title: [FT-IR spectroscopic analysis in monitoring of hydroxyl stretching vibrations in plant hydrogels].
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.
