摘要(Abstract):

当归为常用的补血药,以阿魏酸等已知化学成分为指标难以有效评价其质量。为此,根据生物检定的原理,建立了定量测定当归药材补血活性的生物检测方法。当归药材依次用乙醇和水提取,以合并后的总提物为供试品进行小鼠补血活性试验;用环磷酰胺和盐酸苯肼联合建立小鼠血虚模型;以红细胞数为补血活性的评价指标,用环孢菌素A标定当归的补血活性。再根据量反应平行线(3·3′)法计算供试品的补血活性。结果表明,环孢菌素A和当归总提物补血活性的可靠性检验结果成立;与模型组相比,当归总提取物具有显著的补血活性(PDanggui,Agelicae Sinensis Radix,is a widely used Chinese herb to enrich blood,but its quality cannot be effectively assessed by the known chemical markers such as ferulic acid,ligustilide,polysaccharides,etc.A new bioassay was therefore developed to quantify the Enrich-Blood Bioactivity(EBB) for the quality assessment of Danggui raw materials.Danggui sample was first extracted with ethanol and water,respectively.Then the ethanolic extract and water extract were mixed as a test sample to quantify the amount of EBB by mice experiment.The blood deficiency mode in mice was developed by intraperitoneal injecting cyclophosphamide and phenylhdrazine hydrochloride.The quantity of red blood cell was chosen as EBB marker.Cyclosporine A was chosen as a control substance.EBB in analytes was quantified by the amount reaction of parallel line analysis(3,3') method.The results indicated that the reliability test for quantifying EBB was passed through and the measured value was valid.The analytes showed the significant EBB(P <0.05).The correlation coefficient was 0.998 4(n =5) between the amount of cyclosporine A(0.035-0.56 g·kg~(-1)) and the increased number of red blood cell.The relative standard deviation(RSD) on the amount of EBB was estimated to be 6.15%(n = 6)by six replicated tests,and the confidence limit rate was 26.68%(n =6).Five Danggui samples,which were collected from different cultivation areas with various morphological characters,showed the variety of EBB in the range of 21.9544.16 U·g~(-1).It is concluded that the developed method is accurate to quantify the EBB of Danggui raw materials,and is therefore suitable to assess its quality.
