avenacoside/エンバク

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

Sterols from both green and etiolated oat plants (Avena sativa) contain sitosterol, stigmasterol, cholesterol, Δ(7)-stigmastenol, Δ(7)-cholestenol and campesterol. In the saponin fraction avenacosides A and B and 26-desgluco-avenacosides A and B were detected. Etiolated plants incorporated [4-(14)C]

Sensory-directed fractionation of extracts prepared from oat flour (Avena sativa L.) followed by LC-TOF-MS, LC-MS/MS, and 1D/2D-NMR experiments revealed avenanthramides and saponins as the key phytochemicals contributing to the typical astringent and bitter off-taste of oat. Besides avenacosides A

A total of 59 taste active molecules were quantitated, and then rated for their individual taste impact on the basis of dose-over-threshold factors (DoT) in oat flour (Avena sativa L.). A sensitive HPLC-MS/MS-method was developed to quantitate bitter-tasting steroidal and furostanol-saponins as well

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

Owing to their high content of flavonoids and saponins, plantlets of Avena sativa L. (Poaceae) are likely to possess anti-inflammatory and immunoregulatory properties of value in the treatment of atopic dermatitis (AD). With a view to its potential use in atopic subjects at risk of developing
