Abstract: The present invention concerns isoflavones and related compounds useful as antioxidants and in antioxidant compositions including edible fats and oils. Many of these compounds can be recovered from tempeh, a fermented soybean product. Others can be prepared by chemical modification of those recovered from tempeh. Additionally, all of the compounds can be chemically synthesized. The compounds of the present invention may be used to provide enhanced stability for a wide range of substances subject to oxidative deterioration including edible food products, oils and fats.

Abstract: The present invention concerns ergostadientriols which may be recovered from either the fungus R. oligosporus or the fungus R. oryzae as well as from soybeans which have been fermented with either of these fungi. Alternatively, the sterols may be chemically synthesized. The sterols of this invention are antioxidants which may be used in anti-oxidant compositions alone or preferably with one or more isoflavone. Of particular significance is the discovery that the ergostadientriols of this invention are useful in lowering serum cholesterol levels. Accordingly, this invention in a particularly preferred embodiment discloses pharmaceutical compositions containing one or more ergostadientriol. Finally, therapeutic methods which utilize pharmaceutical compositions in accordance with this invention are disclosed.

Abstract: Antioxidants and antioxidant compositions useful as stabilizers for food compositions, including edible fats and oils, and other compositions have been prepared and recovered from a natural source, tempeh, a fermented soybean product. An ergostadientriol which possesses antioxidative properties and which in combination with mixtures of isoflavones provides compositions having exceptional antioxidative properties has been produced. This new sterol, either alone or in combination with mixtures of isoflavones or other compounds, would appear to be useful in the prevention and/or treatment of various diseases including atherosclerosis. The ergostadientriol is recovered from other constituents of a methanol extract of tempeh by a separation process based upon its molecular size and adsorptive properties. Two novel isoflavones have also been produced and recovered from tempeh.
