Technical Abstract: Saponins are very potent bioactive compounds found in many legumes and other plants and have been shown to exhibit health benefits such as cholesterol reduction, antioxidant activity, stress reduction, tumor suppression, and as a pain depressant. We have developed a low-cost extraction device for removing bioactive compounds from micro samples of peanut meal and soybean flour using pressure and temperature. This extraction procedure significantly reduces sample size, solvent consumption, and extraction time. Saponins were separated from the crude extracts by HPLC and characterized by Fast Atom Bombardment (FAB) mass spectrometry. Mass spectra investigation of extracted peanut samples has revealed the presence of four saponins and four saponins were extracted from soybean flour. FAB mass spectrometry provided information concerning molecular masses and aglycone composition.
