Chemical stability of Salvia miltirrhiza hairy root / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study on the chemical stability of Salvia miltirrhiza hairy root.</p><p><b>METHOD</b>The rolA gene was detected by PCR in DNA and the chemical contituent variances were detected by HPLC.</p><p><b>RESULT</b>The rolA gene was found in all the 10 batches of the culfured hairy root. The similarities of the chromatographic fingerprints of the 10 batches are higher than 0. 95.</p><p><b>CONCLUSION</b>There are no significant differences of the chemical constituents in 10 hairy root samples.</p>
