Five phenolic compounds, p-hydroxyacetophenone, 5,7-dihydroxychromone, naringenin, quercetin, and iso-americanol A, were found first time in the barley tea, together with the known compounds, p-hydroxybenzaldehyde, 3,4-dihydroxybenzaldehyde, p-hydroxybenzoic acid, vanillic acid, and p-coumaric acid. The anti-oxidative properties were evaluated by measuring their peroxynitrite-scavenging activities. Among these compounds, 3,4-dihydroxybenzaldehyde, p-coumaric acid, quercetin, and isoamericanol A… 
Free water-soluble phenolics profiling in barley ( Hordeum vulgare L.).
The phenolic profile of barley ( Hordeum vulgare L.) leaves, seeds, awns, and stems, collected in two different locations from Portugal, was determined by a high-performance liquid

The French Paradox at Tea Time: From Antioxidant Flavonoids and Stilbenes Toward Bio-inspired Synthetic Derivatives
Natural and synthetic xanthone derivatives are well known for their ability to act as antioxidants and/or enzyme inhibitors. This paper aims to present a successful synthetic methodology toward
Ameliorative effect of p-coumaric acid, a common dietary phenol, on adjuvant-induced arthritis in rats
The present study clearly demonstrates the anti-inflammatory potential of the p-coumaric acid against adjuvant-induced arthritis in rats.
Antioxidant Activities and Related Phytochemical Constituents of Ethanolic Extract of Some Fruits in Vitro
This work was achieved to study the antioxidant activities of ethanolic extracts of four fruits, physalis peruviana L.( pp ), Ziziphus spina-christi (z c ), Syzygium cumini (s c) and Eriobotrya
A new Erythrina alkaloid from Erythrina herbacea
The structure of the new Erythrina alkaloid, 10-hydroxy-11-oxoerysotrine, was elucidated on the basis of its spectral data, including 2-D NMR and mass (MS) spectra.
Evaluation of In vitro antioxidant properties of roasted hulled barley (Hordeum vulgare L.)
The antioxidant properties of roasted hulled barley (Hordeum vulgare L.) were tested using in vitro assays, including the total phenolic content (TPC), total flavonoid content (TFC), and DPPH, ABTS,
Antioxidant Effect of Roasted Barley (Hordeum vulgare L.) Grain Extract towards Oxidative Stress in Vitro and in Vivo
The results demonstrate potential antioxidant activities and antiaging effect of roasted barley grain and provide scientific support for the use of roast barley grain as an antioxidant against oxidative stress.


Peroxynitrite Scavenging Activities of Aromatic Compounds Isolated from Konnyaku, Amorphophallus konjac K.Koch.
Among these compounds, serotonin, trans-N-(p-coumaroyl)serotonin, 3,4-dihydroxybenzaldehyde, and 3, 4-diverseroxybenzoic acid showed stronger activities than that of BHT (butylated hydroxytoluene) at 200 μM.
Antioxidative properties of phenolic antioxidants isolated from corn steep liquor.
It was elucidated that the activity of p-coumaric acid derivatives was mainly affected by their functional groups at the 3-position and less by the conjugated side chain in CSL, and this byproduct might be a useful resource of phenolic antioxidants.
Studies on the Flavors of Roast Barley (Mugi-Cha)
Seven weakly acidic compounds were newly detected as flavor components of roast barley by using column and gas-liquid chromatographies. These compounds were characterized and identified by MS, IR, UV
Oxygenated Lycopene and Dehydrated Lutein in Tomato Puree
These compounds were isolated from tomato puree and the structures were elucidated on the basis of spectroscopic evidence.
Structures of americanol A and isoamericanol A having a neurotrophic property from the seeds of Phytolacca americana.
Isoamericanol A, americanol A, and americanin A have been found to enhance choline acetyltransferase activity at 10(-5) M in a cultured neuronal cell system derived from fetal rat hemisphere.
Structure of Isoamericanin A, a Prostaglandin I2 Inducer, Isolated from the Seeds of Phytolacca americana L.
A new neo-lignan, isoamericanin A was isolated as a prostaglandin I2 inducer from the seeds of Phytolacca americana L. and its structure was fully characterized by extensive 2D NMR and long range
Die endgültige Struktur von Americanin‐A und Hydnocarpin

Chemical composition of barley tea.
玄麦,焙煎大麦,麦茶の化学成分について検討した.(1) 焙煎処理で玄麦中のタンパク質と繊維含有割合は減少したが,エチルエーテル抽出物の割合は高くなった.焙煎大麦から得た熱水抽出物(麦茶,凍結乾燥物)中のタンパク質量は焙煎大麦中のタンパク質含有割合と同じであった.エチルエーテル抽出物と繊維の含有割合は麦茶で高く,逆に灰分とカルシウムの含有割合は麦茶で低い.(2)
