## Abstract

Processes for producing an extract containing phytochemicals from pomegranates are disclosed. The processes generally comprise providing pomegranate solids, such as the pericarp, inner membrane and seeds; creating a mixture comprising the pomegranate solids in an aqueous solution; adding enzymes to the mixture in an amount sufficient to at least partially degrade the pomegranate solids; heating the mixture to a temperature that permits the maximum rate of catalysis of the enzyme; maintaining the temperature of the heated mixture for a time sufficient to allow at least partial degradation of the pomegranate solids; and removing residual insoluble solid materials from the mixture. Compositions containing the extract may be used as a food product, beverage, pharmaceutical preparations, nutritional supplements, vitamin supplements, food additives, and food supplements. The composition may also be used for preventing or ameliorating disease conditions by administering an effective amount of the composition to a subject in need thereof.

## Claims

### Claim 1

A method of modulating growth and progression of cancerous cells, the method comprising:
selecting a subject having cancerous cell growth;
administering to said subject a composition comprising an effective amount of a pomegranate extract, whereby said pomegranate extract is produced by a process comprising:
providing one or more pomegranate solids selected from the group consisting of a pericarp, inner membrane and seeds;
creating a mixture comprising said one or more pomegranate solids in an aqueous solution;
adding hydrolyzing enzymes to said mixture in an amount sufficient to at least partially degrade said one or more pomegranate solids;
heating said mixture to a temperature that permits enzyme catalysis of said pomegranate solids;
maintaining said mixture at a temperature and time sufficient to allow at least partial degradation of the pomegranate solids;
and removing residual insoluble solid materials from said mixture to provide an extract, wherein said extract contains polyphenols.

### Claim 2

A method of modulating growth and progression of cancerous cells comprising:
selecting a subject having cancerous cell growth;
administering to said subject a composition comprising an effective amount of a pomegranate extract and pomegranate juice, whereby said pomegranate extract is produced by a process comprising:
providing one or more pomegranate solids;
creating a mixture comprising said one or more pomegranate solids in an aqueous solution;
adding hydrolyzing enzymes to said mixture in an amount sufficient to at least partially degrade said one or more pomegranate solids;
heating said mixture to a temperature that permits enzyme catalysis of said pomegranate solids;
maintaining said mixture at a temperature and time sufficient to allow at least partial degradation of said one or more pomegranate solids;
and removing residual insoluble solid materials from said mixture to provide an extract, wherein said extract contains polyphenols.

### Claim 3 (depends on 2)

The method of claim 2 wherein said pomegranate solid is selected from the group consisting of pericarp, inner membrane and seeds from a pomegranate fruit.

### Claim 4 (depends on 3)

The method of claim 3 wherein said pomegranate solid comprises the remainder of a whole pomegranate fruit following extraction of substantially all liquid from arils of said whole pomegranate fruit.

### Claim 5

A method of increasing Prostate Specific Antigen doubling time in a subject having prostate cancer comprising:
selecting a subject having prostate cancer;
administering to said subject a composition comprising an effective amount of a pomegranate extract, whereby said pomegranate extract is produced by a process comprising:
obtaining one or more pomegranate solids;
creating a mixture comprising said one or more pomegranate solids in an aqueous solution;
adding hydrolyzing enzymes to said mixture in an amount sufficient to at least partially degrade said one or more pomegranate solids;
heating said mixture to a temperature that permits enzyme catalysis of said one or more pomegranate solids;
maintaining said mixture at a temperature and time sufficient to allow at least partial degradation of said one or more pomegranate solids;
and removing residual insoluble solid materials from said mixture to provide an extract, wherein said extract contains polyphenols.

### Claim 6 (depends on 5)

The method of claim 5 wherein said pomegranate solid is selected from the group consisting of pericarp, inner membrane and seeds from a pomegranate fruit.

### Claim 7 (depends on 5)

The method of claim 5 wherein said pomegranate solid comprises the remainder of a whole pomegranate fruit following extraction of substantially all liquid from arils of said whole pomegranate fruit.

### Claim 8

A method of increasing Prostate Specific Antigen doubling time in a subject having prostate cancer, the method comprising:
selecting a subject having prostate cancer;
administering to said subject a composition comprising an effective amount of a pomegranate extract and pomegranate juice, whereby said pomegranate extract is produced by a process comprising of
providing one or more pomegranate solids;
creating a mixture comprising said one or more pomegranate solids in an aqueous solution;
adding hydrolyzing enzymes to said mixture in an amount sufficient to at least partially degrade said pomegranate solids;
heating said mixture to a temperature that permits enzyme catalysis of said one or more pomegranate solids;
maintaining said mixture at a temperature and time sufficient to allow at least partial degradation of said one or more pomegranate solids;
and removing residual insoluble solid materials from said mixture to provide an extract, wherein said extract contains polyphenols.

### Claim 9 (depends on 8)

The method of claim 8 wherein said pomegranate solid is selected from the group consisting of pericarp, inner membrane and seeds from a pomegranate fruit.

### Claim 10 (depends on 8)

The method of claim 8 wherein said pomegranate solid comprises the remainder of a whole pomegranate fruit following extraction of substantially all liquid from arils of said whole pomegranate fruit.
