Содержание химических элементов и биологически активных веществ в листьях подорожника большого ( Plantago major L. ) в условиях антропогенно нарушенных местообитаний

Abstract

Проведено исследование элементного химического состава листьев, водных и водно-спиртовых извлечений P. major, произрастающего в антропогенно нарушенных местообитаниях. Достоверных отличий между валовым содержанием химических элементов (ХЭ) в исследуемых и аптечных образцах не обнаружено, сырье соответствует требованиям СанПиН 2.3.2.1078-01. Степень извлечения ХЭ 10% HCl максимальна для K, Na, Ni (86-98% от валового содержания), минимальна для Cu (33-68) и Pb (21-76). В водные извлечения в значительной степени переходят K (57±3% от валового содержания), Na (41±3), Mg (38±4), Sr (33±2), a также Cd (69±9) и Ni (42±5), низкой степенью извлечения характеризуются Cu (5±1), Pb (6±0,2), Fe (0,4±0,01). В водно-спиртовые экстракты переходило значительно больше Pb (54±13 % от валового содержания), примерно те же количества Сu, Na и Ni, прочие ХЭ извлекались слабее. Содержание полисахаридов соответствует требованиям Государственной фармакопеи (не менее12%), количество дубильных веществ составляет 5,5-6,9%, флавонолов - 0,22-1,05%, хлорофилла - 4,0-13,5%

A study of the elemental chemical composition of leaves, water and hydro-alcoholic extracts of P. major, growing in anthropogenically disturbed habitats. Significant differences between the total content of chemical elements (ChE) in the studied samples and pharmacy are found, the raw material complies Sanitary 2.3.2.1078-01. The recovery rate of 10% HCl ChE maximum for K, Na, Ni (86-98% of total content), the minimum for Cu (33-68) and Pb (21-76). In the aqueous extract largely transferred K (57±3% of the total contents), Na (41±3), Mg (38±4), Sr (33±2), a well as Cd (69 ± 9) and Ni (42 ± 5), characterized by a low degree of extraction of Cu (5±1), Pb (6.0±0.2), Fe (0.4±0.01). In aqueous-alcoholic extracts passed significantly more Pb (54±13% of the total content), about the same amount of Cu, Na, and Ni, other ChE extracted weaker. Polysaccharide content complies with the State Pharmacopoeia (not less than 12%), the amount of tannins is 5.5-6.9%, flavonols 0.22-1.05%, chlorophyll 4.0-13.5%
