摘 要:目的:通过连翘不同部位的连翘苷和连翘酯苷A的含量比较,为连翘资源的综合开发利用提供科学依据。方法:采用HPLC测定连翘果实、叶、果梗、枝梗中连翘苷和连翘酯苷A的含量,以Luna5uC18(2)100A(250 mm×4.6 mm,5 μm)为色谱柱,连翘苷测定流动相为乙腈-水(25∶75),检测波长为277 nm,柱温为室温,流速为1.0 mL·min-1;连翘酯苷A测定流动相为乙腈-0.4%冰醋酸溶液(15∶85),检测波长为330 nm,柱温为室温,流速为1.0 mL·min-1。结果:连翘苷在3.33~13.32 μg线性关系良好(r=0.999 7),平均回收率为99.30%,RSD=1.4%;连翘酯苷A在4.17~6.69 μg具有良好的线性关系(r=0.999 7),平均回收率为98.26%,RSD=1.8%。结论:连翘苷含量在不同部位中叶子最高,其次为果实、枝梗、果梗;连翘酯苷A含量在不同部位中同样叶子最高,其次为果实、果梗、枝梗。Objective : To provide theoretical basis for comprehensive development and utilization of Forsythia suspensa resources by evaluating the contents of forsythin and forsythiaside A in different parts of Forsythia suspense. Methods: HPLC method was used for analyzing the contents of forsythin and forsythiaside A for 4 samples of different parts of Forsythia suspense. Luna5uC17(2) 100A (250 mm ×4. 6 mm,5 μm) Column was carried out,the mobile phrase of forsythin determination was acetonitrile-water ( 25 : 75 ), the detection wavelength was 277 nm. The mobile phase of forsythiaside A determination was acetonitrile -0. 4% acetic acid (15:85) and the detection wavelength was 330 nm. The column temperature was room temperature. And the flow rate was 1.0 mL. min-I Results: There was a good linear relationship (r = 0. 999 7 ) for forsythin at 3.33 - 13.32 μg, the average recovery rate was 99. 30% ,and RSD was 1.4%. The good linear relationship (r =0. 999 7) for forsythiaside A was at 4. 17 -6. 69 μg,the average recovery rate was 98.26% ,and RSD was 1.8%. Conclusion: The highest content of forsythin was in leaves, followed by fruit and branches, the highest content of forsythiaside A was in leaves, and followed by fruits, stems and branches.
