摘要:为明确九头狮子草的抗菌有效组分及其化学成分,采用大孔树脂柱层析将药材的乙醇提取物进行分段,依次用水、80%乙醇、丙酮溶液洗脱,获得3个不同极性的组分A、B、C;采用纸片扩散法对各个组分进行抗菌活性评价,筛选出九头狮子草的抗菌有效组分,并用试管稀释法测定有效组分的最低抑菌浓度(MIC)及最低杀菌浓度(MBC);应用气相色谱-质谱(GC-MS)联用技术对筛选出的有效组分中的成分进行定性、定量分析。结果表明:九头狮子草各组分均有不同程度的抗菌作用,其中大孔树脂柱层析丙酮洗脱部位(即组分C)抗菌活性最强,从该有效组分中鉴定出26种成分,均为脂肪酸及其衍生物。因此脂肪酸及其衍生物是九头狮子草中的主要抗菌有效成分。
To determine the antibacterially effective fraction from Peristrophe japonica (Thunb.) Brem. and to clarify its chemical components. The ethanol extract of Peristropke japonica (Thunb.) Brem. was separaled by macroporous resin column chromatography eiuted with water, 80% ethanol and acetone, respectively, to give the fractions A-C. The in vitro antibacterial effects of the fractions were determined by the disc diffusion test. The anti-bacterial potencies of the active fraction was then assessed in vitro by determi- ning the MICs and MBCs. The chemical structures and relative con- tents of the components present in the antibacterially effective fraction were determined by gas chromatography mass spectrometry (GC MS). Each fraction from Peristrophe japonica (Thunb.) Brem showed different levels of antibacterial activity with fraction C (the acetone fraction) being the most active fraction. Twenty six com- pounds were identified by GC-MS in the effective fraction, these compounds are fatty acid and its derivatives. The fatty acid and its derivatives is the main antibacterially active ingredients in Peristrophe japonica.
