TITLE:
摘要: 目的:建立同时测定独一味中山栀苷甲酯、木犀草素、芹菜素含量的方法。方法:采用高效液相色谱法。色谱柱为Diamonds C18,流动相为乙腈-0.1%磷酸溶液(梯度洗脱),流速为1.0 ml/min,检测波长为238 nm(山栀苷甲酯)、348 nm(木犀草素、芹菜素),柱温为25 ℃,进样量为10 μl。结果:山栀苷甲酯、木犀草素、芹菜素检测质量浓度线性范围分别3.08~308 μg/ml(r=0.999 8)、3.72~372 μg/ml(r=0.999 9)、2.92~292 μg/ml(r=0.999 9);精密度、稳定性、重复性试验的RSD<3.0%;加样回收率分别为95.38%~103.15%(RSD=1.85%,n=9)、 96.05%~102.66%(RSD=2.07%,n=9)、95.49%~103.59%(RSD=2.18%,n=9)。结论:该方法操作简便,精密度、稳定性、重复性好,可用于独一味中山栀苷甲酯、木犀草素、芹菜素含量的同时测定。
ABSTRACT: OBJECTIVE: To establish a method for the contents determination of dipsacoside B, luteolin and apigenin in Zang medicine Lamiophlomis rotata. METHODS: HPLC was performed on the column of Diamonds C18 with mobile phase of acetonitrile-0.1% phosphoric acid solution (gradient elution) at a flow rate of 1.0 ml/min, detection wavelength was 238 nm for dipsacoside B, 348 nm for luteolin and apigenin, column temperature was 25 ℃, and injection volume was 10 μl. RESULTS: The linear range was 3.08-308 μg/ml for dipsacoside B (r=0.999 8), 3.72-372 μg/ml for luteolin (r=0.999 9)and 2.92-292 μg/ml for apigenin(r=0.999 9); RSDs of precision, stability and reproducibility tests were lower than 3.0%; recoveries were 95.38%-103.15% (RSD=1.85%,n=9), 96.05%-102.66%(RSD=2.07%,n=9) and 95.49%-103.59%(RSD=2.18%,n=9). CONCLUSIONS: The method is simple with good precision, stability and reproducibility, and can be used for the simultaneous determination of dipsacoside B, luteolin and apigenin in Zang medicine L. rotata.
