Optimization of Extraction of Antibacterial Compounds from Red Ants with Response Surface Methodology

doi:10.7506/spkx1002-6630-201422014

Abstract

Abstract:

Antibacterial compounds were extracted from wild red ants from the Changbai Mountains and their antibacterial
activity was evaluated. The anti-E. coli activity as a function of ethanol concentration, solid-to-solvent ratio and centrifugal
speed was investigated using response surface methodology. The diameter of the inhibition zone against E. coli was 2.59 cm
under the optimal extraction conditions: 63% aqueous ethanol, a solid-to-solvent ratio of 1:26 (g/mL) and centrifugation at a
speed of 7 230 r/min.

Key words: response surface methodology, red ant, antimicrobial compounds
