The invention relates to compositions that can be isolated from Lepidium plant material and to methods for their isolation. The compositions are useful for treating and preventing cancer and sexual dysfunction.

Compositions and methods for their preparation from lepidium

An isolated composition obtained by extracting roots is provided. The composition is substantially free of cellulose and comprises between about 5% and about 9% of benzyl isothiocyanate, between about 1% and about 3% of Lepidium sterol component, between about 20% and about 30% of Lepidium fatty acid component, and about 10% or more of macamide component. The composition is prepared by a process which comprises contacting Lepidium meyenii roots with a first aqueous solvent of about 90% vol-% or more water, then separating the residual root material from the first contacted aqueous solvent, then contacting the residual root material with a second aqueous solvent which comprises a mixture of an alcohol and water having about 90 vol-% alcohol or more to form a liquor, and then finally concentrating the liquor to obtain the composition. The composition can be used for treating cancer and sexual dysfunction.
