Differences in pharmacokinetics and ex vivo antioxidant activity following intravenous and oral administrations of emodin to rats.

abstract：:Using two UV-spectrophotometric methods, the hydrolysis of tinidazole was studied at pH 1.00-8.45 at 80 degrees C. The reaction followed apparent first-order kinetics throughout the studied range. No kinetic salt effect was detected, indicating that at least one of the reacting partners forming the transition state ha...
