西洋参参须废渣中参多糖的提取及含量测定

Extraction and Determination of Polysaccharide from Discarded Fibrous Roots of Radix Panacis Quingueforlii

目的 :从提取西洋参皂苷后的参须废渣中进行西洋参多糖提取的可行性研究和测定。方法 :采用酶解技术和乙醇等方法脱色处理参多糖 ,用酚 -硫酸法测定活性多糖的含量 ;元素分析仪测无机元素的含量 ;原子荧光光度计测重金属的含量。结果 :参须中的西洋参多糖得率与主根中多糖的得率相近 ,以干燥品计算在1 1 .7%左右 ,并含有多种微量元素 ;重金属分析符合国家卫生标准。结论

Objective:To establish a feasible method for extracting polysaccharide from the discarded fibrous roots of Radix Panacis Quingueforlii afterpanaquilon had been extracted, and determine the polysaccharide content. Methods:Enzymolysis technique and alcohol was applied for decolorization, and phenol-sulfuric-acid method was used to determine the active polysaccharide content.The content of trace element and heavy mental was measured by element-analyzer and atomic fluorescence photometer respectively. Results: The yield of polysaccharide from the fibrous roots was close (about 11.7%) to the main root.And the content of heavy metal can match the national standard.Conclusion:It is valuable to extract the polysaccharide from the discarded fibrous root of Radix Panacis Quingueforlii.
