目的:筛选鹊肾树枝提取物中具有抗猴免疫缺陷病毒(SIV)的活性部位。方法:以SIV为靶病毒和相应的CEMx174细胞系统为模型,以3-叠氮胸苷(azidothymiding,AZT)为阳性对照药物,观察了鹊肾树枝的不同提取物对SIV的体外抑制作用;以试管法和滤纸法鉴定活性部位可能含有的化学成分。结果:鹊肾树枝的石油醚萃取物在62.5 mg.L-1时,对病毒抗原细胞抑制率为55.9%;乙酸乙酯萃取物在其浓度为15.625 mg.L-1时,对病毒抗原细胞抑制率为41.2%。石油醚萃取物可能含有挥发油、油脂和甾体或三萜类物质,而乙酸乙酯萃取物可能含有酚类物质。结论:鹊肾树枝中具有一定的抗SIV作用的成分可能为挥发油、油脂、甾体、三萜类或酚类物质。
Objective: To screen the active site of anti-Simian immunodeficiency virus (SIV) in Magpie dendrite extracts. Methods: Using SIV as target virus and corresponding CEMx174 cell system as model and azidothymidine (AZT) as positive control, the inhibitory effects of different extract of magpie dendrite on SIV were observed. Test tube and filter paper identification of the active site may contain chemical composition. Results: The inhibitory rate of the petroleum ether extract of magpie branches at 62.5 mg.L-1 was 55.9%, while that of ethyl acetate extract at 15.625 mg.L-1 of virus extracts The inhibition rate was 41.2%. Petroleum ether extracts may contain volatile oils, greases and steroids or triterpenoids, while ethyl acetate extracts may contain phenols. Conclusion: Some anti-SIV components in magpie branches may be volatile oil, oil, steroid, triterpenes or phenols.
