摘　　要：以牡丹Paeonia suffruticosa‘乌龙捧盛’‘白雪塔’‘迎日红’‘俊艳红’‘春红娇艳’‘万世生色’等6个品种的花瓣为材料,分析其中维生素C、粗蛋白、类黄酮、氨基酸和9种矿物元素的质量分数。结果表明:品种间类黄酮、维生素C、粗蛋白的质量分数存在较大差异,‘乌龙捧盛’中这3种营养成分质量分数均最高,分别为13.08 mg·g-1,1.12mg·g-1,0.11 g·g-1;花瓣所含氨基酸种类齐全,不同氨基酸质量分数存在差异,质量分数最高的是谷氨酸(9.64～15.83mg·g-1),最低的是半胱氨酸(0.15～0.86 mg·g-1);牡丹花瓣中富含多种矿质元素,其中微量元素硒的质量分数较高。不同品种间营养成分含量差异较大,品种‘乌龙捧盛’类黄酮、粗蛋白、维生素C、总氨基酸和钾、钙、镁、铁、铜等元素质量分数均较其他品种高,具有较高的营养价值。The vitamin C content, crude protein, flavonoids, amino acids, and nine kinds of mineral ele- ments were studied using petals of six Paeonia suffruticosa cuhivars （ ‘ Wulongpengsheng＇, ‘ Baixueta＇, ‘ Yingri- hong＇, ‘Junyanhong’,‘Chunhongjiaoyan＇ , and ‘Wanshishengse＇） as meterials. Results for ‘Wulongpeng- sheng/＇ showed a Vitamin C content of 13.08 mg·g-1, crude protein of 1.12 mg·g-~, and flavonoids of 0.11 g·g-l, which are higher than other cultivars. Meanwhile, different types of amino acids were found in sufficient quantity with the highest being glutamic acid （9.64-15.83 mg·g-1） and the lowest being cysteine （0.15-0.86 mg· g-l）. Many kinds of mineral elements were found with the microelement Se having the highest content. For nu- tritional components, great differences among different cultivars were exhibited. The synthesis analysis showed ＇Wuiongpengsheng＇ had a higiiest nutritional value, especially for flavonoids and Se. [ Ch, 3 fig. 2 tab. 14 ref.
