摘　　要：目的比较分析不同产地辣椒叶中钙、铁、锌元素含量。方法采用电感耦合等离子体-原子发射光谱法(ICP-AES)测定产地为四川、甘肃、山东、湖南和广东的共14份辣椒叶样品中钙、铁、锌元素的含量。结果辣椒叶平均钙含量超过28 mg/g,铁含量高达0.4 mg/g,锌含量达49μg/g。结论辣椒叶中钙、铁含量丰富,食用价值高。Objective To compare and analyze the content of Ca, Fe, Zn in Capsicum annuum leaves from different origin. Methods The inductively coupled plasma-atomic emission spectrometry （ICP-AES） was used to determine the content of calcium, iron and zinc in the Capsicum annuum leaves, and the total of 20 samples come from Sichuan, Gansu, Shandong, Hunan and Guangdong. Results The average calcium content in Capsicum annuum leaves was more than 28 mg/g, the content of iron was up to 0.4 mg/g, the zinc content was 49 μg/g. Conclusion Capsicum annuum leaves are the best source of calcium and iron.
