Methane production from in vitro rumen incubations with Lotus pedunculatus and Medicago sativa, and effects of extractable condensed tannin fractions on methanogenesis
Inhibitory effects of condensed tannins on methane, hydrogen, total gas and volatile fatty acid formation were explored for the forage legumes Lotus pedunculatus and Medicago sativa and increased accumulated hydrogen for all treatments. Expand
Effect of flavan-3-ols on in vitro egg hatching, larval development and viability of infective larvae of Trichostrongylus colubriformis.
Comparisons were made between the flavan-3-ols and their galloyl derivatives with the in vitro effects of CT extracts from several forage legumes, which have exhibited effects on parasites in vivo. Expand
Isolation and characterization of the lignans, isolariciresinol and pinoresinol, in flaxseed meal.
This is the first report of isolariciresinol and pinoresinol being detected in a food, and the lignan trimethylsilyl ether derivatives were characterized by gas chromatography/mass spectrometry. Expand
Assessment of data on the lignan content of foods.
The plant lignans, secoisolariciresinol (SEC) and matairesinol (MAT) are converted to the metabolites, enterodiol (ED) and enterolactone (EL), known as the mammalian lignans in the gastrointestinalExpand
Variation of Proanthocyanidins in Lotus Species
A wide variation was found in the chemical composition, mean degree of polymerization (mDP), and polydispersity of PAs from Lotus spp. Expand
Green tea flavan-3-ols and oligomeric proanthocyanidins inhibit the motility of infective larvae of Teladorsagia circumcincta and Trichostrongylus colubriformis in vitro.
Fractions containing epigallocatechin gallate (EGCG) and proanthocyanidin oligomers were most effective and GTE fractions were more effective against T. circumcincta than T. colubriformis larvae as assessed by the LMI assay. Expand
Characterization of condensed tannins from Lotus species by thiolytic degradation and electrospray mass spectrometry
Abstract The properties of condensed tannins (CT) from Lotus corniculatus and L. pedunculatus (also known as L. uliginosus ) depend on their structure in terms of monomer units, their mean degree ofExpand
Variation in antimicrobial action of proanthocyanidins from Dorycnium rectum against rumen bacteria.
The results suggest the effects of the extractable proanthocyanidins on rumen microbes should be considered when evaluating an alternative proanthOCyanidin-containing forage source for ruminants, such as D. rectum. Expand
In vivo anthelmintic activity of Dorycnium rectum and grape seed extract against Ostertagia (Teladorsagia) circumcincta and Trichostrongylus colubriformis in sheep
The results indicate that the in vivo anthelmintic activity of these CT sources is, at best, modest and is unlikely to be of any practical value, and emphasise that in vitro activity is an unreliable indicator of in vivo efficacy for CT-containing forages and extracts. Expand
Hepatogenous photosensitization of ruminants by Brachiaria decumbens and panicum dichotomiflorum in the absence of sporidesmin: lithogenic saponins may be responsible.
Samples of Brachiaria decumbens and Panicum dichotomiflorum on which cattle and goats had recently been photosensitized were analyzed and the level of saponins associated with these photosensitization outbreaks were determined by GC-MS. Expand
