Abstract:
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.
