TITLE:
摘要: 目的:建立同时测定五酯片中五味子酯戊、戈米辛J、当归酰戈米辛H、五味子酯甲、五味子酯乙、五味子酚、安五脂素、五味子甲素、五味子乙素、五味子丙素10种木脂素类成分的含量。方法:采用反相高效液相色谱法。色谱柱为Symmetry C18,流动相为乙腈-0.1%磷酸溶液(梯度洗脱),流速为1.0 mL/min,检测波长为225 nm,柱温为30 ℃,进样量为10 μL。结果:五味子酯戊、戈米辛J、当归酰戈米辛H、五味子酯甲、五味子酯乙、五味子酚、安五脂素、五味子甲素、五味子乙素、五味子丙素检测进样量线性范围分别为2.25~67.5 ng(r=0.999 6)、2.1~63 ng(r=0.999 8)、28~840 ng(r=0.999 9)、124.6~3 738 ng(r=0.999 9)、22.7~681 ng(r=0.999 9)、32.7~981 ng(r=0.999 9)、47~1 410 ng(r=0.999 9)、208~6 240 ng(r=0.999 9)、5.36~160.8 ng(r=0.999 9)、4.48~134.4 ng(r=0.999 8);定量限分别为14.17、13.32、9.33、11.37、14.62、19.88、14.66、12.50、16.40、13.55 ng,检测限分别为4.62、4.60、3.08、3.76、4.81、6.74、4.93、4.16、5.86、5.03 ng;精密度、稳定性、重复性试验的RSD<3.0%;加样回收率分别为 96.36%~100.00%(RSD=1.83%,n=6)、95.00%~100.00%(RSD=2.07%,n=6)、95.00%~98.00%(RSD=1.22%,n=6)、95.37%~98.91%(RSD=1.29%,n=6)、95.62%~103.71%(RSD=2.85%,n=6)、97.33%~102.67%(RSD=2.00%,n=6)、95.00%~99.33%(RSD=1.75%,n=6)、97.24%~104.93%(RSD=2.63%,n=6)、95.00%~97.50%(RSD=1.42%,n=6)、96.00%~102.00%(RSD=2.45%,n=6)。结论:该方法结果准确、灵敏度高、重复性好,可用于五酯片中10种木脂素类成分含量的同时测定。
ABSTRACT: OBJECTIVE: To establish a method for content determination of schizantherin E, gomisin J, angeloylgomisin H, schisantherin A, schisantherin B, schisanhenol, anwuligan, schizandrin A, schizandrin B and schizandrin C in Wuzhi tablets. METHODS: RP-HPLC method was adopted. The determination was performed on Symmetry C18 column with acetonitrile-0.1% phosphoric acid solution (gradient elution) at the flow rate of 1.0 mL/min. The detection wavelength was set 225 nm, and the column temperature was 30 ℃. The sample size was 10 μL. RESULTS: The linear ranges of schizantherin E, gomisin J, angeloylgomisin H, schisantherin A, schisantherin B, schisanhenol, anwuligan, schizandrin A, schizandrin B and schizandrin C were 2.25-67.5 ng(r=0.999 6), 2.1-63 ng(r=0.999 8), 28-840 ng(r=0.999 9), 124.6-3 738 ng(r=0.999 9), 22.7-681 ng(r=0.999 9), 32.7-981 ng(r=0.999 9),47-1 410 ng(r=0.999 9), 208-6 240 ng(r=0.999 9), 5.36-160.8 ng(r=0.999 9), 4.48-134.4 ng(r=0.999 8). The limits of quantitation were 14.17,13.32,9.33,11.37,14.62,19.88,14.66,12.50,16.40,13.55 ng. The limits of detection were 4.62,4.60,3.08,3.76,4.81,6.74,4.93,4.16,5.86,5.03 ng. RSDs of precision, stability and reproducibility tests were less than 3.0%; the recoveries were 96.36%-100.00%(RSD=1.83%,n=6), 95.00%-100.00%(RSD=2.07%,n=6), 95.00%-98.00%(RSD=1.22%,n=6), 95.37%-98.91%(RSD=1.29%,n=6), 95.62%-103.71%(RSD=2.85%,n=6), 97.33%-102.67%(RSD=2.00%,n=6), 95.00%-99.33%(RSD=1.75%,n=6), 97.24%-104.93%(RSD=2.63%,n=6), 95.00%-97.50%(RSD=1.42%,n=6), 96.00%-102.00%(RSD=2.45%,n=6), respectively. CONCLUSIONS: The developed method is accurate, sensitive and reproducible, and it can be used for content determination of 10 lignanoids in Wuzhi tablets.
