Fresh Dendrobium officinale juice (FDOJ) changes color from green to purple after processing; however, the mechanism behind this is unknown. In this study, untargeted and targeted metabolomics were used to analyze pigment-related metabolites. The results showed that the content of delphinidin-type anthocyanin more than doubled in FDOJ after processing. Correlation analysis revealed that major substances in the anthocyanin biosynthesis pathway, including phenylalanine, cinnamic acid, and naringen
