建立巴戟天多糖、还原糖含量的测定方法,优选巴戟天最佳盐蒸工艺。方法:采用苯酚-硫酸法测定巴戟天中多糖含量,采用3,5-二硝基水杨酸(DNS)法测定巴戟天中还原糖含量,并进行方法学考察;以盐蒸巴戟天色泽、质、味等方面的性状评分和多糖、还原糖及总糖含量为指标,采用拉丁方试验优选巴戟天盐蒸工艺,通过GraphPad Prism 5.0软件分析工艺参数。结果:苯酚-硫酸法测定巴戟天多糖精密度、重复性、稳定性的RSD分别为0.69%、3.00%、2.39%,加样回收率为98.39%。DNS法测定巴戟天还原糖精密度、重复性、稳定性的RSD分别为0.35%、3.10%、2.85%,加样回收率为98.85%。拉丁方试验优选巴戟天盐蒸工艺最佳加盐量、闷润时间、蒸制时间分别为3、4、9 h。巴戟天盐蒸后多糖、还原糖及总糖含量均有增加。结论:通过苯酚-硫酸法、DNS法测定巴戟天中多糖及还原糖含量,获得了最佳的巴戟天盐蒸工艺参数。 |

Abstract: |
Objective: To investigate the methods for determining the content of polysaccharides and reducing sugar in Morinda officinalis,and to optimize the salt-water steaming process of Morinda officinalis.Methods: The phenol-sulfuric acid method was used to measure the content of polysaccharides in Morinda officinalis,and the 3,5-dinitrosalicylic acid (DNS) method was used to measure the content of reducing sugar in Morinda officinalis; a methodological investigation was also performed.With the indicators of the scores of properties (color,texture,and taste) and the content of polysaccharides,reducing sugar,and total sugar in Morinda officinalis after salt-water steaming,the Latin square experiment was used to optimize the salt-water steaming process of Morinda officinalis,and GraphPad Prism 5.0 was used to analyze process parameters.Results: For the phenol-sulfuric acid method for measuring polysaccharides in Morinda officinalis,the relative standard deviations of precision,reproducibility,and stability were 0.69%,3.00%,and 2.39%,respectively,with a recovery rate of 98.39%.For the DNS method for measuring reducing sugar in Morinda officinalis,the relative standard deviations of precision,reproducibility,and stability were 0.35%,3.10%,and 2.85%,respectively,with a recovery rate of 98.85%.The Latin square experiment showed that the optimal durations of salt treatment,covered moistening,and steaming were 3 hours,4 hours,and 9 hours,respectively.There were increases in the content of polysaccharides,reducing sugar,and total sugar in Morinda officinalis after salt-water steaming.Conclusion: The optimal salt-water steaming process of Morinda officinalis was obtained by measuring the content of polysaccharides and reducing sugar using the phenol-sulfuric acid method and the DNS method. |
