A competitive enzyme-linked immunosorbent assay (ELISA) for saikosaponins was established using monoclonal antibody (MAb) 3G10. Hybridoma 3G10 prepared by fusing splenocytes immunized with saikosaponin a-BSA (SSa-BSA) conjugate and a hypoxanthine-aminopterin-thymidine (HAT)-sensitive mouse myeloma cell line, P3-X63-Ag8-U1, secreted monoclonal antibodies with wide cross-reactivity to saikosaponins including saikosaponin b2 (SSb2), c (SSc) and d (SSd), which are stereo and/or regio isomers of SSa. The method, at an effective measuring range of 0.6 μg /ml to 2.3 μg/ml of SSa, successfully detected total saikosaponins in Bupleuri radix and Kampo medicines prescribed with Bupleuri radix. Good correlation between ELISA and HPLC analyses of total saikosaponin in a crude extract of Bupleuri radix was obtained after hydrolysis of acyl saikosaponins by treatment with a mild alkaline solution.
