Its structure was characterized by 1H NMR, 13C NMR and HR-MS. The phloretin, compound 1, resveratrol and acetylated resveratrol were determined by comparing them with paclitaxel. Anti-tumor activity of alcohol on SPC-A1, EC109, A549, MCF-7 and MDA-MB-231 cell lines. Compound 1 showed better antitumor activity than docetaxel against A549 tumor cells. %K 3-[2-(4-Hydroxy-Phenyl)-Ethyl]-Benzo[< %K i> %K d< %K /i> %K ] Isoxazole-4 %K 6-Diol %K Synthesis %K Antitumor Activity %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=122846
