目的:建立美味猕猴桃茎的HPLC指纹图谱。方法:采用HPLC法,色谱柱Thermo Hypersil BDS C18柱(250 mm×4.6 mm,5μm),流动相以乙腈-0.1%磷酸溶液梯度洗脱,柱温20℃,检测波长296 nm,流速1.0 mL/min,进样量20μL。结果:建立了美味猕猴桃茎药材的指纹图谱,并检测了不同产地16批美味猕猴桃茎药材,标定了28个共有峰,相似度较高,各色谱峰分离较好,达到中药指纹图谱研究的技术要求。结论:该方法准确可靠,为更好地控制药材内在质量提供了科学依据。
Objective: To establish the fingerprint spectrum of the stems of Actinidia deliciosa by HPLC.Methods: HPLC fingerprint analysis of the stems of Actinidia deliciosa was developed and the thermo Hypersil BDS C18 column(250 mm×4.6 mm,5 μm)was used.The mobile phase consisted of Acetonitril-0.1% phosphoric acid with gradient elution.The column temperature was 20℃,the detective wavelength was 296 nm,the flow rate was 1.0 mL/min,and the sample injection was 20 μL.Results: Fingerprint spectrum of the stems of Actinidia deliciosa was established,and 16 samples of different origin Actinidia deliciosa were detected.Twenty-eight peaks in chromatogram were common.There was a high similarity and each chromatographic peak was obtained with good separation correlation according to the technical requirements of fingerprint of Chinese traditional medicine.Conclusion: This method is accurate,reliable and provides a scientific basis for controlling the quality of the stems of Actinidia deliciosa.
