Sumario:Natural plants are rich sources of various bioactive compounds. Consequently, the efficiently isolation of these bioactive components has always attracted considerable attention. Our work aims to demonstrate a framework for bioactivity guided isolation of potential effective compounds from the complex food materials. We demonstrated its application for isolation of phenolic compounds with anti-proliferative activity against colorectal cancer cells (CRCs) from Citrus aurantium L. Firstly, phenolic rich fraction was successfully identified as the main effective components that could simultaneously suppress the growth of CRCs and inhibit Wnt signaling. In order to obtain the bioactive phenolic constituents, a detailed study was performed by optimizing the purification conditions. Two phenolic rich fractions (40% and 60% ethanol elution fractions) were then obtained by AB-8 macroporous resins under optimized condition. Finally, the main components (65 compounds) were tentatively identified from the 40% ethanol eluant by ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UHPLC-Q-TOF/MS) analysis. Notably, there were five of the phytochemicals (Feruloylagmatine, Haploside C, Sagittatin A, Linderagalactone C and Koparin-2′-methyl ether) which were hitherto unidentified in Citrus aurantium L. fruit. In conclusion, this study showed that under the principle of bioactivity guided strategy, phenolic constituents with potential anti-CRCs activity were isolated from Citrus aurantium L.
