Comparison of Crude and Wine-Steamed Corni Fructus Based on UPLC-Q-TOF-MS Combined with Pharmacodynamics Screening

Introduction: The dry ripe sarcocarp of Cornus officinalis Sieb.et Zucc (in Chinese Shanyurou) has the properties of tonifying the liver and kidney. Wine-steamed Corni Fructus, as the main processed product from Corni Fructus, is widely used in traditional Chinese clinical medicine. This article aims to study the Corni Fructus composition changes when wine-steamed processed and to discuss the optimal processing technology of Corni Fructus combined with pharmacological experiments. Methods: The differences between Corni Fructus and wine-steamed Corni fructus constituents were analyzed by ultra-performance liquid chromatography-tandem mass spectrometry. The effects of Corni Fructus and wine-steamed Corni Fructus with different processing times were studied from the aspects of immune activity, liver protection, and kidney yin deficiency. Results: A total of 132 compounds were identified in the wine-steamed process of Corni Fructus. There were no significant differences in immune function, liver protection, and kidney yin deficiency of Corni Fructus with different processing times. However, the effects of Corni Fructus processed by wine-steaming were significantly enhanced in all aspects. Conclusion: The wine-steamed Corni Fructus chemical composition may be the material basis for enhancing liver and kidney function. After processing, Corni Fructus can enhance immune function, liver protection function, and liver and kidney toning function.
