A substituent group of a suitable size and the trimethoxybenzene had a certain influence on the bioactivity of the flavonoid salicylatederivatives. Compound 2 and its salicylatederivatives 7a–7g containing the trimethoxybenzene exhibited more antiproliferative activity. Among them, compound 7g displayed the most potent antiproliferative activity against MGC-803 cells and MFC cells with the concentration

Although berberine (BBR) shows antioxidantactivity, its activity is limited. We synthesized 9-O-benzoic acid berberine derivatives, and their antioxidantactivities were screened via ABTS, DPPH, HOSC and FRAP assays. The para-position was modified with halogen elements on the benzoic acid ring, which led to an enhanced antioxidantactivity and the substituent on the ortho-position was found to be
