摘 要:建立了RP-HPLC法同时测定菟丝子中6种活性成分,金丝桃苷、异槲皮苷、紫云英苷、山奈酚、槲皮素和异鼠李素的含量。方法:采用高效液相色谱法,色谱柱为Diamonsil-C18(5μm, 4.6mm×250mm)色谱柱;以乙腈(A)-0.1%磷酸水(B)为流动相梯度洗脱(0~20min,15%A→28%A;20~30min,28%A→68%A;30~40min,68%A),流速为1.0mL·min^-1,进样量为10μL,柱温为30℃,检测波长为360nm。结果:6种成分在相应的线性范围内线性关系良好。精密度的RSD为0.73%~1.98%;加样回收率为95.37%~108.00%,RSD值为2.79%~3.31%;稳定性的RSD为0.64%~2.71%。结论:9批不同产地得菟丝子药材均含有所测的6种活性成分,但含量差异较大。该方法专属性强,稳定可靠,可用于菟丝子中6种活性成分的含量测定。Objective: A RP-HPLC method for simultaneous determination of six active components(hyperoside, isoquercitrin, astragalin, quercetin, kaempferol and isorhamnetin) in Cuscuta chinensis was established.Methods: High performance liquid chromatography method, This method use a Diamonsil-C18(5μm, 4.6 mm ×250 mm)as chromatographic column;mobile phase: acetonitrile(A)-0.1% phosphoric acid water(B), gradient elution(0~20 min, 15%A→28%A;20~30 min, 28%A→68%A;30~40 min, 68%A). The flow rate was set at 1.0 mL·min^-1;the sample size is 10μL;column temperature is 25℃;detection wavelength is 360 nm. Result: Six active components in the corresponding linear range were showing good linear relationship. The precision of RSD is 0.73%~1.98%;The sample recovery is 95.37%~108.00% and RSD is 2.79%~3.31%;The RSD of stability is 0.64%~2.71%. Conclusion: The 9 batches of Cuscuta chinensis from different habitats contain 6 active components, but the content is quite different. The method is specific, stable and reliable. It can be used to determine the content of 6 active components in Cuscuta chinensis.
