  • Patent number: 6682697
    Abstract: The present invention relates generally to the sterilization and disinfection of agricultural and botanical products such as botanical powders. More particularly, the present invention is directed towards the use of HBS technology whereby contaminated agricultural products are contacted, at ambient pressure, with an oxidant such as nascent oxygen or hydroxyl radicals thus resulting in the oxidization and destruction of the contaminating microorganisms.

  • Patent number: 6428824
    Abstract: 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.
