Studies on content determination and fingerprint of active constituents in different parts of cortex moutan / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To determine the chemical constituents in different parts of Cortex Moutan, which can provides evidences to the processing techniques of Cortex Moutan.</p><p><b>METHOD</b>The contents of paeonol, peoniflorin and fingerprints in different parts of Cortex Moutan were determined by HPLC.</p><p><b>RESULT</b>Compareed with phloem, paeonol in cork is twice as many, but paeonol in duramen is half as many peoniflorin in cork is half and four times as many, peoniflorin in duramen is twice as many, the contents of active ingredients in duramen are high in fingerprint.</p><p><b>CONCLUSION</b>If we only abandon the core, then we may get simple processings with the active ingredient contents increasing.</p>
