| 摘要: |
| 采用水煎、水醇和五部位提取法从地锦草中提得组成成分不同的7种提取物,以肠道致病性大肠杆菌O78∶K80,沙门氏菌C79-1,金黄色葡萄球菌为目的菌株进行体外抑菌试验。结果表明,水煎提取物对大肠杆菌O78∶K80,沙门氏菌C79-1,金黄色葡萄球菌的最小抑菌质量浓度分别为10, 10, 12. 5 g /L;水醇提取物对上述试验菌的最小抑菌质量浓度依次为5, 7. 5, 10 g /L;五部位法所得5种提取物的抑菌浓度均大于15 g /L。 |

| Abstract: |
| Seven kinds of extract were obtained from Euphorbia humifusa Wild by
water decoction, water ethanol and five position methods, and were conducted
bacteriostasis test with intestine pathogenic Colon bacillus O78∶K80, Salmonella
Pullorum C79-1, staphylococcus aureus for target bacteria in vitro. The results indicated
that the minimum concentration of bacteriostasis of water decoction extract for Colon
bacillus O78∶K80,Salmonella Pullorum C79-1 staphylococcus aureus was 10, 10, 12. 5 g/L
crude drug, respectively. The minimum concentration of bacteriostasis of water ethanol
extract on abive-nebtuibed testbacteria was 5, 7. 5, 10 g/L crude drug, successively.The
concentration of bacteriostasis of five kinds of extract which obtained by five position
methodwas higher than 15 g/L crude drug. |
