Objective:
To study on the chemical stability of Salvia miltirrhiza hairy root.
Method:
The rolA gene was detected by PCR in DNA and the chemical contituent variances were detected by HPLC.
Result:
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.
Conclusion:
There are no significant differences of the chemical constituents in 10 hairy root samples.
