                 Abstract:  Seven kind of new acetamide compounds  containing  capsaicin  moieties (Ⅰ~Ⅶ) were synthesized from
                 aromatic hydrocarbons with N-hydroxymethylacetamide via Friedel-Crafts alkylation reaction and characterized by IR
                    1
                 and  HNMR. Their bacteriostatic activities were evaluated by Escherichia coli and Staphylococcus aureus. Their algal
                 inhibition activities against Phaeodactylumtricornutum, Skeletonemacostatum and Chaetoceroscurvisetus were also evaluated.
                 The results showed that all of compounds exhibited good inhibition effects against two kinds of bacteria and three kinds
                 of  algae.  In  particular,  compound  Ⅶ(N-[2-hydroxy-5-(1-methyl-1-phenyl-ethyl)-benzyl]-acetamide)  had  the  best
                 inhibition effect. The minimal antibacterial concentration was 0.0625 g/L, and both bacteriostasic rate and alga growth
                 inhibition rate were over 90% at 3 g/L.
