Plants of the genus , including fragrant agrimony Wallr., mainly used as pharmaceutical raw material, perfectly fit into the current trends in nutrition and food technology that are searching for organic raw materials with high contents of bioactive compounds, such as dietary polyphenols and fiber. The aim of the research was to determine the nutritional and polyphenolic composition of fragrant agrimony Wallr. from experimental cultivation with varying levels of nitrogen fertilization in the nitrate, ammonium, or amide forms. In the experimental cultivation of fragrant agrimony in a seeding medium with a moderately high level of mineral content, the aerial parts, especially the leaves, were characterized by contents protein, dietary fiber, fat, and polyphenols at levels of 11.5, 58.0, 3.0, and 10.5% of dry matter, respectively, and an energy value of about 260 kcal/100 g of dry matter. The effect of additional nitrogen fertilization, in the form of ammonium nitrate and urea, on the content and yield of nutrients and polyphenol in fragrant agrimony depends both on the dose and the form of nitrogen, as well as the morphological part, of the plant.
该属植物，包括香苦荬菜（Wallr.），主要用作药用原料，完全符合当前营养和食品技术的趋势，即寻找具有高含量生物活性化合物（如膳食多酚和纤维）的有机原料。本研究的目的是确定不同氮施肥水平（硝酸盐、铵盐或酰胺形式）下实验栽培的香苦荬菜的营养成分和多酚组成。在中等矿物质含量的播种培养基中进行香苦荬菜的实验栽培，地上部分，特别是叶子，分别以干物质的 11.5%、58.0%、3.0%和 10.5%的水平，具有蛋白质、膳食纤维、脂肪和多酚的含量，以及约 260 千卡/100 克干物质的能量值。以硝酸铵和尿素形式的额外氮施肥对香苦荬菜的营养成分和多酚含量和产量的影响，既取决于氮的剂量和形式，也取决于植物的形态部分。
