[Determination of ursolic acid of Liuwei Dihuangwan simulation samples by NIR].
OBJECTIVE
Determine the content of ursolic acid of Liuwei Dihuangwan.


METHODS
Using NIR with PLS, PCA-BPANN and WT-BPANN.


RESULTS
The predication recovery were 100.7%, 100.6%, 100.1%, and the RSD were 5.42%, 6.49%, 6.52% respectively.


CONCLUSIONS
NIR can be used in the determination of ursolic acid, which set up the foundation of on-line control of traditional Chinese medicine.
