Functional Metabolomics and Chemoproteomics Approaches Reveal Novel Metabolic Targets for Anticancer Therapy

Ophiopogonis Radix, also known as Maidong in Chinese, is largely produced in the Sichuan and Zhejiang provinces: “Chuan-maidong (CMD)” and “Zhe-maidong (ZMD),” respectively. This study aimed to distinguish and evaluate the quality of CMD and ZMD. In this study, the tubers of CMD and ZMD were investigated using UPLC-Q/TOF-MS, GC-MS, and LC-MS methods, respectively. Overall, steroidal saponins, homoisoflavonoids, amino acids, and nucleosides were quickly identified. Furthermore, multivariate statistical analysis revealed that CMD and ZMD could be separated. Moreover, CMD showed higher levels of 4-aminobutanoic acid, glycine, l-proline, monoethanolamine, and serine than ZMD. Besides, the levels of chlorogenic acid, traumatic acid, cytidine, cadaverine, pyridoxine 5-phosphate, glutinone, and pelargonidin 3-O-(6-O-malonyl-β-d-glucoside) were remarkably higher in ZMD than in CMD. Furthermore, these different constituents were mainly associated with galactose metabolism; starch and sucrose metabolism; cysteine and methionine metabolism; valine, leucine, and isoleucine biosynthesis; and glycerophospholipid metabolism. In general, these results showed many differences between the bioactive chemical constituents of Ophiopogon japonicus from different production areas, where ZMD performed better in the quality assessment than CMD, and that UPLC-Q/TOF-MS, GC-MS, and LC-MS are effective methods to discriminate medicinal herbs from different production areas.
