【Abstract】 We have obtained a new method to analyze the ingredients of qurecetin.A combination of the highly efficient thin layer chromatographic(TLC)dissociation technology and the surface enhanced Raman spectroscopy (SERS)technique is used.The results of SERS show that vibrational spectral features of qurecetin can be measured at the original position of TLC minimum amount of qurecetin sample required is about 3μg.We establish that effective combination of TLC and SERS can be used to analyze the chemical ingredients with high sensitivity.This mathod can be applied to study Chinese medical herbs.更多还原
