摘　　要：维生素c是衡量果蔬品质的重要指标之一。为了准确评价海棠果实中维生素c的含量，本试验采用紫外分光光度法和碘量法对西府海棠和珠美海棠鲜果及干果中的维生素C含量进行了测定。结果表明：两种方法测定海棠果的维生素c含量存在差异，碘量法测得数值略高；西府海棠鲜果维生素C含量高于珠美海棠0．53～0．61mg／100g，西府海棠干果维生素c含量高于珠美海棠0．1～0．2mg／100g。此研究为海棠营养价值的进一步开发利用提供了理论指导。Vitamin C can be used as one of the important evaluation index of Malus prunifolia quality. In the experiment, fresh and dried fruits of Malus micromalus Makino and Malus zumi were used as materials, and vitamin C content were determined with spectrophotometric method and iodine quantity method. These results show that there were differences between the two methods for determining the vitamin C contents of begonia fruits, and the results measured by iodine method were higher. The vitamin C content in fresh fruits ofMalus micromalus Makino was 0.53~0.61 rag/100 g higher than that ofMalus Zumi, and the vitamin C content in dried fruits ofMalus micromalus Makino was 0.1 -0.2 mg/100 g higher than that ofMalus zumi. This study will provide a theoretical guidance for the further nutrient value develooment of the begonia.
