Three experiments were conducted to examine the effects of vitamin E supplementation on feedlot cattle. Vitamin E supplementation did not affect feedlot performance or carcass characteristics of cattle fed a high-concentrate diet (P greater than .1). The major finding was the effectiveness of vitamin E in extending the color stability of displayed beef (P less than .01). Color stability during ...

The title compound, C(23)H(24)INOP(+)·C(24)H(20)B(-), was prepared by treatment of 3-amino-propyl triphenyl-phospho-nium bromide hydrogen bromide with p-nitro-phenyl iodo-acetate at 203 K. The asymmetric unit contains a single cation and anion, which are linked in the crystal by inter-molecular N-H⋯π and inversion-related R(2) (2)(14) C-H⋯O inter-actions, which combine to form chains of cations...

A new benzylic diglycoside was isolated from the leaves of Milicia excelsa and identified as 3,4-dimethoxybenzyl beta-D-xylopyranosyl (1 --> 2)-beta-D-glucopyranoside (1). It was obtained together with four known secondary metabolites including lupeol acetate (2), ursolic acid (3), triacontyl (E)-ferulate (4), and 2-(3,5-dihydroxyphenyl)benzofuran-5,6-diol (5). Their structures were determined ...

A new cembrane diterpene, 6-acetoxy-7,8-epoxynephthenol acetate (1) was isolated along with a known compound, epoxynephthenol acetate (2), from the organic extract of a Bornean soft coral Nephthea sp. Their structures were elucidated on the basis of spectroscopic analyses and comparison with those previous literature data.

Using potassium hexacyanoferrate (III)-sodium acetate as oxidant, the oxidative coupling reaction of isorhapontigenin and resveratrol in aqueous acetone resulted in the isolation of three new indane dimers 4, 6, and 7, together with six known stilbene dimers. Indane dimer 5 was obtained for the first time by direct transformation from isorhapontigenin. The structures and relative configurations...

A phytochemical study was conducted on the leaves of Phyllanthus reticulatus obtained from a riverside in Taman Negara Kuala Koh, Kelantan. The separations of the chemical components were carried out using different chromatographic techniques and structures of compounds were elucidated by spectroscopic methods including nuclear magnetic resonance as well as mass spectrometry. Three compounds we...

BACKGROUND Oxidative stress and inflammation are crucial in atherogenesis. alpha-Tocopherol is both an antioxidant and an antiinflammatory agent. OBJECTIVE We evaluated the effect of RRR-alpha-tocopherol supplementation on carotid atherosclerosis in patients with stable coronary artery disease (CAD) on drug therapy. DESIGN Randomized, controlled, double-blind trial compared RRR-alpha-tocoph...

This study evaluated the effect of vitamin E supplementation source, and the dose given to sows or piglets, on the fatty acid profile of colostrum, milk, subcutaneous and intramuscular fat, and the oxidative status of piglets at 39 days of age. Sows (n = 10) were given 150 mg dl-α-tocopheryl acetate/d in feed, or 75 or 50 mg micellized-d-α-tocopherol/d in water from Day 103 of pregnancy. Weanin...

Levulinyl cellulose esters have been produced as an effective renewable binder for architectural coatings. The title compound, C7H10O4 (systematic name: 2-methyl-5-oxo-tetra-hydro-furan-2-yl acetate), assigned as the esterifying species, was isolated and crystallized to confirm the structure. In the crystal, the mol-ecules pack in layers parallel to (102) utilizing weak C-H⋯O inter-actions.

The title compound, {[Cu(C(20)H(14)N(4))(2)][Cu(2)(NCS)(4)]}(n), was obtained by reacting copper acetate hydrate, ammonium thio-cyanate and 4'-(3-pyrid-yl)-2,2':6',2''-terpyridine (3-pytpy) under solvothermal conditions. The polymeric complex is isostructural with the 4'-phenyl-2,2':6',2''-terpyridine (phtpy) analogue. All intramolecular distances and angles are very similar for the two structu...
