摘　　要：为合理采摘并有效开发荷叶资源,采用浓HNO_3-H_2O_2混合体系消解样品,制备滤液,火焰原子吸收光谱法检测滤液,探明湖北省孝感地区荷叶Ca、Fe、Zn、Cu、Pb、Cd 6种元素的含量及其在6—10月生长期的含量变化。结果表明:孝感后湖村、汉川汈汊湖和安陆赵棚镇联星村3地不同月份荷叶中Ca、Fe、Zn、Cu、和Pb元素的含量分别为4 123.56~11 861.65μg/g、70.36~150.28μg/g、22.58~39.21μg/g、54~14.57μg/g和0.38~3.54μg/g。但未检测出Cd元素。此外,荷叶的最佳采摘时间是9—10月,该时间处于荷叶生长稳定阶段,并且各种矿质元素含量相对较高。The Ca, Fe, Zn, Cu, Pb and Cd content in lotus leaves from Xiaogan area, Hubei and their content change status from June to October were detected and analyzed by FAAS to rationally harvest and effectively develop lotus leaf resources. Results： The Ca, Fe, Zn, Cu and Pb content in lotus leaves from three different lotus producing areas in Xiaogan is 4 123. 56~11 861. 65μg/g, 70. 36~150. 28μg/g, 22.58~39.21μg/g, 54~14.57μg/g and 0.38~3.54μg/g respectively but Cd is not detected in lotus leaves. The optimum harvesting time of lotus leaves is from September to October because growth of lotus leaves is at the stable stage and the content of various mineral elements in lotus leaves is relatively higher.
