Systematic Identification and Quality Evaluation of Anemonis Flaccidae Rhizoma from 16 Different Places of Origin
To construct a systematic identification system of Anemonis Flaccidae Rhizoma
and to evaluate the comprehensive quality of Anemonis Flaccidae Rhizoma from 16 regions in China
so as to lay a foundation for its origin selection and clinical medication safety.
Method
2
The authenticity of Anemonis Flaccidae Rhizoma was quickly identified by traditional identification method and DNA barcode molecular identification technology
and HPLC-UV was used to determine the contents of 5 active ingredients in Anemonis Flaccidae Rhizoma. All high pressure chromatographic separations were performed with a Welch Ultimate XB-C
18
column (4.6 mm×250 mm
5 μm)
the mobile phase consisted of acetonitrile-0.01% trifluoroacetic acid aqueous solution (30∶70) at a flow rate of 1.0 mL·min
-1
. The detection wavelength was set at 210 nm and the column temperature was maintained at 30 ℃.
Result
2
The authenticity of Anemonis Flaccidae Rhizoma could be precisely and rapidly identified by ribosomal DNA internal transcribed spacer 2 (ITS2) sequence and traditional identification methods. BLAST comparative analysis found that medicinal materials from 16 areas were all
Anemone flaccida
. Based on the contents of multi-index components
it was shown that the total content of 5 triterpenoid saponins in Anemonis Flaccidae Rhizoma from Banqiao
Enshi
Hubei was the highest (10.59%)
followed by Hezhang
Bijie
Guizhou (6.28%) and Duzhenwan
Changyang
Hubei (5.64%).
Conclusion
2
DNA barcoding can be used as an effective supplement to the traditional identification technology
it can ensure the authenticity of Anemonis Flaccidae Rhizoma and the safety of clinical use. The comprehensive evaluation of multi-index components of HPLC and cluster analysis show that the quality of medicinal materials in Enshi
Changyang
Wufeng of Hubei
Bijie of Guizhou and Jinfoshan of Chongqing is superior
which can be considered as important origin of Anemonis Flaccidae Rhizoma.
