中文摘要: 目的:建立同时测定温经汤中10种活性成分(芍药内酯苷、芍药苷、β-蜕皮甾酮、甘草苷、阿魏酸、甘草素、肉桂酸、桂皮醛、丹皮酚和甘草酸铵)含量的方法。方法:采用高效液相色谱(HPLC)法。色谱柱为Kromasil C18,流动相为乙腈-0.1%磷酸水溶液(梯度洗脱),流速为1.0 mL/min,双波长切换检测(0~25 min为240 nm,检测芍药内酯苷、芍药苷、β-蜕皮甾酮、甘草苷、阿魏酸;25~65 min为275 nm,检测甘草素、肉桂酸、桂皮醛、丹皮酚、甘草酸铵),柱温为25 ℃,进样量为20 μL。结果:芍药内酯苷、芍药苷、β-蜕皮甾酮、甘草苷、阿魏酸、甘草素、肉桂酸、桂皮醛、丹皮酚、甘草酸铵的检测质量浓度线性范围分别为4.04~80.80、19.32~368.40、2.62~52.40、17.52~350.40、2.07~41.40、4.02~80.40、0.56~11.20、1.69~33.80、2.18~43.60、72.10~1 442.00 μg/mL(r均≥ 0.999 6),检测限分别为0.06、0.03、0.04、0.06、0.07、0.05、0.04、0.06、0.07、0.09 μg/mL,定量限分别为0.17、0.09、0.13、0.19、0.20、0.18、0.11、0.15、0.18、0.25 μg/mL,精密度、重复性、稳定性(24 h)试验的RSD均<3.5%(n=6~7),各种成分的平均加样回收率为97.72%~100.60%(RSD 为0.80%~2.49%,n=6)。结论:建立的HPLC法准确可靠、专属性好,可用于温经汤中芍药内酯苷等10种活性成分含量的同时测定。
英文摘要: OBJECTIVE: To establish a method for simultaneous determination of 10 active components (albiflorin, paeoniflorin, β-ecdysterone, liquiritin, ferulic acid, liquiritigenin, cinnamic acid, cinnamaldehyde, paeonol and ammonium glycyrrhetate) in Wenjing decoction. METHODS: HPLC method was adopted. The determination was performed on Kromasil C18 column with mobile phase consisted of acetonitrile-0.1% phosphoric acid water solution (gradient elution) at the flow rate of 1.0 mL/min, in dual wavelength switching detection (0-25 min, 240 nm for albiflorin, paeoniflorin, β-ecdysterone, liquiritin, ferulic acid; 25-65 min, 275 nm for liquiritigenin, cinnamic acid, cinnamaldehyde, paeonol, ammonium glycyrrhetate). The column temperature was set at 25 ℃, and sample size was 20 μL. RESULTS: The linear range of albiflorin, paeoniflorin, β-ecdysterone, liquiritin, ferulic acid, liquiritigenin, cinnamic acid, cinnamaldehyde, paeonol and ammonium glycyrrhetate were 4.04-80.80, 19.32-368.40, 2.62-52.40, 17.52-350.40, 2.07-41.40, 4.02-80.40, 0.56-11.20, 1.69-33.80, 2.18-43.60 and 72.10-1 442.00 μg/mL (all r≥0.999 6), respectively. The limits of detection were 0.06, 0.03, 0.04, 0.06, 0.07, 0.05, 0.04, 0.06, 0.07, 0.09 μg/mL, respectively. The limits of quantitation were 0.17, 0.09, 0.13, 0.19, 0.20, 0.18, 0.11, 0.15, 0.18, 0.25 μg/mL, respectively. RSDs of precision, reproducibility and stability tests (24 h) were all lower than 3.5% (n=6-7). The average recovery rates were 97.72%-100.60% with the RSDs of 0.80%-2.49% (n=6). CONCLUSIONS: The established HPLC method is accurate, reliable and specfic, and suitable for simultaneous determination of 10 active components as albiflorin in Wenjing decoction.
