摘　　要：为深入了解湖北省十堰市房县鸡头黄精(Polygonatum sibiricum Red.)生产的药用品质和食用品质,2023年10月在房县大川镇、门古寺镇、野人谷镇、化龙堰镇、上龛乡5个主要生产鸡头黄精的乡镇采收黄精肉质根状茎,测量鲜干重占比,进行鲜品切片碘染,并检测干燥品淀粉、多糖、可溶性糖和可溶性蛋白质含量。结果表明,十堰市房县鸡头黄精肉质根状茎干重占比在15.08%~28.76%,干燥根状茎淀粉含量在98.44~145.89 mg/g、多糖含量在8.59%~24.03%,均符合《中华人民共和国药典》标准,药用价值高。家种鸡头黄精的干燥根状茎可溶性糖含量在51.53~154.29 mg/g、可溶性蛋白质含量在83.18~276.21 mg/g,而野生鸡头黄精的干燥根状茎可溶性糖含量在209.93~389.40 mg/g、可溶性蛋白质含量在55.81~62.91 mg/g。In order to understand the medicinal quality and edible quality of Polygonatum sibiricum Red.in Fangxian County,Shiyan City,Hubei Province,in October 2023,the fleshy rhizoid of Polygonatum sibiricum Red.was harvested in Dachuan Town,Mengusi Town,Yerengu Town,Hualongyan Town and Shangkan Town,the fresh to dry weight ratio was measured,and the fresh slices were io⁃dine dyed.The contents of starch,polysaccharides,soluble sugar and soluble protein in dried rhizomes of Polygonatum sibiricum Red.were detected.The results showed that the dry weight proportion of the fleshy rhizomes of Polygonatum sibiricum Red.in Fang County,Shiyan City,was 15.08%~28.76%,the starch content of the dry rhizomes was 98.44~145.89 mg/g,and the polysaccharides content was 8.59%~24.03%,all of which met the standard of Pharmacopoeia of the People’s Republic of China,and the medicinal value was high.The soluble sugar content and soluble protein content of the dry rhizomes of domestic Polygonatum sibiricum Red.were 51.53~154.29 mg/g and 83.18~276.21 mg/g,respectively,while the soluble sugar content and soluble protein content of the dry rhizomes of wild Polygonatum sibiricum Red.were 209.93~389.40 mg/g and 55.81~62.91 mg/g,respectively.
