摘要： An isolated composition obtained by extracting Lepidium meyenii 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 Lepidium meyenii root material from the first contacted aqueous solvent, then contacting the residual Lepidium meyenii 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.
