Identification and analysis of anti‐tumor effective substances in Yangzheng Mixture

Abstract

AbstractYangzheng Mixture is a traditional Chinese medicine used in clinical practice as an adjuvant therapy for tumors. However, little is known about its active components in tumor treatment. The purpose of this study was to explore the potential anti‐tumor components of Yangzheng Mixture to better promote its clinical application. Using LC–MS/MS, 43 components were detected in concentrated Yangzheng Mixture. Six components, comprising astragaloside, calycosin, formononetin, isoquercitrin, ononin, and calycosin‐7‐O‐β‐D‐glucoside, were identified in rat plasma. The cancer cell absorption assay showed that the intracellular concentration of four components, calycosin, calycosin‐7‐O‐β‐D‐glucoside, formononetin, and ononin, increased with extended incubation time and demonstrated potential anti‐tumor effects. The MTT assay results confirmed that Yangzheng Mixture inhibited different tumor cells proliferation. Additionally, the colony formation assay, flow cytometry analysis and wound healing displayed that Yangzheng Mixture and a combination of four components could inhibit colony formation, arrest the cell cycle and impair cell migration of tumor cells, including HCT‐116, MHCC‐97L, MCF‐7 and NCI‐H1299. In summary, our study highlighted the plausible application of Yangzheng Mixture as a potential adjuvant treatment for tumors. Furthermore, it identified effective anti‐tumor components and provided evidences for the further clinical application of Yangzheng Mixture.
