摘　　要：建立玄参对照提取物制备工艺并进行标定,探讨其替代相应对照品在玄参药材质量控制中应用的可行性。采用溶剂提取法和色谱分离技术制备玄参对照提取物,以哈巴苷、安格洛苷C和哈巴俄苷对照品为对照,对玄参对照提取物进行含量标定。分别以已知含量的玄参对照提取物和哈巴苷、安格洛苷C、哈巴俄苷3个对照品为对照,建立玄参药材HPLC含量测定方法,测定玄参药材中3种成分的含量,采用t检验法对2种方法所得结果进行比较。以玄参对照提取物为对照,哈巴苷、安格洛苷C和哈巴俄苷进样量在各自范围内与峰面积呈良好的线性关系(r≥0.999 8),平均回收率为98.55%~100.6%。t检验结果显示,2种方法测定的哈巴苷、安格洛苷C、哈巴俄苷含量P分别为0.493,0.155,0.171,表明2种含量测定方法无显著性差异,玄参对照提取物可替代相应对照品用于玄参药材的质量控制。该研究结果为玄参药材的质量评价提供了新方法和新思路,为中药对照提取物在中药质量研究中的应用提供了科学依据。By establishing the preparation process of Scrophulariaceae Radix reference extract(SRRE) and calibrating it, we discussed its feasibility as a substitute for single reference substance in the quality control of Scrophulariae Radix. The SRREs were prepared by solvent extraction method and chromatographic separation technology, and then calibrated with the reference substances of harpagide, angoroside C and harpagoside. The HPLC content determination method of Scrophulariae Radixl was established with SRREs of the known content and the reference substances of harpagide, angoroside C and harpagoside respectively as the control ones. Then the content of three components in Scrophulariae Radix was determined, and the t-test method was used to compare the results of the two methods. With SRRE as references, harpagide, angoroside C and harpagoside were in a good linear relationship(r≥0.999 8) within each range, and the average recovery rate was 98.55% to 100.6%. The t-test results showed that the P values of two determination methods were 0.493, 0.155 and 0.171 for harpagide, angoroside C and harpagoside respectively, indicating no significant diffe-rence between the two methods of content determination. The SRRE can be used as a substitute for the reference in the quality control of Scrophulariaceae Radix. The SRRE can replace the corresponding reference substance for the quality control of Scrophulariae Radix. The results of this study provide new methods and new ideas for the quality evaluation of Scrophulariae Radix, and provide a scientific basis for the application of reference extracts in the quality research of traditional Chinese medicine.
