摘　　要：豆茶决明〔Cassia nomame（Sieb.）Kitag.〕为云实科（Caesalpiniaceae）决明属（Cassia Linn.）一年生草本植物[1],其地上部分及种子可入药,主治水肿、肾炎、慢性便秘、咳嗽和痰多等,并具有驱虫、健胃之功效,也可代茶饮用[2],在药理和保健方面具有多重功效,是极具开发潜力的野生植物资源。Morphological characteristics,main nutrient composition and part of mineral element contents in seeds of Cassia nomame（ Sieb.） Kitag. from five populations in Yanshan Mountains were analyzed. The results show that length,width and thickness of seeds from different populations of C. nomame are 3. 36- 3. 50 mm,2. 46- 2. 61 mm and 1. 18-1. 28 mm,respectively. Hundred-grain mass is 0. 86-1. 13 g,water content is 4. 82%- 5. 28%. The contents of soluble sugar,soluble protein and crude fat are 29. 98- 49. 79 mg · g-1,21. 52- 24. 03 mg·g-1and 30. 08- 55. 58 mg · g-1,respectively. The contents of Fe,Mn,Cu,Zn,Ca and Mg is 49. 39- 67. 35 μg·g-1,10. 50-14. 15 μg·g-1,10. 61-13. 63 μg·g-1,42. 22- 52. 82 μg·g-1,6. 78- 9. 42 mg·g-1and 4. 87- 5. 37 mg·g-1,respectively. In general,there is no significant difference in length,width,water content and soluble protein content in seeds from different populations,while there is significant difference in thickness,hundred-grain mass,soluble sugar content,crude fat content and mineral element（ including Fe,Mn,Cu,Zn,Ca and Mg） contents in seeds.
