Abstract

The need for a systematic phytochemical studying of Nepeta cataria L. is related to solving the problem of using of this valuable plant resource. The purpose of the work was to study the dynamics of the accumulation of biologically active substances in the aboveground phytomass of N. cataria L. in the Republic of North Ossetia-Alania. In years 2008-2013 the study of N. cataria L. was carried out in a culture on the basis of standard methods. The aboveground phytomass of N. cataria L. contains a variety of biologically active substances. A study of the dynamics of the content of the main biologically active substances in ontogenesis showed that during mass flowering, the maximum content is reached for essential oils, total acidity, ascorbic acid, and the content of tannins. The content of individual biologically active substances did not depend on the ontogenesis phase and remained at the same level during the growing season. There was established the relationship between the biologically active substances content and the weather and climate conditions of the year: direct – with average air temperature and inversely proportional – to the amount of precipitation. Keywords— Nepeta cataria L., phenological phases of development, biologically active substances, antibacterial activity
猫薄荷(Nepeta Cataria L.)地上生物量生物活性物质含量的研究
为了解决这一宝贵植物资源的合理利用问题,有必要对其进行系统的植物化学研究。本研究旨在研究北奥塞梯-阿拉尼亚共和国卡塔利亚(N. cataria L.)地上生物量中生物活性物质积累的动态。2008-2013年,在标准方法的基础上,在培养物中对假丝莲进行了研究。卡塔利亚属植物的地上生物量含有多种生物活性物质。对个体发生过程中主要生物活性物质含量的动态研究表明,在大量开花期间,精油、总酸度、抗坏血酸和单宁含量达到最大值。个体生物活性物质的含量不依赖于个体发生阶段,在生长季节保持相同的水平。已经确定了生物活性物质含量与一年的天气和气候条件之间的关系:与平均气温成正比,与降水量成反比。关键词:荆芥,物候发育阶段,生物活性物质,抗菌活性
