A novel, commercially viable process for the extraction of high purity (>70%), bioactive furostanolic saponins including protodioscin (>30%), from the seeds of fenugreek (Trigonella foenumgraecum) comprising essentially the steps of powdering of the natural material followed by a first extraction, an ion-exchange chromatographic purification and a second extraction using a novel composite solvent and drying of the product under defined conditions, the entire process being carried out at essentially neutral pH and low temperatures of less than 80° C.
