Correlation between HPLC Fingerprints and Activity of Rhizoma coptidis in Ameliorating Insulin Resistance in Vitro

The fingerprints of Rhizoma coptidis from various producing areas were established by High performance liquid chromatography (HPLC), and the activity of R. coptidis in ameliorating insulin resistance in vitro was studied by colorimetry. The HPLC fingerprints were evaluated using the similarity analysis (SA) and the principal component analysis (PCA). The correlation between HPLC fingerprints and activity of of R. coptidis in ameliorating insulin resistance in vitro was investigated using the grey correlation analysis (GCA) and the multiple correlation analysis (MCA). Peak 10, peak 6, peak 3, peak 7 and palmatine in the HPLC fingerprints were found to be the main active constituents to ameliorate insulin resistance. Some ecological factors of the producing areas, such as the climate, the latitude and longitude, artificial factors might also influence the function of R. coptidis. This work primarily revealed the correlation between HPLC and amelioration of insulin resistance by R. coptidis, which may help to screen the active ingredients of R. coptidis to ameliorate insulin resistance.
