The molecular constituents of Cirsium brachycephalum fruits were identified, quantified and isolated for the first time. The lignan glycoside tracheloside was the main compound, which was transformed quantitatively into its aglycone trachelogenin by endogenous enzymatic treatment of the fruit. Following this transformation by high performance liquid chromatography (HPLC) hyphenatedwith UV and mass spectrometry (MS) detections on a quantitative basis, the enzyme-hydrolyzed fruit was found to be the richest raw material containing trachelogenin (17.2 mg/g) reported to date. Thus, the enzyme-hydrolyzed fruitwas used to isolate trachelogenin using preparative HPLC in order to (1) unambiguously confirm its identity by gas chromatography-MS, nuclear magnetic resonance spectroscopy and optical rotation, and (2) investigate its in vitro antiproliferative activities against the SW480 colon adenocarcinoma cell line. Trachelogenin significantly affected the phosphorylation of key proteins such as β-Catenin, c-Myc and GSK3 in the β-Catenin signaling pathway in a concentration-dependent manner. These changes account for the antiproliferative effects of trachelogenin.
