不同品系多花黄精药理和食用成分比较研究

目的 研究比较不同品系多花黄精的药用、营养价值差异，并进行综合评价。方法 以DH-1、DH-2、DH-3、DH-4、DH-5、DH-6 6个品系多花黄精地下部分作为实验材料，分别测量其水分、灰分、浸出物、多糖、总黄酮、总皂苷、总酚、可溶性糖、还原糖、脂肪、蛋白质、矿质元素指标，并利用隶属函数法进行综合评价。结果 多花黄精不同品系间营养价值和药用价值均存在显著差异。其中，DH-6的浸多糖含量最高，DH-3浸出物含量最高，DH-4的总黄酮、总酚和脂肪含量最高，DH-2的总皂苷和还原糖含量最高，DH-1的可溶性糖和蛋白质含量最高；6个品系均含有大量元素和微量元素。综合评价分析发现，6个品系的药用价值综合评分大小顺序依次为DH-1>DH-3>DH-4>DH-6>DH-5>DH-2，DH-1的综合评分最高；6个品系的营养指标综合评分大小顺序依次为DH-1>DH-2>DH-6>DH-4>DH-3>DH-5，DH-1的综合评分最高。结论 DH-1既适合药用也适合食用，同时也可按照相应需求对其展开进一步的开发及利用。

Comparative study on pharmacological and ediable components of different strains of Polygonatum polyflora

Objective The study compared the differences in medicinal and nutritional values of different strains of Polygonatum polyflora, and conducted a comprehensive evaluation. Methods The underground part of six strains(DH-1, DH-2, DH-3, DH-4, DH-5, DH-6) of Polygonatum polyflora were used as experiments materials. The indexes of moisture, ash, leachate, polysaccharides, total flavonoids, total saponins, total phenols, soluble sugars, reducing sugars, fats, proteins, and mineral elements were measured respectively, and the membership function method was used for comprehensive evaluation. Results There were significant differences in nutritional value and medicinal value between different strains of Polygonatum polyflora. Among them, DH-6 had the highest content of polysaccharides, DH-3 had the highest content of leachables, DH-4 had the highest content of total flavonoids, total phenols and fats, DH-2 had the highest content of total saponins and reducing sugars, and DH-1 had the highest soluble sugar and protein content; 6 strains all contained a large number of elements and trace elements. The comprehensive evaluation analysis found that the comprehensive scores of 6strains of medicinal value were DH-1>DH-3>DH-4>DH-6>DH-5>DH-2, and DH-1 had the highest comprehensive scores. The comprehensive score size of the nutritional indicators of 6 strains was DH-1>DH-2>DH-6>DH-4>DH-3>DH-5, and DH-1 had the highest comprehensive score. Conclusion DH-1 is suitable for both medicinal and consumption, and it can be further developed and utilized according to the corresponding needs.
