In order to evaluate edible safety of Yellow Ezi and improve its comprehensive utilization, this study determined respectively the content of gardenia yellow pigment and Heavy Metals in Yellow Ezi. By digestion of the yellow Ezi light, the content of minerals and gardenia yellow pigment were deter-mined by UV spectrophotometry. The results showed that the content of minerals and gardenia yellow pig-ment in Yellow Ezi was rich. Arsenic as the object of study, the experimental study was carried out to e-valuate the acute oral toxicity, rat, micronucleus, sperm deformity of bone marrow cells of rat in 180 days feeding safety toxicology. The results showed that in the determination of the 40 batch of Yellow Ezi sam-ples, arsenic, mercury compounds, cadmium content were dissolved in water:w ( arsenic) ≤0. 061 3 ug/g, w (mercury) ≤0. 015 3 ug/g, w (CD) ≤0. 016 7 ug/g, which were extremely small. Genetic toxicity tests showed no significant correlation, 180 days feeding test results showed that, under the ex-perimental dose range, there were non-toxic side effects. The results show that the content of gardenia yellow pigment in Yellow Ezi is rich, which has good food safety. 4tabs. ,8refs.%为评价黄枙子的食用安全性,以提高黄枙子的综合开发利用,本研究对黄枙子中枙子黄色素和重金属的含量分别进行了测量.将黄枙子光波消煮,用紫外分光光度计测定其矿物质和枙子黄色素的含量,测试结果显示黄枙子中的矿物质和枙子黄色素含量丰富.本研究以砷为研究对象,进行急性经口毒性、大鼠精子畸形、大鼠骨髓细胞微核、180天喂养等安全性毒理学评价试验研究.试验结果表明：所测定的40批黄枙子样品中,其水溶出物中的砷、汞、镉含量分别为：w(汞)≤0.0153 ug/g、w(砷)≤0.0613 ug/g,w(镉)≤0.0167 ug/g,均极其微小；遗传毒性试验结果无显著相关性,180天喂养试验结果表明,在本试验剂量范围内无毒副作用.研究结果显示：黄枙子中的枙子黄色素含量丰富,且具有较好的食用安全性.表4,参8.
