摘要: 为了深度开发双黄连可溶性粉(金银花、连翘、黄芩,1:1:2),并为家禽、家畜合理选择用药提供科学依据,本研究以双黄连口服液生产工艺生产的双黄连可溶性粉及其醇沉物(多糖组分)、滤液(黄酮组分)作为研究材料,以哺乳动物牦牛源轮状病毒、鸡新城疫病毒,牦牛源致病性大肠杆菌、沙门氏菌、金黄色葡萄球菌为研究对象,采用牛津杯结合平板二倍稀释法,探讨其体外抗菌活性;以牦牛MA-104细胞株、鸡胚成纤维细胞株UMNSAH/DF-1为宿主细胞,采用噻唑蓝比色法(MTT)和细胞病变(CPE)检测法,探讨其体外抗病毒活性。研究结果表明,双黄连可溶性粉对革兰氏阴性菌(牦牛源大肠杆菌、牦牛源沙门氏菌、大肠杆菌质控菌株)的抑菌效果优于对革兰氏阳性菌(牦牛源金黄色葡萄球菌、金黄色葡萄球质控菌株)的抑菌效果,从双黄连可溶性粉中分离的黄酮组分可能是双黄连可溶性粉抑菌的主要成分,而多糖组分则无抑菌活性;黄酮组分对革兰氏阳性菌的抑菌效果优于对革兰氏阴性菌的抑菌效果;双黄连可溶性粉及其黄酮组分和多糖组分对鸡胚胎成纤维细胞UMNSAH/DF-1的最小无毒浓度(TC0)分别为:2.58、1.17和1.56 μg/mL,对牦牛细胞MA-104的TC0分别为:1.290、0.585和0.780 μg/mL,对牦牛轮状病毒均具有良好的抗病毒效果,双黄连可溶性粉对鸡新城疫病毒的抗病毒效果优于黄酮和多糖组分。研究结果为双黄连可溶性粉深度开发和对畜禽合理选择用药提供了科学依据。

Abstract: In order to provide scientific basis for the in-depth development of Shuanghuanglian soluble powder(honeysuckle, forsythia, Scutellaria baicalensis, 1:1:2) and the rational selection of medicine for poultry and livestock.In this study, Shuanghuanglian soluble powder produced by production technology of Shuanghuanglian oral liquid and its alcohol precipitates (polysaccharide components) and filtrate (flavonoids components) were used as research materials.The mammals Yak source rotavirus, Newcastle disease virus, yak source pathogenic Escherichia coli, Salmonella, Staphylococcus aureus as the research object, Oxford cup combined with two-fold dilution method was used to investigate the antibacterial activity in vitro.Using yak MA-104 cell line and chicken embryo fibroblast cell line UMNSAH/DF-1 as host cells, Thiazolium blue colorimetry (MTT) and cytopathic detection (CPE) were used to investigate the antiviral activity in vitro.The results showed that the antibacterial effect of the Shuanghuanglian soluble powder on Gram-negative bacteria(Yak Escherichia coli, Yak Salmonella, Escherichia coli quality control strain) was better than that on Gram-positive bacteria (Staphylococcus aureus, Staphylococcus aureus quality control strain from yaks).The flavonoids isolated from the Shuanghuanglian soluble powder might be the main antibacterial component of the Shuanghuanglian soluble powder, while the polysaccharide component had no antibacterial activity.The antibacterial effect of soluble powder flavone components of Shuanghuanglian on Gram-positive bacteria was better than that on Gram-negative bacteria.The minimum nontoxic concentration (TC0) of Shuanghuanglian soluble powder and its flavonoids and polysaccharides on UMNSAH/DF-1 cells were 2.58, 1.17 and 1.56 μg/mL, respectively.The TC0 of MA-104 cells were 1.290, 0.585 and 0.780 μg/mL, respectively.They all had good antiviral effect for the Yak rotavirus.The antiviral effect of Shuanghuanglian soluble powder against Newcastle disease virus was better than that of flavonoids and polysaccharides components.The results provided scientific basis for the in-depth development for the Shuanghuanglian soluble powder and rational selection of medicine for livestock and poultry.

Key words: Shuanghuanglian soluble powder; flavonoid components; polysaccharide components; antibacterial activity; antiviral activity
