| Title | Quantitative structure-retention relationships for mycotoxins and fungal metabolites in LC-MS/MS. | | Author(s) | Ji C, Li Y, Su L, Zhang X, Chen X | | Institution | Department of Chemistry, Lanzhou University, Lanzhou, Gansu, P. R.

Heuristic method and radial basis function neural networks (RBFNN) were utilized to construct the linear and non-linear QSRR models, respectively. The optimal QSRR model was developed based on a 5-21-1 RBFNN architecture using molecular descriptors calculated from molecular structure alone. The RBFNN model gave a square of correlation coefficient (R(2)) of 0.8709 and root mean square error of 1.2892 for the test set. This article provided a useful tool for predicting the t(R) of other mycotoxins when experiment data are unknown. | | Language | ENG | | Pub Type(s) | JOURNAL ARTICLE
