Abstract:
Objective To establish the basis of molecular systematics of Angelica from different areas of Gansu province so as to offer molecular basis of identification Gansu-produced Angelica with geoherbalism. Methods The ITS gene of Angelica was obtained by PCR and sequenced to be analyzed by DNAStar software to calculate the genetic distance among different specimens. Results The ITS sequence of Angelica between Min County and Zhang County of Gansu Province shows trivial differences with the range of 0.000 0～0.008 3. All 5 Min County-produced Angelica specimens have same bases at 586 site with "C" and 589 site with "T" with Zhang County-produced Angelica DG9 specimen, whereas the 586 site and 589 site bases of the other 3 Zhang County-produced Angelica specimens are "T" and "G" respectively. Conclusion The ITS sequence characteristics can be recognized as effective molecular marker of Angelica, and both 586 site base and 589 site base of the ITS sequence of Angelica can be recognized as identification bases of Min County-produced Angelica.
