Analysis on the quality of wild and different cultivation methods of Sanghuang porus vaninii (Ljub.) L.W. Zhou & Y.C. Dai / 国际中医中药杂志

ABSTRACT

Objective:To compare and evaluate the quality of wild and different cultivation methods of Sanghuang porus vaninii (Ljub.) L.W. Zhou & Y.C. Dai through analysis on UPLC characteristic atlas and multi-component content determination results. Methods:UPLC was used to establish the characteristic chromatogram and multi-component content determination method of Sanghuang porus vaninii (Ljub.) L.W. Zhou & Y.C. Dai, and clustering analysis, orthogonal partial least squares - discriminant analysis method were used for chemical pattern recognition analysis. Results:The results showed that there were 10 common peaks in 18 batches of Sanghuang porus vaninii (Ljub.) L.W. Zhou & Y.C. Dai. Five components were identified, erythrothioneine(peak 1), protocatechuic acid (peak 2), protocatechualdehyde (peak 3), caffeic acid (peak 4) and Hispidin (peak 5). HCA and OPLS-DA could distinguish Sanghuang porus vaninii (Ljub.) with different cultivation methods. Conclusion:Sanghuang porus vaninii (Ljub.) L.W. Zhou & Y.C. Dai in wood is closer to wild Sanghuang porus vaninii (Ljub.) L.W. Zhou & Y.C. Dai than in substitute cultivation. The UPLC characteristic atlas and multi-component content determination method established in this study can provide reference for the quality evaluation of Sanghuang porus vaninii (Ljub.) L.W. Zhou & Y.C. Dai.
