Variation of Saponins in Sanguisorba officinalis L. before and after Processing ( Paozhi ) and Its Effects on Colon Cancer Cells In Vitro.

The incidence of colon cancer is increasing year over year, seriously affecting human health and quality of life in recent years. However, traditional Chinese medicine (TCM) has been utilized for the treatment of colon cancer. Saponins (), the potential compound of TCM, displays multiple biological activities in colon cancer treatment. In our study, ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) combined with multivariate statistical analysis were performed to analyze and identify raw and processed saponins. Then, MTT and cell migration assays were used to preliminarily explore the effects of saponins in vitro on colon cancer cells. The results showed that 29 differential saponins compounds under were identified by UHPLC-MS/MS. Moreover, in vitro validation showed that better inhibited the proliferation and migration of colon cancer cells than . This study provides a basis for the determination of the chemical fundamentals of the efficacy changes during through inferring the changes in saponin components and its possible transformation mechanisms before and after processing . Meanwhile, it also provides new insights into potential bioactive ingredients for the treatment of colon cancer.
