Assay of evodin, evodiamine and rutaecarpine in Fructus Evodiae by QAMS / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To develop a Quantitative Assay of Multi-components by Single - marker (QAMS) for simultaneous determination of three components in Fructus Evodiae, and examine the feasibility of using the relative correction factors between the different types of compounds.</p><p><b>METHOD</b>Rutaecarpine was selected as the internal reference substance; the relative correction factors of evodin and evodiamine were calculated. The contents of three components in 11 batches of samples were determined by both external standard method and QAMS. The validity of the QAMS method was evaluated by comparison of their quantitative results.</p><p><b>RESULT</b>No obvious differences (RSD < 5%) were found in the quantitative results of evodin and evodiamine in 11 batches of Fructus Evodiae determined by the two methods.</p><p><b>CONCLUSION</b>It is feasible and suitable to determine evodin and evodiamine in Fructus Evodiae by QAMS, and this method can be used for a certain different types of compounds.</p>
