摘要

除了研究植物中的生物活性有机化合物外,确定生长在环境不利地区的植物中元素的生物学作用也越来越重要。俄罗斯的一个这样的地区是库兹巴斯,其集中发展的化学,冶金和煤炭开采部门。本研究对库兹巴斯地区红三叶草(Trifolium pratense L.)、alsike clover (Trifolium hybridum L.)和白三叶草(Trifolium repens L.)自然居群的植物材料进行了评价。 采用伏安法测定了三叶草样品中重金属的定性和定量组成。用光比色法测定了钼和磷的含量。用凯氏定氮法测定总氮和蛋白质。用分光光度法定量镍、钴和铬。 我们对三叶草样品的植物材料进行重金属分析,发现红三叶草中铅的含量最少,alsike三叶草中铅的含量最高。铜的变化范围更大,红三叶草中铜的变化最小,而白三叶草中铜的变化最小。锌在白三叶草和红三叶草中的含量高于在苜蓿中的含量。所有三叶草样品中的镉含量都超过了最大允许浓度。我们还发现三叶草样品含有不同数量的各种氨基酸,包括精氨酸、缬氨酸、赖氨酸、甘氨酸、天冬氨酸和丙氨酸。 库兹巴斯地区生长的三叶草植物材料可用于改善土壤肥力和氮素状况。然而,由于高浓度的镉,三叶草不应用于农场动物的散装饲料。

A phytochemical study of the clover growing in Kuzbass
In addition to studying bioactive organic compounds in plants, it is increasingly important to determine the biological role of elements in plants growing in environmentally unfavorable areas. One of such regions in Russia is Kuzbass with its intensively developing chemical, metallurgical, and coal mining sectors. In this study, we assessed the plant materials of red clover (Trifolium pratense L.), alsike clover (Trifolium hybridum L.), and white clover (Trifolium repens L.) collected from their natural populations in Kuzbass. The qualitative and quantitative composition of heavy metals in the clover samples was determined voltammetrically. The contents of molybdenum and phosphorus were measured by the photocolorimetric method. Total nitrogen and protein were determined by the Kjeldahl method. Nickel, cobalt, and chromium were quantified by spectrophotometry. We analyzed the plant materials of the clover samples for heavy metals and found that the content of lead was the least in red clover and the highest in alsike clover. Copper varied in a larger range and was minimal in red clover compared to that in alsike and white clover. Zinc was found at higher concentrations of in white and red clover compared to that in alsike clover. The levels of cadmium exceeded the maximum permissible concentrations in all the clover samples. We also revealed that the clover samples contained different amounts of various amino acids, including arginine, valine, lysine, glycine, aspartic acid, and alanine. The plant materials of the clover species growing in Kuzbass can be used to improve the fertility of soil and nitrogen regime. However, the clover species should not be used in bulk feed for farm animals because of high concentrations of cadmium.

期刊介绍: The journal «Foods and Raw Materials» is published from 2013. It is published in the English and German languages with periodicity of two volumes a year. The main concern of the journal «Foods and Raw Materials» is informing the scientific community on the works by the researchers from Russia and the CIS, strengthening the world position of the science they represent, showing the results of perspective scientific researches in the food industry and related branches. The main tasks of the Journal consist the publication of scientific research results and theoretical and experimental studies, carried out in the Russian and foreign organizations, as well as on the authors'' personal initiative; bringing together different categories of researchers, university and scientific intelligentsia; to create and maintain a common space of scientific communication, bridging the gap between the publications of regional, federal and international level.
