|
The current definition of Arismatis Rhizoma is the tuberous root of Alisma orientale Juzepzuk in the Korean Pharmacopoeia, but there is still no marker compound. So it has difficulties in quality control. Therefore, in this study, we have established a method to analyze alisol B and alisol B acetate using HPLC as a marker compounds of Arismatis Rhizoma. As the result of the analysis, alisol B content was ranged from 0.02% to 0.50% and alisol B acetate content was ranged from 0.12% to 0.25% in 40 samples. The stability of alisol B and alisol B acetate was investigated during 24 months. As a result, alisol B acetate was significantly decreased. The marker compound of Arismatis Rhizoma is alisol B acetate and the content of 0.05% or more is suitable by applying the stability results.
