| Abstract: | Objective To establish a method for extracting and separating mesaconitine,aconitine and hypaconitine.Methods Aconitum kusnezoffii reichb was extracted with0.2mol/L HCl and adjusted to pH10.The precipitate was chromatographed over neutral alumina.Each alkaloid's structure was identified with IR and EI-MS.Results The recovery received from this method was similar with that of ammoniacal benzene method.Conclusion This method was at low cost,harmless and suitable for preparing mesaconitine,aconitine and hypaconitine. |
