|Title:||Characterisation of sapindosides in Sapindus mukorosii saponin (reetha saponin) and quantitative determination of sapindoside B*|
Dwivedi, A K
|Abstract:||High performance thin layer chromatography (HPTLC) method as well as high performance liquid chromatographic (HPLC) method combined with ES-MS are developed and validated for fingerprinting (profiling) Sapindus saponin and quantitative determination of Sapindoside B in bulk drug samples of Sapindus saponin and its formulation Consap cream. The separation of saponins using TLC is achieved on precoated silica gel plates using chloroform: methanol: water as mobile phase. Detection of the spots is done at the 630 nm. The identification of saponins is done by LC-MS, using Electro Spray Ionisation [ESI] technique. The HPLC method involves chromatography of the saponins on reverse phase (C-18) column, using acetonitrile-water gradient as mobile phase. The detection is done by UV -visible detector at a wavelength of 215 nm. Calibration graphs are found to be linear over the range 11-220 μg in HPTLC and 30-200 μg/mL in HPLC method. The methods developed are being used for the analysis of the bulk drug samples and Consap cream samples.|
