WASHINGTON (Reuters) - The top Republican in the Congress on Wednesday denounced President Barack Obama's new rule on contraceptives as an assault on religious freedom and vowed to overturn it, as the White House sought to prevent the issue from becoming an election-year liability.

Abstract
A sensitive and simple HPLC method was developed for the simultaneous quantification of berberine and lysergol in rat plasma. The chromatographic separation was achieved on a C(18) column using isocratic elution with methanol-acetonitrile-0.1% ortho-phosphoric acid (25:20:55, v/v/v), pH adjusted to 6.5 with triethylamine and detected at a UV wavelength of 230 nm. The extraction of the berberine and lysergol from the rat plasma with methylene chloride resulted in their high recoveries (82.62 and 90.17%). HPLC calibration curves for both berberine and lysergol based on the extracts from the rat plasma were linear over a broad concentration range of 50-1000 ng/mL. The limit of quantification was 50 ng/mL. Intra- and ...div id=medwormpbiMedWorm Message:/i/b Find the best a href=http://www.januarysales.org/ target=_blankJanuary Sales/a in the UK./p/div
