TITLE:
摘要: 目的:为骨碎补中柚皮苷的提取及测定开辟新的途径。方法:采用ASE350型快速溶剂萃取系统提取骨碎补中的柚皮苷;以高效液相色谱法测定骨碎补中柚皮苷的含量。色谱柱为Kinetex XB-C18,流动相为甲醇-5%乙酸(25 ∶ 75,V/V),流速为0.8 ml/min,检测波长为283 nm,柱温为40 ℃,进样量为10 μl。结果:柚皮苷的进样量线性范围为0.073 0~0.730 0 μg(r=0.999 9));定量限为0.73 μg,检测限为0.022 μg;精密度、稳定性、重复性试验的RSD<2%;加样回收率为98.92%~100.85%(RSD=0.72%,n=6)。结论:该方法简便、准确、专属性强,可用于测定骨碎补中柚皮苷的含量。
ABSTRACT: OBJECTIVE: To develop a new way for the extration and determination of naringin in Davallia mariesii. METHODS: Naringin in D. mariesii was extracted by ASE350 accelerated solvent extraction system; HPLC was performed for the content determination of naringin in D. mariesii, the column was Kinetex XB-C18 with mobile phase of methanol-5% acetic acid(25 ∶ 75,V/V) at a flow rate of 0.8 ml/min, detection wavelength was 283 nm, column temperature was 40 ℃, and injection volume was 10 μl. RESULTS: The linear range of naringin was 0.073 0-0.730 0 μg(r=0.999 9); the limit of quantitation was 0.73 μg, the limit of detection was 0.022 μg; RSDs of precision, stability and reproducibility tests were lower than 2%; recovery was 98.92%-100.85% (RSD=0.72%,n=6). CONCLUSIONS: The method is simple, accurate and specific, and can be used for the content determination of naringin in D. Mariesii.
