    摘要:

    目的建立一测多评法同时测定复方金线莲口服液中尿苷、鸟苷、赤芝酸C和灵芝酸A的含量,并验证该方法的准确性。方法采用HPLC法,色谱条件:ZOBAX SB-Aq C 18柱(4.6 mm×250 mm,5 μm),流动相:乙腈-乙酸铵(含13 mmol/L乙酸铵、pH=4)为流动相,梯度洗脱; 流速1.0 mL/min,检测波长254 nm,柱温 30 ℃,进样量20 μL。以鸟苷为参照物,建立其对尿苷、赤芝酸C和灵芝酸A的相对校正因子,并用该校正因子进行尿苷、赤芝酸C、灵芝酸A的含量计算,其定量结果与外标法定量结果比较,以验证一测多评法的准确性和可行性。结果尿苷、鸟苷、赤芝酸C、灵芝酸A分别在2~40,3~60,1~20和 1~160 μg/mL范围内呈现良好线性关系(均为 r2=0.999 9); 尿苷、赤芝酸C、灵芝酸A的相对校正因子分别为1.02,0.34,0.40; 一测多评法的计算结果和外标法实测值之间无显著差异(S=0.999 9); 尿苷、鸟苷、赤芝酸C、灵芝酸A平均加样回收率(n=3)分别为94.5%,104.0%,86.6%和105.0%。结论建立的一测多评法可作为测定复方金线莲口服液中4种有效成分含量的测定方法。

    Abstract:

    ObjectiveTo establish a quantitative analysis of multi-components by single-marker(QAMS)for simultaneously determining uridine, guanosine, lucidenic acid C and ganoderic acid A in Compound Anoectochilus roxburghii(Wall.)Lindl (A.roxburghii)oral liquid, and validate its feasibility for quality evaluation.MethodsThe contents of uridine, guanosine, lucidenic acid C and ganoderic acid A in oral liquid were determined by high-performance liquid chromatography(HPLC), and the separation was performed on ZOBAX SB-Aq C 18 column(4.6 mm×250 mm, 5 μm).The mobile phase comprised acetonitrile-ammonium acetate(13 mmol/L ammonium acetate, pH=4)with the gradient elution and at a flow rate of 1.0 mL/min.The wavelength for detection and column temperature were set at 254 nm and 30 ℃, respectively.The injection volume was 20 μL.Using guanosine as the internal reference substance the relative correction factors(RCFs)for uridine, lucidenic acid C and ganoderic acid A was determined by HPLC-UV with good reproducibility.To verify the accuracy and feasibility of the QAMS, the contents of four active ingredients were also determined by the external standard method(ESM).ResultsThe linear range of uridine, guanosine, lucidenic acid C and ganoderic acid A were 2-40 μg/mL( r2=0.999 9), 3-60 μg/mL(r2=0.999 9), 1-20 μg/mL(r2=0.999 9)and 1-160 μg/mL( r2=0.999 9), respectively.RCFs of uridine, lucidenic acid C and ganoderic acid A with reference to guanosine were 1.02, 0.34, 0.40, respectively.No significant differences between the quantitative results of QAMS and ESM were observed(S=0.999 9).The average recoveries(n=3)were 94.5%, 104.0%, 86.6% and 105.0%, respectively.ConclusionThe established QAMS cab be used for the determination of four active ingredients in compound A.roxburghii oral liquid.
