The antiparasitic activity of avenacosides against intestinal nematodes.

Veterinary Parasitology, 2017
Avena sativa L., 1753 (Poaceae) is used as feed for livestock and as a crop rotation agent. The purpose of the study was to examine the molecular mechanisms behind the antihelminth activity of the oat saponins avenacoside B (AveB) and 26-desglucoavenacoside B (26DGAveB) by evaluating their effect on Heligmosomoides bakeri, a parasitic nematode of mice.

Avenacosides: Metabolism, and potential use as exposure biomarkers of oat intake

Molecular Nutrition & Food Research, 2017
ScopeExposure biomarkers used for objective estimation of whole‐grain (WG) intake are essential for epidemiologic studies of WG consumption, however, up to now, no exposure biomarkers were developed for WG oat intake. This study investigates the potential of oat unique components, Avenacoside‐B (AVE‐B) and –A (AVE‐A), as exposure biomarkers of oat ...

Rapid analysis of avenacosides in grain and husks of oats by UPLC-TQ-MS.

Food Chemistry, 2013
Avenacosides A (AA) and B (AB) as well as 26-desglucoavenacoside A (26dAA) were quantified in oats using rapid and sensitive method utilising UPLC-TQ-MS. In the grain, AA and AB were revealed as the primary saponins, whereas in the husks, dAA was predominant.

Revised structures of avenacosides A and B and a new sulfated saponin from Avena sativa L.

Magnetic Resonance in Chemistry, 2012
The revised structures of avenacosides A and B and a new sulfated steroidal saponin isolated from grains of Avena sativa L. were elucidated. Their structures and complete NMR assignments are based on 1D and 2D NMR studies and identified as nuatigenin 3‐O‐{α‐l‐rhamnopyranosyl‐(1→2)‐[β‐D‐glucopyranosyl‐(1→4)]‐β‐d‐glucopyranoside}‐26‐O‐β‐d‐glucopyranoside

Prolamellar body and saponins: Avenacosides are not constituents of Avena etioplasts

Plant Cell Reports, 1983
Etiolated Avena leaf cells were homogenized, then fractionated into four fractions in the presence of salts by differential centrifugation, and intact etioplasts were prepared by Percoll or sucrose density gradient centrifugation. Using thin layer chromatography steroidal saponins, avenacoside A and B were found in the leaf cells and heavy cell ...
