摘 要 目的:建立同时测定正心降脂片中葛根素、3′-甲氧基葛根素、大豆苷、芦丁、橙皮苷、丹酚酸A、槲皮素等7种成分含量的
方法,并进行聚类热图分析。方法:采用高效液相色谱法。色谱柱为Kromasil C18,流动相为乙腈-0.1%甲酸溶液(梯度洗脱),流速
为0.8 mL/min,检测波长为280 nm,柱温为25 ℃,进样量为10 μL。以含量数据为对象,采用Hiplot科研绘图平台绘制聚类热图。
结果:葛根素、3′-甲氧基葛根素、大豆苷、芦丁、橙皮苷、丹酚酸A、槲皮素检测质量浓度的线性范围分别为17.00~170.00(r=0.999 9)、
5.14~51.40(r=0.999 8)、3.00~30.00(r=0.999 8)、153.00~1 530.00(r=0.999 9)、7.88~78.75(r=0.999 8)、2.85~28.50(r=
0.999 9)、11.34~113.40 μg/mL(r=0.999 8)。精密度、稳定性(24 h)、重复性试验的 RSD 均小于 2%;平均加样回收率分别为
99.58%(RSD=0.83%,n=6)、100.31%(RSD=1.17%,n=6)、100.61%(RSD=1.08%,n=6)、100.05%(RSD=0.82%,n=6)、
100.31%(RSD=1.38%,n=6)、100.31%(RSD=0.85%,n=6)、99.85%(RSD=1.01%,n=6)。10批样品中上述成分的含量分别
为 7.262 5~8.941 5、2.464 9~3.068 9、1.478 9~1.883 4、58.632 8~79.408 3、3.569 4~4.500 6、1.077 6~1.341 5、1.139 7~5.957 0
mg/g。聚类热图分析结果显示,10批样品可聚为4类,其中S1~S3聚为一类、S4聚为一类、S5~S6聚为一类、S7~S10聚为一类。
结论:所建含量测定方法操作简便、准确性高、专属性强,结合聚类热图分析可用于正心降脂片的质量控制;不同批次样品的质量
存在一定差异。

ABSTRACT OBJECTIVE: To establish the method for the content determination of 7 components, such as puerarin,
3′-methoxypuerarin,daidzein,rutin,hesperidin,salvianolic acid A and quercetin,in Zhengxin jiangzhi tablets,and conduct
cluster heatmap analysis. METHODS:HPLC method was adopted. The separation was performed on Kromasil C18 column with
mobile phase consisted of acetonitrile-0.1% formic acid solution(gradient elution)at the flow rate of 0.8 mL/min. The detection
wavelength was set at 280 nm,and the column temperature was 25 ℃. The sample size was 10 μL. Taking the content data as the
object,the cluster heatmap was drawn by Hiplot scientific research mapping platform. RESULTS:The linear range of puerarin,
3′-methoxypuerarin,daidzein,rutin,hesperidin,salvianolic acid A and quercetin were 17.00-170.00(r=0.999 9),5.14-51.40(r=
0.999 8),3.00-30.00 (r=0.999 8),153.00-1 530.00 (r=0.999 9),7.88-78.75 (r=0.999 8),2.85-28.50 (r=0.999 9) and
11.34-113.40 μg/mL(r=0.999 8),respectively. RSDs of precision,stability(24 h)and repeatability tests were all less than 2%;
the average recoveries were 99.58%(RSD=0.83%,n=6),100.31%(RSD=1.17%,n=6),100.61%(RSD=1.08%,n=6),
100.05%(RSD=0.82%,n=6),100.31%(RSD=1.38%,n=6),100.31%(RSD=0.85%,n=6),99.85%(RSD=1.01%,
n=6),respectively. The contents of above components in 10 batches of samples were 7.262 5-8.941 5,2.464 9-3.068 9,1.478 9-
1.883 4,58.632 8-79.408 3,3.569 4-4.500 6,1.077 6-1.341 5,1.139 7-5.957 0 mg/g,respectively. Results of cluster heatmap
analysis showed that 10 batches of samples could be divided into 4 categories,including S1-S3 as one category,S4 as one
category,S5-S6 as one category and S7-S10 as one category. CONCLUSIONS:The established method is simple,accurate and
specific,which can be used for the quality control of Zhengxin jiangzhi tablets,combined with cluster heatmap analysis. There are
some differences in the quality of different batches of samples.
