Abstract:
Proso millet (Panicum miliaceum) is neglected in human nutrition. Thanks to the composition of the grains, millet is suitable for people with celiac disease and it is also useful in the prevention of cardiovascular diseases. For screening the substances in all plant parts of millet via GC-MS, two varieties, Hanacká Mana and Unicum, were used. Substances from the group saccharides, amino acids, fatty acids, carboxylic acids, phytosterols and others were identified in the roots, leaves, stems, and seeds. The highest level of saccharides was found in the stems (83%); amino acids in the roots (6.9%); fatty acids in the seeds (24.6%); carboxylic acids in the roots (3%), phytosterols in the seeds (10.51%); other substances, such as tetramethyl-2-hexadecenol (1.84%) and tocopherols (2.15%), in the leaves; retinal in the roots (1.30%) and squalene in the seeds (1.29%). Saccharides were the dominant group in all plant parts of proso millet followed by fatty acids. The dominant saccharides in all parts of the millet plant were sucrose, fructose and psicose. On the contrary, turanose, trehalose, glucose and cellobiose belonged to the least represented sugars. Additionally, amyrin, miliacin, campesterol, stigmasterol, β-sitosterol, and others were identified. Varietal variability can be assumed, e.g., in retinal, miliacin or amyrin content.
摘要:
Proso小米(Panicummiliaceum)在人类营养中被忽略。由于谷物的组成,小米适合患有乳糜泻的人,也可用于预防心血管疾病。为了通过GC-MS筛选小米所有植物部分中的物质,两个品种,HanackáMana和Unicum,被使用。来自糖类的物质,氨基酸,脂肪酸,羧酸,植物甾醇和其他在根中被发现,叶子,茎,和种子。在茎中发现了最高水平的糖(83%);根中的氨基酸(6.9%);种子中的脂肪酸(24.6%);根中的羧酸(3%),种子中的植物甾醇(10.51%);其他物质,如四甲基-2-十六烯醇(1.84%)和生育酚(2.15%),在叶子中;根中的视网膜(1.30%)和种子中的角鲨烯(1.29%)。在谷子的所有植物部分中,糖类是优势基团,其次是脂肪酸。谷子植株各部位的优势糖类均为蔗糖,果糖和阿洛酮糖。相反,松二糖,海藻糖,葡萄糖和纤维二糖属于代表最少的糖。此外,amyrin,米利辛,菜油甾醇,豆甾醇,β-谷甾醇,和其他人被确认。可以假设品种变异性,例如,在视网膜,米利辛或苦参素含量。
