TITLE:
摘要: 目的:建立同时测定野生刺五加果和根中5种主要成分紫丁香苷、绿原酸、刺五加苷E、异嗪皮啶和槲皮素-3-鼠李糖苷含量的方法。方法:采用超高效液相色谱法。色谱柱为Waters ACQUITY UPLC HSS T3,流动相为乙腈-0.3%磷酸(梯度洗脱),流速为0.2 ml/min,检测波长为300 nm,柱温为30 ℃,进样量为10 μl。结果:紫丁香苷、绿原酸、刺五加苷E、异嗪皮啶、槲皮素-3-鼠李糖苷检测质量浓度线性范围分别为24.56~184.2 μg/ml(r=0.999 3)、18.454~138.405 μg/ml(r=0.999 3)、8.416~63.12 μg/ml(r=0.999 7)、3.286~24.645 μg/ml(r=0.999 3)、2.522~18.915 μg/ml(r=0.999 8);精密度、稳定性、重复性试验的RSD<1%。刺五加果中上述5种成分的加样回收率分别为99.14%~100.50%(RSD=0.48%,n=6)、99.03%~100.45%(RSD=0.50%,n=6)、 99.22%~100.44%(RSD=0.44%,n=6)、99.80%~100.80%(RSD=0.44%,n=6)、 99.76%~101.10%(RSD=0.51%,n=6);刺五加根中上述前4种成分的加样回收率分别为99.21%~101.20%(RSD=0.73%,n=6)、99.81%~101.20%(RSD=0.52%,n=6)、100.00%~101.80%(RSD=0.62%,n=6)、99.22%~100.40%(RSD=0.47%,n=6) 。结论:该方法操作简便、稳定、重复性好,可用于野生刺五加果和根中紫丁香苷、绿原酸、刺五加苷E、异嗪皮啶和槲皮素-3-鼠李糖苷含量的同时测定。
ABSTRACT: OBJECTIVE:To establish a method for the 5 main components (original syringin, chlorogenic acid, eleutheroside E, isofraxidin and quercetin-3-rhamnoside) in the fruits and roots of wild Acanthopanax senticosus. METHODS:UPLC was performed on the column of Waters ACQUITY UPLC HSS T3 with mobile phase of acetonitrile-0.3% phosphoric acid (gradient elution) at a flow rate of 0.2 ml/min. Detection wavelength was 300 nm, column temperature was 30 ℃,and injection volume was 10 μl. RESULTS: The linear range was 24.56-184.2 μg/ml for syringin (r=0.999 3), 18.454-138.405 μg/ml for chlorogenic acid (r=0.999 3),8.416-63.12 μg/ml for eleutheroside E (r=0.999 7), 3.286-24.645 μg/ml for isofraxidin (r=0.999 3) and 2.522-18.915 μg/ml for quercetin-3-rhamnoside(r=0.999 8); RSDs of precision, stability and reproducibility tests were lower than 1%; recoveries were 99.14%-100.50%(RSD=0.48%,n=6)for syringing in the fruits of A. senticosus、99.03%-100.45%(RSD=0.50%,n=6) for chlorogenic acid in the fruits of A. senticosus、99.22%-100.44%(RSD=0.44%,n=6)for  eleutheroside E in the fruits of A. senticosus、99.80%-100.80%(RDS=0.44%,n=6)for isofraxidin in the fruits of A. senticosus、 99.76%-101.10%(RSD=0.51%,n=6)for quercetin-3-rhamnoside in the fruits of A. senticosus;99.21%-101.20%(RSD=0.73%,n=6) for syringing in the root of A. senticosus、99.81%-101.20%(RSD=0.52%,n=6) for chlorogenic acid in the root of A. senticosus、 100.00%-101.50%(RSD=0.62%,n=6)for  eleutheroside E in the root of A. senticosus、99.22%-100.40%(RSD=0.47%,n=6)for  isofraxidin in the root of A. senticosus. CONCLUSIONS:The method is simple and stable with good reproducibility, and can be used for the simultaneous determination of original syringin, chlorogenic acid, eleutheroside E, isofraxidin and quercetin-3-rhamnoside in the fruits and root of wild A. senticosus.
