摘要: |
目的 HPLC测定黔产钩藤不同部位中钩藤碱和异钩藤碱的含量,并比较其差异。方法 以钩藤碱、异钩藤碱为对照品,采用CAPCELL PAK C18色谱柱(4.6 mm×250 mm,5μm),以乙腈-0.1%三乙胺水溶液(1%磷酸调pH=9)为流动相,流速1 mL·min-1,检测波长245 nm,柱温30℃,进样量10µL。结果 钩藤碱与异钩藤碱分离良好,线性、重复性以及回收率均符合要求,钩藤不同部位中的含量存在差异,由高到低依次为皮 > 茎 > 带钩茎枝 > 叶,而茎薄壁组织与木质部未检测到钩藤碱与异钩藤碱。结论 该含量测定结果为钩藤资源的充分利用提供了科学依据。 |

Abstract: |
OBJECTIVE To determine the contents of rhynchophylline and isorhynchophylline from different parts of Uncaria rhynchophylla by HPLC and compare the difference of contents. METHODS Rhynchophylline and isorhynchophylline were used as reference substances. CAPCELL PAK C18(4.6 mm×250 mm, 5 µm) was used for chromatographic separation. The mobile phase was acetonitrile-0.1% triethylamine solution(adjust pH to 9 with 1% phosphoric acid). The flow rate was 1 mL·min-1, the detection wavelength was 245 nm, the column temperature was 30℃ and the injection volume was 10 µL. RESULTS Rhynchophylline and isorhynchophylline separated well. The linearity, repeatability and recovery also met with the requirements. There were difference from different parts in U. rhynchophylla. This study showed that the contents of rhynchopylline and isorhynchophylline were in an order as:bark > stem > hooked stem > leave. Rhynchophylline and isorhynchophylline could not be detected in stem parenchyma and xylem. CONCLUSION The results of this study provide a basis for the full utilization of U. rhynchophylla. |
