摘要:

目的:研究酸浆宿萼总皂苷的体外抑菌效果。方法:以大肠埃希氏菌、鼠伤寒沙门氏菌、福氏志贺氏菌、单核细胞增生李斯特菌为受试菌,以抑菌圈直径、最小抑菌质量浓度(MIC)和最小杀菌质量浓度(MBC)为检验指标,研究酸浆宿萼皂苷的体外抑菌活性。结果:酸浆宿萼总皂苷对4种受试菌都有较强的抑菌效果,MIC值在2.5~20mg/mL之间;MBC值在5~20mg/mL之间;酸浆宿萼总皂苷对鼠伤寒沙门氏菌的抑菌能力大于山梨酸钾;对福氏志贺氏菌的抑菌能力与苯甲酸钠相当。结论:酸浆宿萼总皂苷对食品腐败细菌具有较明显的抑制作用。

Abstract:

The antimicrobial effect of total saponins from Physalis alkekengi Calyx against Escherichia coli, Salmonella
typhimurium, Shigella flexneri and Listeria monocytogenes was evaluated through measuring antimicrobial diameter,
minimal inhibitory concentration (MIC) and minimum bactericidal concentration (MBC). The results showed that total
saponins from P. akekengi had a strong inhibitory effect against four tested bacteria with MIC of 2.5 to 20 mg/mL and MBC
of 5 to 20 mg/mL. The antimicrobial activity of the total saponins against S. typhimurium was stronger than potassium
sorbate, and the same antimicrobial activity against Shigella flexneri was observed as sodium benzoate.

Key words: Physalis alkekengi Calyx, saponins, antimicrobial effect
