Herbridge, 26 Dec. 2011_Crude extracts derived from Chaenomeles speciosa S.Nakai show broad-spectrum antimicrobial activity and can significantly inhibit five microorganisms such as Pseudomonas fluorescens, Escherichia coli, Bacillus subtilis, Staphylocaccus aureus and Micrococcus tetragenus, a new research published in the journal Science and Technology of Food Industry.
Reseachers from College of Tea and Food Science and Technology of Anhui Agricultural University used 95% ethanol or distilled water as solvent to get crude extracts from Chaenomeies by bain-marie vibration method. They used disk diffused tests to determine these two crude extracts' antimicrobial activity aganist Pseudomonas fluorescens, Escherichia coli, Bacillus subtilis, Staphylocaccus aureus and Micrococcus tetragenus as well as minimum inhibitory concentration and minimal bactericidal concentration. The results showed that these two crude extracts could inhibit the five microorganisms and 95% ethanol crude extract is superior to distilled water extract. Both of these two extracts have good ultraviolet light-stable and heat-stable benefits.
More studies are needed to determine what ingredients in Chaenomeles support its antimicrobial activity.
