Seven phenolic compounds, including a new phenylethanoid, named passifoside (1), and 6 previously described syringaresinol (2), berchemol (3), threo-guaiacylglycerol (4), p-hydroxybenzaldehyde (5), 3,4,5-trimethoxyphenyl- O- β-D-glucopyranoside (6), trans- p-coumaric acid (7), were identified from the aerial parts of Passiflora foetida. Their chemical structures elucidated HR-ESI-MS NMR spectra...

phorbiaceae. It is a shrub or small tree reaching 4—5 meters high and native to Thailand, where it is commonly called “Plao phae”. In this paper, we describe the isolation and structure elucidation of newly isolated 3 -(4 -hydroxy-3 ,5 dimethoxyphenyl)-propyl benzoate, 3 -(4 -hydroxyphenyl)propyl benzoate and four known compounds [3 -(4 -hydroxy-3 -methoxyphenyl)-propyl benzoate, poilaneic acid...

Ruminal bacteria were subjected to a series of phenolic compounds in various concentrations to acquire fundamental information on the influence on growth and the potential limits to forage utilization by phenolic monomers. Ruminococcus albus 7, Ruminococcus flavefaciens FD-1, Butyrivibrio fibrisolvens 49, and Lachnospira multiparus D-32 were tested against 1, 5, and 10 mM concentrations of sina...

It has previously been proposed that 4-methylphenol (p-cresol) is metabolically activated by oxidation of the methyl group to form a reactive quinone methide. In the present study a new metabolism pathway is elucidated in human liver microsomes. Oxidation of the aromatic ring leads to formation of 4-methyl-ortho-hydroquinone, which is further oxidized to a reactive intermediate, 4-methyl-ortho-...
