Abstract

Enzyme-linked immunosorbent assay (ELISA) systems using anti-ginsenoside Rb1 (G-Rb1) and Rg1 (G-Rg1) monoclonal antibodies (MAbs) were established for pharmacokinetic investigations of G-Rb1 and G-Rg1 in rat serum. The systems not only allowed sensitive detection of G-Rb1 at the level as low as 20 ng/ml and of G-Rg1 at 300 ng/ml, but showed strong capacity for detecting the two agents in a broad concentration range (20 to 400 ng/ml for G-Rb1 and 0.3 to 10 μg/ml for G-Rg1, respectively). In this respect, these assay systems are superior to other methods using thin-layer chromatography (TLC) or high-performance liquid chromatography (HPLC). In addition, another advantage of these immunoassays is the comparably low quantities of specimen required; as little as 5 μl of serum suffices the need for determination of ginsenosides. We report in this article the application of this immunoassay in pharmacokinetic study of G-Rb1.
