Abstract:
AIM To compare the contents of benzoyl mesaconitine,benzoyl hypaconitine,benzoyl aconitine,aconitine,hypaconitine and mesaconitine in Zingiberis Rhizoma Recens boiled juice-processed,Zingiberis Rhizoma boiled juice-processed,Zingiberis Rhizoma Recens juicing-processed,Zingiberis Rhizoma Recens slice malaxation steaming,and Zingiberis Rhizoma slice malaxation steaming Aconiti lateralis Radix Praeparata.METHODS Acid-base titration method was adopted in the content determination of total alkaloids.HPLC was applied to determining the contents of six alkaloids,the analysis was performed on a 35 ℃ thermostatic Waters Symmetry(C)C1scolumn (4.6 mm × 250 mm,5 μm),with the mobile phase comprising of acetonitrile-0.04 mol/L ammonium acetate flowing at 1.0 mL/min in a gradient elution manner,and the detection wavelength was set at 235 nm.RESULTS The contents of total alkaloids and diester-type alkaloids (mesaconitine,aconitine and hypaconitine)in various processed products,especially for Zingiberis Rhizoma Recens slice,Zingiberis Rhizoma slice malaxation steaming products,were obviously lower than those in the raw product.The contents of benzoyl hypaconitine and benzoyl aconitine in Zingiberis Rhizoma slice malaxation steaming product were the lowest,while that of benzoyl mesaconitine in the raw product was the lowest.CONCLUSION Compared with other Zingiber-processing methods,both Zingiberis Rhizoma Recens slice and Zingiberis Rhizoma slice malaxation steaming can reduce the toxicity of Aconiti lateralis Radix Praeparata more effectively.
