Baking method of Platycladi Cacumen Carbonisatum based on similarity of UPLC fingerprints / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To establish a baking method of Platycladi Cacumen Carbonisatum for providing a new idea to Carbonic Herbs' research.</p><p><b>METHOD</b>Samples were prepared in an oven for different time at different temperatures separately. Then the fingerprints of the samples were determined by UPLC. According to the standard fingerprint, the similarities of the samples' fingerprints were compared.</p><p><b>RESULT</b>The similarities of 3 samples, which were baked at 230 degrees C for 20 min, 30 min and at 240 degrees C for 20 min, were above 0.96.</p><p><b>CONCLUSION</b>According to the similarities of the fingerprints and in view of the appearances, Platycladi Cacumen Carbonizing should be baked at 230 degrees C for 20 min.</p>
