摘要
目的研究3个不同品种升麻的指纹图谱。方法采用YMC-Pack-ODS-C18(250 mm×4.6 mm,5μm)色谱柱;流动相为乙腈-0.1%磷酸水溶液,梯度洗脱;流速:1.0mL·min~(-1);柱温:30℃;检测波长:320nm;进样量:10μL。结果建立了3个不同品种升麻的指纹图谱,分别鉴别出兴安升麻特征峰17个,大三叶升麻特征峰19个,升麻特征峰23个。结论该方法重复性好,简单可靠,为升麻药材定性鉴别提供理论基础。
OBJECTIVE To study the fingerprints of three different species of Cimicifuga Rhizoma. METHODS YMC-Pack-ODS-C18 column(250 mm×4.6 mm, 5 μm) was taken for study, the mobile phase was acetonitrile-0.1% phosphoric acid solution with gradient elution at the flow rate of was 1.0 mL·min~(-1), the column temperature was 30 ℃, the detection wavelength was 320 nm and the injection volume was 10 μL. RESULTS The fingerprints of three different species of Cinicifuga Rhizoma were established. Seventeen characteristic peaks of Cimicifuga dahurica(Turcz.) Maxim, 19 characteristic peaks of Cimicifuga heracleifolia Kom. and 23 characteristic peaks of Cimicifuga foetida L. were pointed out, respectively.CONCLUSION This method is reproducible, simple and reliable, can provide a theoretical basis for the qualitative identification of Cinicifuga Rhizoma.
