Shin’iseihaito (Xinyiqingfeitang) Suppresses the Biofilm Formation of Streptococcus pneumoniae In Vitro

Figure 5

The inhibitory effects of the extracts of each component of Shin’iseihaito on the biofilm formation of S. pneumoniae. S. pneumoniae was treated with or without each extract of the components of Shin’iseihaito and SSHT (500 µg/mL) for 2 days, and its anti-antibiofilm activity was quantified by crystal violet adsorption by measuring the absorbance at 570 nm. Data shown represent the mean ± SD (). . SSHT: Shin’iseihaito extract; AA: the rhizome of Anemarrhena asphodeloides; CH: the rhizome of Cimicifuga heracleifolia; EJ: the leaf of Eriobotrya japonica; GF: Gypsum fibrosum; GJ: the fruit of Gardenia jasminoides; LL: the bulb of Lilium lancifolium; MS: the flower of Magnolia salicifolia; OJ: the tuber of Ophiopogon japonicus; SB: the root of Scutellaria baicalensis.
