HPLC-FP法同時測定新品富硒竹筍中10種核苷類成分的含量

Simultaneous Determination of Ten Nucleosides in New Selenium-enriched Bamboo Shoots by HPLC-FP

  • 摘要: 目的:建立同時測定不同品種富硒竹筍中胞嘧啶、尿嘧啶、胞苷、次黃嘌呤、尿苷、胸腺嘧啶、腺嘌呤、鳥苷、胸苷、腺苷10種核苷類化合物含量的方法。方法:運用HPLC法同時測定21種不同品種竹筍的核苷類化合物含量,色譜柱為Inertsil ODS-3 C18,流動相為乙腈-水(梯度洗脫),檢測波長為260 nm,流速為0.8 mL·min?1,柱溫為30 ℃,進樣量為20 μL。繪制21種富硒竹筍的指紋圖譜進行相似度評價,確定共有峰,并用主成分分析、相關性分析和聚類分析對21種不同富硒竹筍的核苷類化合物含量測定結果進行分析。結果:10種核苷類成分在30 min內達到分離,線性關系良好(R2≥0.9990),精密度、穩定性、重復性、準確度試驗RSD均小于2%。不同品種富硒竹筍中10種核苷類成分含量與結構比差異明顯,并且核苷類化合物成分指標互相間存在著不同程度的相關性。通過主成分分析,提取了4個主成分,并確定了胸苷、胸腺嘧啶、腺苷、鳥苷為4項核心指標,可用于評價不同品種富硒竹筍的品質;通過相關性分析,得出尿嘧啶與胞苷、鳥苷與胸苷、胸苷與腺苷等指標間相關性較高,指標之間的含量會互相影響;通過聚類分析,得出新品富硒竹筍主要集中為一類,市場上常見的富硒竹筍主要分為兩類。結論:該實驗方法操作快速、簡便,重現性好,可用于21種富硒竹筍中10種核苷類化合物的含量測定。同時,測定結果為竹筍的后期高效開發和利用提供理論依據。

     

    Abstract: Objective: To establish a method for simultaneous determination of cytosine, uracil, cytidine, hypoxanthine, uridine, thymidine, adenine, guanosine, thymidine and adenosine in different selenium-rich bamboo shoots. Methods: The determination was performed on Inertsil ODS-3 C18 column with mobile phase consisting of acetonitrile-water (gradient elution). The detection wavelength was set at 260 nm and the flow rate was 0.8 mL·min?1. The column temperature was 30 ℃, and the sample size was 20 μL. Fingerprints of 21 selenium-rich bamboo shoots were drawn for similarity evaluation of common peaks. The nucleosides of 21 selenium-rich bamboo shoots were analysised by principal component analysis, correlation analysis and cluster analysis. Results: 10 nucleosides were separated within 30 min, and the linear relationship was good (R2≥0.9990). RSDS of precision, stability, repeatability and accuracy tests were all less than 2%. Significant differences in the contents and structure ratio of 10 nucleosides were found in different selenium-rich bamboo shoots, and there were different degrees of correlation between nucleoside components. Four principal components were selected by principal component analysis. Thymidine, thymine, adenosine and guanosine were identified as four core indexes, which could be used to evaluate the quality of different selenium-rich bamboo shoots. The correlation between uracil and cytidine, guanosine and thymidine, thymidine and adenosine was high, and the contents of these indexes would influence each other. After cluster analysis, it was concluded that the new selenium-rich bamboo shoots were mainly concentrated in one category, and the common selenium-rich bamboo shoots in the market are mainly divided into two categories. Conclusion: The method was rapid, simple and reproducible, and could be used for the determination of 10 nucleosides in 21 selenium-rich bamboo shoots. At the same time, the results would provide a theoretical basis for the efficient development and utilization of bamboo shoots in the later period.
