The antibacterial activity of compounds obtained from licorice was measured against upper airway respiratory tract bacteria such as Streptococcus pyogenes, Haemophilus influenzae and Moraxella catarrhalis. Among the tested compounds, licoricidin exhibited the highest activity against all tested microorganisms with an MIC of 12.5 microg/mL. Three coumarin derivatives, glycyrol, glycyrin and glycycoumarin also showed antibacterial activity.
测定了从甘草中提取的化合物对诸如化脓性链球菌、流感嗜血杆菌和卡他莫拉菌等上呼吸道细菌的抗菌活性。在测试的化合物中，licoricidin对所有测试微生物表现出最高活性，其最低抑菌浓度（MIC）为12.5微克/毫升。三种香豆素衍生物，即甘草醇、甘草灵和甘草香豆素也显示出抗菌活性。
