To determine the suitable conditions for extracting alkaloidals from Aconitum carmichaili. Using methods in Chinese Pharmacopeia for determining yields of extraction, which include spectrometry and single-factor tests, we investigated vavious factors that would affect the extraction of alkaloids from Aconiti. The suitable extractant was 85% ethanol, starting material was medium-size powder of aconiti, 10 times of the volume of the solvent was used in extraction for twice 1.75 h each time. The extraction yield was 1.21%, with a content of 0.33% alkaloids. Extraction conditions determined with single factor test was consistent and feasible.
