A reverse phase HPLC method to determine piperine, a pungent constituent of black pepper, in rabbit serum and various tissues of the rat was developed. A pharmacokinetic study was performed in rabbits and tissue distribution studies were carried out in rats. High reproducibility was achieved in quantitative analysis over the concentration range of 0.2-20 micrograms/ml serum. After bolus intravenous administration of piperine at a dose of 10 mg/kg, the serum concentration--time curve fitted the two-compartment open model. The tissue distribution pattern of piperine in rats also supports the two-compartment open model.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D014018 Tissue Distribution Accumulation of a drug or chemical substance in various organs (including those not relevant to its pharmacologic or therapeutic action). This distribution depends on the blood flow or perfusion rate of the organ, the ability of the drug to penetrate organ membranes, tissue specificity, protein binding. The distribution is usually expressed as tissue to plasma ratios. Distribution, Tissue,Distributions, Tissue,Tissue Distributions
