,流动相为乙腈-0.1%磷酸溶液(梯度洗脱),流速为0.3 mL/min,柱温为30 ℃,进样量为5 μL。结合主成分分析与聚类分析对含量测定结果进行综合分析,并对不同企业样品进行质量评价。
结果
2
上述11种成分在各自检测质量浓度范围内线性关系均良好(
r
≥0.999 3),精密度、重复性、稳定性试验的RSD均小于3%(
n
均为6),平均加样回收率为96.82%~98.92%(RSD≤1.74%,

结论
2
所建UPLC法稳定、可靠,可用于复方龙胆碳酸氢钠片中10种大黄蒽醌类成分及土大黄苷的含量测定。
OBJECTIVE
2
To establish a method for the simultaneous determination of 10 rhubarb anthraquinones in Compound gentian sodium bicarbonate tablets and the content of rhaponticin,which are the characteristic components of artifacts,and to use the method to evaluate the quality of compound preparation containing
Rheum officinale
.
METHODS
2
The ultra-performance liquid chromatography (UPLC) method was adopted to determine the contents of 10 rhubarb anthraquinones (aloe-emodin

column with a mobile phase consisted of acetonitrile-0.1% phosphoric acid solution (gradient elution) at a flow rate of 0.3 mL/min; the column temperature was set at 30 ℃,and the injection volume was 5 μL. Combining principal component analysis and cluster analysis to synthesize the results of content determination,the quality of samples from different manufacturers was evaluated.
RESULTS
2
All of above 11 components showed favorable linear relationships with peak areas in their respective mass concentration ranges (
r
≥0.999 3),with RSDs of precision,repeatability and stability less than 3% (
n
=6); average sample recoveries ranged 96.82%-98.92% (RSD≤1.74%,
n
=6); their contents were 0.011 7-0.252 0,0-0.323 3,0.131 3-1.236 6,0.081 1-1.056 2,0.015 2-0.189 8,0.001 8-0.152 3,0-0.255 2,0.001 9-0.223 4,0.054 3-0.303 0,0.022 7-0.172 2,0-2.835 9 mg/g,respectively. The cumulative variance contribution of the first three principal components was 95.533%; the 40 batches of samples can be clustered into 4 categories:samples from enterprises a and d were in a category of their own,samples from enterprises f,b,g and e were in a category,and samples from enterprises c and h were in a category. There were large differences in the content of rhubarb anthraquinone in the samples from 8 manufacturers,and rhaponticin was only detected in the sample from one enterprise.
CONCLUSIONS
2
Established UPLC method is stable and reliable; it can be used for the content determination of 10 rhubarb anthraquinones and rhaponticin in Compound gentian sodium bicarbonate tablets.
