目的
2
构建地乌药材基原物种系统鉴定体系,并对全国16个产地的地乌药材进行综合品质评价,为地乌药材产地选择及临床用药安全奠定基础。
方法
2
使用传统鉴别方法结合DNA条形码核糖体DNA第二内部转录间隔区(ITS2)序列分子鉴定技术快速鉴别地乌药材真伪,并基于HPLC-UV对地乌药材中5个有效成分进行含量测定,采用Welch Ultimate XB-C
18
色谱柱(4.6 mm×250 mm,5 μm),流动相乙腈-0.01%三氟乙酸溶液(30∶70),检测波长210 nm,柱温30 ℃,流速1.0 mL·min
-1
。
结果
2
传统鉴别及DNA条形码快速鉴别技术均能准确鉴别地乌药材真伪。BLAST比对分析发现,16个产地地乌药材均与林荫银莲花
Anemone flaccida
具有最大相似度;基于多指标成分含量测定表明湖北恩施板桥镇的地乌药材中5个三萜皂苷类成分含量之和最高(10.59%),其次为贵州毕节赫章(6.28%)和湖北长阳都镇湾(5.64%)。
结论
2
DNA条形码技术可作为地乌药材传统鉴定技术的有效补充,该鉴别体系可保障地乌药材基原准确及临床用药安全。HPLC多指标成分综合评价及聚类分析结果表明在本研究所涉及的产地中,湖北恩施、长阳、五峰,贵州毕节和重庆金佛山的地乌药材质量较优,可作为地乌药材的重要产地。
Objective
2
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.
