Streszczenie

W ostatnich latach bioaktywne hydrożele oparte na naturalnych źródłach roślinnych, są często przedmiotem badań w biotechnologii i farmacji. W tej pracy dokonano przeglądu badań strukturalnych i konformacyjnych wybranych bioaktywnych hydrożeli, izolowanych z następujących ziół: morszczyn Fucus vesiculosus L., żywokost Symphytum officinale, macierzanka Thymus pulegioides, kozieradka Trigonella foenum-graecum L., podbiał Tussilago farfara L., hyzop Hyssopus officinalis, prawoślaz Althaea officinalis L., siemię lniane Linum usitatissimum L. i skrzyp Equisetum arvense L., różnicując je na żele nieoczyszczone i oczyszczone. Hydrożele zbudowane są z trójwymiarowej sieci polimerów polisacharydowych. Jedną z najważniejszych właściwości hydrożeli alginianowych jest zdolność do absorpcji, uwalniania i retencji związków chemicznych, w tym głównie wody. Widma FTIR pokazują obszary zmian w zakresie wiązań wodorowych 3500–3100 cm–1, charakterystyczne dla wiązań wodorowych (intermolekularnych i intramolekularnych).

Abstract

In recent years, some bioactive hydrogels isolated from natural sources have attracted much attention in the field of biochemistry and pharmacology. This article attempts to review the current structural and conformational characterization of some importantly bioactive hydrogels isolated from following plant: Symphytum officinale, Thymus pulegioides, Trigonella foenum-graecum L., Tussilago farfara L., Hyssopus officinalis, Althaea officinalis L., Equisetum arvense L. Linum usitatissimum L. and Fucus vesiculosus L. Hydrogels are cross-linked three-dimensional polysaccharide macromolecular networks that contain a large fraction of water within their structure. FT-IR spectroscopic analysis showed a strong band at 3500–3100 cm–1 attributed to hydroxyl (the intermolecular and the intramolecular hydrogen bonds) stretching vibrations changes.
