999 6）and 34.38-862（=0.999 9）mg·L⁻¹, respectively; their average recoveries were 98.75%, 98.69%, 98.63%, 99.76% and 99.57% respectively, with RSD of 2.67%, 1.47%, 1.29%, 2.54% and 0.87% respectively. The similarity of 30 batches of samples was larger than 0.9, indicating good consistency of the samples. The samples can be clearly classified into three categories for HCA, PCA and OPLS-DA pattern recognition, the differential chromatographic peak among three processed products was found respectively. The results showed that the pharmacology basis had changed obviously after processing of Rhizome of C. wenyujin, so it can provide the scientific basis for rational clinical application and establishing quality standards of three processed products of Rhizome of curcuma wenyujin.
