Active ingredients of HS consist of humus, humic acid (HA), fulvic acid (FA), ulmic acid, and some microelements (Senn and Kingman, 1973).
It is important to note that in previous studies in the scientific literature, the commercial products tested in broiler chickens also contained different types of HS (humic, fulvic, ulmic and humatomelanic acids) and different trace minerals (Kocabagli et al.
The chemical analysis of mud does not only reveal hydrophilic organic substances, such as humic, fulmic, and ulmic acids, but also organic substances composed of fatty acids.
Fulvic, ulmic and humic acids, all of which have been isolated from peat, have been found to be of particular importance in the biological effects of peat (Beer et al.
The influence of fulvic and ulmic acids from peat on the spontaneous contractile activity of smooth muscles.
Fourier Transform Ion Cyclotron Resonance (FT-ICR) and Matrix Assisted Laser Desorption Ionization (MALDI) mass spectrometry are used to systematically study ulmic acid extracts taken from a sediment sample in the Gulf of Mexico.
Keywords: Ulmic acid, FT-ICR, MALDI-TOF-MS, bryostatin
Ulmic acid is defined as the alcohol-based extract of naturally-occurring organic matter (NOM).
The focus of this paper is to use FT-ICR in the role of elemental analysis for molecular components of ulmic acid taken from an ecosystem in the Gulf of Mexico.
With a view to clarifying the excitatory action of aqueous peat extract (APE) on the spontaneous contractile activity (SCA) of the smooth muscles, in vitro studies were made of the influences of the water-soluble HPLC-fractions of fulvic and ulmic acids separated from peat on smooth-muscle preparations of guinea-pig stomach.
Key words: peat, smooth muscles, fulvic acids, ulmic acids, [[alpha].
The effects of APE on SCA of the smooth muscles are connected with the water-soluble components of fulvic (F) and ulmic (U) acids contained in APE.
