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 mgg－1，1.12 mgg－1，0.11 gg－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（9.64～15.83 mgg－1），最低的是半胱氨酸（0.15～0.86 mgg－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。图3表2参14Abstract: The vitamin C content，crude protein，flavonoids，amino acids，and nine kinds of mineral elements were studied using petals of six Paeonia suffruticosa cultivars （Wulongpengsheng，Baixueta，Yingrihong，Junyanhong，Chunhongjiaoyan，and Wanshishengse） as meterials. Results for Wulongpengsheng showed a vitamin C content of 13.08 mgg-1，crude protein of 1.12 mgg-1，and flavonoids of 0.11 gg-1，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 mgg-1） and the lowest being cysteine （0.15-0.86 mgg-1）. Many kinds of mineral elements were found with the microelement Se having the highest content. For nutritional components，great differences among different cultivars were exhibited. The synthesis analysis showed Wulongpengsheng had a highest nutritional value，especially for flavonoids and Se.［Ch，3 fig. 2 tab. 14 ref.］
