Novel compositions extracted from corn products provide contraceptive and anti-neoplastic activities. Using novel extraction procedures, compositions may be isolated from corn products. For example, a Zea mays plant product is extracted in a first solvent to produce a solvent extract, the solvent extract is dried to produce an extracted solid, the extracted solid is solubilized in a second solvent, the solubilized extract is purified in a chromatographic process, and an active fraction is collected from the chromatographic process. Compositions may be applied to animal bedding or food, and are adaptable to any suitable method of administration. The contraceptive activity of these compositions is effective for both males and females. |
