Содержание ряда ценных биологически активных компонентов в растительном лекарственном сырье Горного Алтая

Abstract

Проведены исследования по оценке содержания ряда биологически актив-ных веществ в лекарственных растениях, произрастающих в Горном Алтае. Содержание аскорбиновой кислоты в окрашенных экстрактах исследуемого растительного сырья определяли колориметрическим методом с 2,6-дихлор-фенолиндофенолом. Определение содержания дубильных веществ в раститель-ном сырье проводили титриметрическим методом в пересчете на танин. Сумму флавоноидов в растительном сырье определяли методом дифференци-альной спектрофотометрии с AlCl3 в пересчете на рутин. Метод определения флавоноидов и дубильных веществ модифицирован в части отделения экстракта от растительного остатка, что ощутимо сокращает время пробоподготовки анализируемых проб. В результате проведенных исследований получены новые данные по содер-жанию биологически активных соединений в ряде лекарственных растений, произрастающих в природных условиях Северного и Центрального Алтая. Приве-дены данные по общему содержанию флавоноидов в аналогичных ботанических видах и семействах других регионов России. Влияние различных биоклиматиче-ских условий произрастания представителей лекарственной флоры находит отражение в широком диапазоне содержания суммы флавоноидов. Research has been carried out to estimate the content of several biologically active substances in medical plants growing in Gorny Altai. The content of ascorbic acid in the colored extracts of the medical plant material has been determined by the colorimetric method by 2,6-dichlorophenolindophenol. Determination of the content of tannins in plant raw materials has been carried out by the titrimetric method in terms of tannin. The total content of flavonoids in the medical plant material has been determined by differential spectrophotometry with AlCl3 in terms of rutin. The method for the determination of flavonoids and tannins has been modified in terms of separating the extract from the medical plant residue. This modification significantly reduces the sample preparation time for the analysis. A new data has been obtained on the content of biologically active compounds in medical plants growing in the natural conditions of the Northern and Central Altai as a result. The paper presents data on the total content of flavonoids in similar botanical species and families of other regions of Russia. The influence of different bioclimatic conditions of growth of representatives of the medical flora is reflected in a wide range of the content of the total content of flavonoids. Key words: secondary metabolites, permanganatometry, differential spectropho-tometry. This paper presents the research which has been carried out to assess the content of some biologically active substances in medical plants growing in Gorny Altai. Using standard methods of analysis, the amount of ascorbic acid and tannins in the samples under study of Northern and North-Eastern Altai was identified. The study presents the data on the total content of flavonoids in similar botanical species and families of other regions of Russia. The influence of different bioclimatic growing conditions of representatives of the medicinal flora is reflected in a wide range of the content of the sum of flavonoids.
