Study on the Content of Alkaloids and Polysaccharide in Different Varieties of Aconitum carmichaeli / 中国药房

ABSTRACT

OBJECTIVE: To research the content of alkaloids and polysaccharides in different varieties of Aconitum carmichaeli. METHODS: The contents of total alkaloids, diester diterpenoid alkaloids and polysaccharides were measured by acid dye colorimetry, HPLC and sulphuric acid-anthrone colorimetric method respectively. RESULTS: In different varieties, the differences of total alkaloids and diester diterpenoid alkaloids were significant. However, the difference of polysaccharides wasn’t significant. The content of total alkaloids and diester diterpenoid alkaloids in processed A. carmichaeli reduced significantly while the content of polysaccharides increased slightly. CONCLUSION: The results of study could provide a scientific basis for rational breeding of A. carmichaeli.
