Abstract: Anew method for analysing the ingredients of rhynchophylline and isrhynchophylline in Uncaria Rhynchophylla Jacks using hyphenaed high efficiency thin layer chromatographic(TLC) and the surface-enhanced raman spectroscopic(SERS) technics is reported. The results show that the characteristic spectral bands of rhynchophylline can be obtained from the TLCspot with minimum amount of rhynchophylline sample of about 25 mm diameter. The difference between the SERSand solid spectra are found. Spectral band at 1397 cm-1 was obtained wits great enhanced want. Molecule was absorbed in surface silver sol by pair of electrons in —OCH3. Isrhynchophylline sample spectrum band at 1615 cm-1 obtained the greatest enhance. Isrhynchophylline molecule was absorbed in surface silver sol by pair of electron at Natom in ring indole. An absorption model of rhynchophylline and isrhynchophylline and silver sol is proposed. That effective combination of TLCand SERScan be used to analyse the chemical ingredients with high sensitivity.
