摘要
水煮醇沉法从中药板蓝根中提取板蓝根多糖,以其为试验药物,观察在Marc-145单层细胞上对猪繁殖与呼吸综合征病毒(PRRSV)的作用效果。结果表明,在安全浓度范围内,板蓝根多糖体外对PRRSV具有较好的阻断和抑制作用,其最小阻断浓度为2.094μg/mL,最小抑制浓度为8.375μg/mL。
In this experiment, Isatis root polysaccharide（IRPS） was extracted from isatis root by water-extraction and ethanol-precipitation and was added into Marc-145 cells before or after with porcine reproductive and respiratory syndromes virus （PRRSV） respectively to evaluate its effect on the virus infection. The results showed that. in the safe concentration scope, IRPS has a good blocking and inhibitory action to PRRSV in vitro, the minimum concentration of blocking is 2. 094μg/mL, and the minimum inhibitory concentration is 8. 375μg/mL.
