TITLE: | |
摘要: | 目的:建立同时测定蒙药森登-4汤散中7种抗风湿活性成分儿茶素、栀子苷、二氢杨梅素、花旗松素、芦丁、杨梅素和槲皮素含量的方法。方法:采用高效液相色谱-二极管阵列检测法(HPLC-DAD)。色谱柱为Sil Green C18,流动相为乙腈-0.1%磷酸溶液(梯度洗脱),流速为1 mL/min,检测波长为238 nm,柱温为30 ℃,进样量为10 μL。结果:儿茶素、栀子苷、二氢杨梅素、花旗松素、芦丁、杨梅素和槲皮素检测质量浓度的线性范围分别为8.590~2 290、10.56~3 901、13.00~3 958、8.815~564.2、4.030~257.8、8.130~750.5、7.075~454.2 μg/mL(r≥0.999 1 );检测限分别为0.429 5、0.264 0、0.325 0、0.220 4、0.201 5、0.203 2、0.176 9 μg/mL,定量限分别为 1.030、1.321、1.302、1.397、1.637、0.813 0、0.707 5 μg/mL;精密度、稳定性(48 h)、重复性试验的RSD均小于2.0%(n=6);平均加样回收率分别为96.24%~99.28%,RSD分别为1.03%~1.63%(n=6)。结论:该方法简便、准确、重复性良好,可用于同时测定蒙药森登-4汤散中儿茶素、栀子苷、二氢杨梅素、花旗松素、芦丁、杨梅素和槲皮素的含量。 |
ABSTRACT: | OBJECTIVE: To establish a method for simultaneous determination of 7 kinds of anti-rheumatic active ingredients in Mongolian medicine Sendeng-4 decoction powder, such as catechin, jasminoidin, dihydromyricetin, texifolin, rutin, myricetin and quercetin. METHODS: HPLC-DAD method was adopted. The determination was performed on Sil Green C18 column with mobile phase consisted of acetonitrile-0.1% phosphoric acid solution (gradient elution) at the flow rate of 1 mL/min. The detection wavelength was set at 238 nm, and column temperature was 30 ℃. The sample size was 10 μL. RESULTS: The linear range of catechin, jasminoidin, dihydromyricetin, texifolin, rutin, myricetin and quercetin were 8.590-2 290, 10.56-3 901, 13.00-3 958, 8.815-564.2, 4.030-257.8, 8.130-750.5, 7.075-454.2 μg/mL (r≥0.999 1), respectively; the limits of detection were 0.429 5, 0.264 0, 0.325 0, 0.220 4, 0.201 5, 0.203 2, 0.176 9 μg/mL, respectively; the limits of quantification were 1.030, 1.321, 1.302, 1.397, 1.637, 0.813 0, 0.707 5 μg/mL, respectively. RSDs of precision, stability (48 h) and repetition tests were all lower than 2.0% (n=6). The average recoveries were 96.24%-99.28% (RSD=1.03%-1.63%, n=6). CONCLUSIONS: The established method is simple, accurate and reproducible, and can be used for simultaneous determination of catechin, jasminoidin, dihydromyricetin, texifolin, rutin, myricetin and quercetin in Mongolian medicine Sendeng-4 decoction powder. |
