Establishment of processing method of Radix Aconiti carmichaelii lateralis in Sa Pa

ABSTRACT

Study on processing methods of Radix Aconiti carmichaelii lateralis collected at Sa Pa from August 2003 to September 2003. Results: processing method of Radix Aconiti carmichaelii lateralis included these steps: Radix Aconiti were soaked in the MgCl2 and NaCl solutions, boiled, sliced, and dried. Studied samples all contained alcaloid, alcaloid of processed Radix Aconiti had maximum absorbing of ultraviolet spectrum in wavelength of 231nm and 274nm. This analysis could be used for quantitative study. The contents of total alcaloids of processed Radix Aconiti carmichaelii lateralis and diester alcaloids were 0.14-0.17% and 0.017-0.025%, respectively. The product increased amplitude of frog heart beat clearly at concentrations of 20 and 40g/l, but didn’t cause arrhythmia
