目的 利用投影寻踪模型对不同生态型板蓝根药材的质量进行评价.方法 以甘肃产11份不同生态型板蓝根药材为评价样本,以板蓝根中所含表告依春、尿苷、鸟苷、腺苷、苯甲酸、水杨酸、靛蓝、靛玉红、醇溶性浸出物含量为评价指标,结合DPS V 9.50统计软件构建投影寻踪模型,对药材质量进行评价.结果 根据上述9个指标对板蓝根药材进行质量评价,得到11份不同生态型的板蓝根药材质量优劣的顺序:S2>S1>S9>S7>S8>S3>S5>S10>S11>S4>S6.结论 不同生态型板蓝根药材质量存在明显差异,以石家庄四倍体板蓝根质量最优.%Objective To evaluate the quality of Isatidis Radix from different ecotypes by using projection pursuit model. Methods Totally 11 batches of Isatidis Radix from different ecotypes in Gansu Province were used as evaluation samples. With the contents of epigoitrin, uridine, guanosine, adenosine, benzoic acid, salicylic acid, indigo, indirubin, and alcohol extract as evaluating indexes, combined with projection pursuit model established by DPS V 9.50 statistics software, the quality of Isatidis Radix was evaluated. Results Based on the evalution of nine main indexes, quality order of the 11 batches of Isatidis Radix was acquired: S2>S1>S9>S7>S8>S3>S5>S10>S11>S4>S6. Conclusion The projection pursuit model was available for the quality evaluation of different ecotype Isatidis Radix. The quality of Isatidis Radix from different ecotypes is different significantly, and the quality of tetraploid Isatidis Radix of Shijiazhuang is the best.
