Six of them are confirmed by IR,1H NMR,13C NMR and elementary analyses. The preliminary antibacterial activities against staphylococcus albus and escherichia coli are studied. The result show that all the deprotected products has a good antibacterial ability to the two bacterias,while the products protected by acetyl show no activity.展开更多
