Abstract

The antibacterial activity and application of puchiin extraction from the processed wastes of Eleocharis dulcis were studied.The results showed that puchiin had inhibition activity to Escherichia coli,Staphylococcus aureus,Micrococcus luteus and Bacillus subtilis.Among the four bacteria,the inhibition activity to S.aureus was the highest.The inhibition activity was better than 1% potassium sorbate solution on E.coli,S.aureus and M.luteus except B.subtilis.Puchiin could effectively control the spoilage caused by Rhizopus nigrican and Alternaria alternate.However,the inhibition activity to A.alternata was better than that of R.nigrican.
