Figure 3From: Chemical changes of Angelicae Sinensis Radix and Chuanxiong Rhizoma by wine treatment: chemical profiling and marker selection by gas chromatography coupled with triple quadrupole mass spectrometryPCA projection plots for ASR and CR. (A) Score plots for crude ASR, wine-treated ASR, crude CR and wine-treated CR using common components as the input data. (B) Score plots for crude and wine-treated ASR and CR, as in (A), using the peak areas of five chemical markers, namely ferulic acid, butylphthalide, Z-butylidenephthalide, senkyunolide A and Z-ligustilide.Back to article page
