Cornus officinalis, a kind of edible herbal medicine, has been widely used in the protection of liver and kidney due to its medicinal and nutritional effect. Its anti-inflammatory, anti-tumor, and anti-oxidant activities can be enhanced by wine-steamed (WS) processing. Based on the activations of hepatic stellate cells-T6 (HSC-T6) and HK-2, our study used single-factor plus orthogonal design to investigate the anti-fibrosis of C. officinalis processed with steamed (S), high-pressure steamed (HPS), WS, high-pressure wine-steamed (HPWS), wine-dipped (WD), and wine-fried (WF). The chemical constituents in processed C. officinalis with higher anti-fibrotic activities were detected by ultra-high performance liquid chromatography coupled with hybrid triple quadrupole time-of-flight mass spectrometry (UHPLC-Q-TOF-MS/MS). Results showed that C. officinalis with HPWS significantly inhibited the activations of HSC-T6 and HK-2. Moreover, compounds in C. officinalis with HPWS were obtained via UHPLC-Q-TOF-MS/MS, indicating that 27 components were changed compared with raw C. officinalis. These results demonstrated that HPWS is the optimal processing technology for anti-fibrosis of C. officinalis. Graphical Abstract The processing technology of C. officinalis was optimized in terms of its anti-fibrotic activity. Differences in its chemical composition after the preparation were detected by UHPLC-Q-TOF-MS/MS. These results provide material basis for further exploring the role of C. officinalis in liver and kidney protection.
