BACKGROUND Tannins are often cited for antinutritional effects, including chelation of non-heme iron. Despite this, studies exploring non-heme iron bioavailability inhibition with long-term consumption have reported mixed results. Salivary proline-rich proteins (PRPs) may mediate tannin-antinutritional effects on non-heme iron bioavailability. AIM To review evidence regarding biochemical bind...

International Scholarly Research Notices has retracted the article titled “Growth Responses and Leaf Antioxidant Metabolism of Grass Pea (Lathyrus sativus L.) Genotypes under Salinity Stress” [1]. The article was found to contain images with signs of duplication andmanipulation in Figures 5(a), 5(b), 6(a), and 6(b), and duplication from Talukdar D. Plant Growth and Leaf Antioxidant Metabolism o...

The performance of hybrids depends upon the inheritance and expression of resistance traits. Secondary chemicals are one such resistance trait. In this study, we measured the concentrations of phenolic glycosides and condensed tannins in parental and F1 hybrid willows to examine the sources of chemical variation among hybrids. S. sericea produces phenolic glycosides, salicortin and 2'-cinnamoyl...

Case 1 Thirty one years old male that presented at age 15 allergic rhinoconjunctivitis and cutaneous pruritus after ingestion of honey and spices. Three years later, he had the same symptoms with ingestion of pepper. Skin prick tests were positive to grass, mugwort, dandelion and ragweed pollen, as well as pepper, curry, paprika and anise. Serum specific IgE was positive to carrot, pea, white b...

Mammalian neurolathyrism is a progressive and degenerative disease of central nervous system originating from excessive consumption of Lafhyrus seeds, particularly those of L. sativus. Rao et al. [I] have isolated P-N-oxalyl-L-a&diaminopropionic acid (ODAP) from the seeds of L. satiuus and shown this substance to be the neurotoxin [ 1, 21 Characterization of the biochemical effect and cellular ...

The purpose of the current work was to designate effect maturity stages potential nutritive value, chemical composition, condensed tannin (CT), gas production (GP), methane production, metabolizable energy (ME), and organic matter digestibility (OMD) Rheum ribes L. Maturity significantly affected (P<0.05) CT, GP, ME OMD Dry (DM), crude ash (CA), protein (CP), ether extract (EE), neutral ...

Antiviral activity has been demonstrated for different tannin-rich plant extracts. Since tannins of different classes and molecular weights are often found together in plant extracts and may differ in their antiviral activity, we have compared the effect against influenza A virus (IAV) of Hamamelis virginiana L. bark extract, fractions enriched in tannins of different molecular weights and indi...

Although polyphenols have been reported as common constituents of propolis, tannins have rarely been mentioned as its constituents. Propolis samples from seven localities in Brazil were analyzed for detection of proanthocyanidins (condensed tannins) and determination of the tannin content. Positive reaction for proanthocyanidins was observed for all samples tested. The contents of tannins varie...
