摘要: | 目的:建立同时测定三叶青块根中芦丁、异槲皮苷、山柰酚-3-O-芸香糖苷、紫云英苷、槲皮素和山柰酚含量的方法。方法:采用高效液相色谱(HPLC)法。色谱柱为Alliance SilGreen C18,流动相为0.2%磷酸水溶液-乙腈溶液(梯度洗脱),流速为1.0 mL/min,柱温为35 ℃,检测波长为360 nm,进样量为15 μL。结果:芦丁、异槲皮苷、山柰酚-3-O-芸香糖苷、紫云英苷、槲皮素和山柰酚的检测质量浓度线性范围分别为21.77~217.77、12.37~123.75、13.23~132.31、4.63~46.30、5.75~57.50、3.36~33.66 μg/mL(r均=0.999 9);检测限分别为0.217 8、0.123 8、0.066 2、0.046 3、0.191 7、0.112 3 μg/mL;定量限分别为0.435 6、0.247 5、0.165 4、0.154 3、0.575 0、0.421 2 μg/mL;精密度(n=6)、稳定性(24 h,n=7)、重复性(n=6)试验的RSD均≤3.20%;平均加样回收率分别为96.23%、86.88%、97.51%、97.67%、97.50%、87.46%,RSD分别为1.85%、1.90%、1.84%、1.87%、1.25%、2.01%(n=9)。结论:该方法快速、简便,可用于同时测定三叶青块根中芦丁、异槲皮苷、山柰酚-3-O-芸香糖苷、紫云英苷、槲皮素和山柰酚的含量。 |
ABSTRACT: | OBJECTIVE: To establish a method for simultaneous determination of rutin, isoquercitrin, kaempferol-3-O- rutinoside, daunorubicin, quercetin and kaempferol in the roots of Tetrastigma hemsleyanum. METHODS: HPLC method was adopted. The determination was performed on Alliance SilGreen C18 column with mobile phase consisted of 0.2% phosphoric acid solution-acetonitrile solution (gradient elution) at the flow rate of 1.0 mL/min. The detection wavelength was 360 nm and the column temperature was at 35 ℃. The sample size was 15 μL. RESULTS: The linear range of rutin, isoquercitrin, kaempferol-3- O-rutinoside, daunorubicin, quercetin and kaempferol were 21.77-217.77, 12.37-123.75, 13.23-132.31, 4.63-46.30, 5.75-57.50, 3.36-33.66 μg/mL (all r=0.999 9), respectively. limit of detection of them were 0.217 8, 0.123 8, 0.066 2, 0.046 3, 0.191 7, 0.112 3 μg/mL, respectively. limit of quantitation of them were 0.435 6, 0.247 5, 0.165 4, 0.154 3, 0.575 0, 0.421 2 μg/mL, respectively. RSDs of precision (n=6), stability (24 h, n=7) and reproducibility tests (n=6) were lower than 3.20%. The average recoveries of them were 96.23%, 86.88%, 97.51%, 97.67%, 97.50%, 87.46%, RSDs were 1.85%, 1.90%, 1.84%, 1.87%, 1.25%, 2.01% (n=9), respectively. CONCLUSIONS: The method is fast and simple, and could be applied for simultaneous determination of rutin, isoquercitrin, kaempferol-3-O-rutinoside, daunorubicin, quercetin and kaempferol in the roots of T. hemsleyanum. |
