ABSTRACT:
A soya extract having a content of glucoside isoflavones of at least 13% by weight and a content of 0.6 to 1.5 parts by weight of group 3 soya saponins per 1 part by weight of glucoside isoflavones. Also, pharmaceutical compositions containing this extract and methods of administering the extract to treat conditions such as pre- or post-menopausal symptoms, cancer, such as breast or prostate cancer, or alcoholism. The extracts are made by a process which includes the steps of treating ripe whole soya beans or oil-free soya flour with an aliphatic alcohol to obtain a first extract; concentrating the first extract to form a concentrated first extract; purifying the concentrated first extract by treatment with at least one aliphatic hydrocarbon; and extracting active components from the purified concentrated first extract with a water-immiscible aliphatic alcohol to obtain a second extract. Preferably, the final extract is concentrated dried to form the desired soya extract.
