The contents of alkaloids in raw Cho O(Aconiti Ciliare Tuber) and its processed products were determined by high performance liquid chromatography. Processing methods 1 and 2 lowered the contents of alkaloids more than the method 3. Cho O processed with method 1 or 2 showed even lower alkaloid contents than commercially available Processed Aconiti Tuber Powder(PATP). The contents of aconitine and hypaconitine in MeOH extracts of Cho O treated with method 3(10 min irradiation) and mesaconitine of Cho O treated with method 3(5 min) were comparable to those of PATP.

Crude Aconiti Tubers were irradiated with microwave for 5 or 10 min with or without $NaHCO_3$. Ten min-irradiation reduced the contents of aconitine and mesaconitine to the level of those of commercially available processed Aconiti tuber power which is prepared with the high pressure-high temperature technique. The contents of benzoylaconine of the 10 min-irradiated Aconiti tubers were also comparable to those of commerciallized processed Aconiti tuber powder. However, irradiation with 1% $NaHCO_3$ soln. resulted in the drastic reduction of all the three above alkaloids.

Mesaconitine and hypaconitine were isolated from Cho O and identified by the spectroscopic methods. The contents of alkaloid (mesaconitine. aconitine and hypaconitine) in the Cho O and its processed products were determined by high performance liquid chromatography. Processed 1 and 2 methods reduced the contents of alkaloid than those of processed 3 and commercially processed Aconiti Tuber powder. (omitted)
