- 摘要:
- 以茯苓为试材,采用分光光度法测定茯苓多糖和三萜类化合物含量,并以此作为其品质的定量评价指标,研究了传统发汗切制和趁鲜切制2种初加工方法对其品质的影响。结果表明:茯苓多糖在10~100 μg线性关系良好(R2=0.9992),趁鲜切制与发汗切制的茯苓饮片多糖平均含量分别为87.77%和91.44%,方差分析显示F=15.30>F0.01;三萜类成分在10~70 μg线性关系良好(R2=0.9999),趁鲜切制与发汗切制的茯苓饮片三萜类成分平均含量分别为2.318‰和2.334‰,方差分析显示F=0.1880<F0.05。表明茯苓采用不同初加工方法对多糖含量有极显著影响,发汗切制法高于趁鲜切制法,对三萜类成分无显著影响。
- Abstract:
- Taking Poria as test material,using spectrophotometry to determin the content of polysaccharide and riterpenes,and as these indexes to evaluate the quality of Poria,the effect of fresh cutting and sweating cutting methods on the quality were studied.The results showed that Poria polysaccharides in 10~100 μg had good linear relationship (R2=0.9992),the polysaccharides average content of Poria which processed by fresh cutting and sweating cutting were respectively 87.77% and 91.44%.Variance analysis showed F=15.30>F0.01;Poria triterpenes in 10~70 μg had good linear relationship (R2=0.9999),the triterpenes average content of Poria which processed by fresh cutting and sweating cutting were respectively 2.318‰ and 2.334‰.Variance analysis showed F=0.1880<F0.05.Above results indicated that Poria prepared by initial processing methods had significant effect on the polysaccharides content,by sweating cutting method was higher than by fresh cutting method,and it had no significant effect on triterpenes of Poria.
