Abstract:
AIM: To establish a quality control method of analysing Lajiao Fengshi Plaster qualitatively and quantitatively. METHODS: Capsaicin was identificated by TLC and menthol,borneol were determinated by GC Lajiao Fengshi Plaster,silica gel as plate,ligarine(60～90?C)-acetoacetate(3(∶)2) as mobile phase,0.5% solution of dichloroquinonechlorimide R in methanol R.as chromogenic agent to identificate capsaicin.The internal standard of GC,naphthalene was employed.10% PEG-20M as the stationary phase,column temperature at 150(?C,) and FID as the detector to determine methol and borneol. RESULTS: There were the same spot corresponding in colour and position sample and reference capsaicin,but negative control had not such colour spot in the same plate of TLC.Menthol,borneol and naphthalene had been separated well under the chromatographic condition.The average recovery of menthol,borneol were 97.44%(RSD=0.93%),98.09%(RSD=1.26%),respectively. CONCLUSION: The method is sensitive,accurate and reproducible and can be used to control the quality of Lajiao Fengshi Plaster.
