亚贡用于宇航员生命支持的前景

Prospects of Yacon (Polymnia Sohchifolia Poepp. & Endl) Using for Astronauts Life Support

  • 摘要: 在长期的载人航天飞行中,生物生命维持系统是必需的,因此食物成为最重要的一种工具。植物是生物活性化合物的可获取来源。缺乏抗氧化剂会降低身体的功能活性。蔬菜类食物,包括非传统的和药用作物,是人类最主要和最经济的抗氧化剂来源。亚贡(Polymnia sonchifolia Poepp. & Endl.),是乌克兰最有前途的引种品种之一,近来开始在乌克兰作为蔬菜作物种植。这种植物的叶子中含有的高浓度的类黄酮、绿原酸、咖啡酸、硒、维生素、矿物质,使其具有很强的抗氧化性能。研究表明,亚贡块茎含糖量高,其中大部分为果糖(超过60%)。大部分果糖和糖类存在于生长在基辅地区的块茎中。在波尔塔瓦地区,叶尖中基于绿原酸的HCA含量高达4.5% DW。在基辅地区生长的植物(茎繁殖)的块根中,其含量最高(2.3%)。亚贡不同部位的生物化学成分证明,它有希望为宇航员提供多样化和健康的营养,以支持他们的长期太空任务。

     

    Abstract: During long-term manned space flights, biological life support systems are required, so food becomes an instrument of paramount importance. Plants are an accessible source of biologically active compounds. Antioxidant deficiency decreases the body's functional activity. Vegetable foods, including non-traditional and medicinal crops, are the main and most affordable source of antioxidants for humans. Yacon (Polymnia sonchifolia Poepp. & Endl.) is one of the most promising introductory species for Ukraine, and has recently started growing as a vegetable crop in our country. The leaves of this plant contain high concentrations of flavonoids, chlorogenic, coffee acids, selenium, vitamins, minerals in, which gives it strong antioxidant properties. It is shown that Yacon root tubers have a high content of sugars, most of which are fructosans (over 60%). Most of the fructosans and sugars are in root tubers grown in the Kyiv region. The amount of HCA based on chlorogenic acid is up to 4.5% DW in the tops of Yacon leaves in the Poltava region. Its content is the largest in root tubers (2.3%) of plants grown in Kyiv region (stem reproduction). The biochemical composition of different parts of Yacon has proved that it is promising for the diverse and healthy nutrition of astronauts for their life support in long-term space missions.
