Study on HPLC characteristic fingerprint of active components of dachuanxiong fang in plasma and cerebrospinal fluid / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To establish an accurate and simple qualitative analytical method in vivo in the study on HPLC characteristic fingerprint of active components of dachuanxiong fang in plasma and cerebrospinal fluid, in order to lay a foundation for studies on components found in plasma and cerebrospinal fluid and provide basis for compatible regularity of initiators.</p><p><b>METHOD</b>HPLC characteristic fingerprint of active components of dachuanxiong fang in plasma and cerebrospinal fluid was established.</p><p><b>RESULT</b>The similarity of fingerprints of all of six batches of samples was above 0.85, RSD of their relative retention times in common peaks was less than 2. 0%.</p><p><b>CONCLUSION</b>The fingerprints of active components of dachuanxiong fang in plasma and cerebrospinal fluid were stable and accurate that they can be used in qualitative analysis on in vivo components.</p>
