Title:  Method of preparing and using compositions extracted from vegetable matter for the treatment of neurological conditions

United States Patent:  6,509,381

Issued:  January 21, 2003

Inventors:  Empie; Mark (Forsyth, IL); Gugger; Eric (Latham, IL)

Assignee:  Archer Daniels Midland Company (Decatur, IL)

Appl. No.:  136158

Filed:  May 1, 2002

Abstract

A composition is prepared by extracting and isolating phytochemical fractions from plant matter for treatment for neurological conditions and especially for migraine headaches, inflammations, dementia, and Alzheimer's Disease. The composition is enriched, preferably with two or more different fractions, namely: isoflavones, lignans, saponins and saponogenins, catechins, and phenolic acids. The two selected fractions are different from each other and are combined specifically to form a composition to treat a neurological condition. Soy is the preferred source of these phytochemicals; however, other plants may also be used, such as wheat, psyllium, rice, oats, red clover, kudzu, alfalfa, flax, and cocoa. The composition may be delivered in an easy to use or consume form, such as cream, pills, tablets, capsules, pellets, dry powder, health bars, food ingredients and supplements, soft gels, and the like.

SUMMARY OF THE INVENTION

An object of this invention is to provide a convenient way for individuals to consume isoflavones, lignans, saponins, catechins and/or phenolic acids, either as a nutritional supplement or as an ingredient in a more traditional type of food.

An other object of this invention is to provide an optimized extract composition of phytochemicals which is in sufficient concentration to be delivered in an easy to consume dosasge such as a pill, tablet, capsule, liquid or ingredient in a food.

Yet another object of this invention is to prepare the phytochemical extract to be delivered as a topical application in a cream or lotion. In this form, the isoflavones, lignans, saponins, catechins and/or phenolic acids are dispersed and suspended in a suitable liquid or gel matrix to render a stable cream or lotion as the delivery vehicle.

A further object of this invention is to provide an extract concentrate which is closely similar in chemical composition to the chemical entities found in the natural plant source.

In keeping with this aspect of the invention, the isoflavones, lignans, saponins, catechins and/or phenolic acids are extracted from a suitable vegetable source to render a composition which is substantially more concentrated than the original material and by more than 5 times in one or more of the desired bioactive components.

This extract may be used alone or combined with one or more other plant extracts to produce the optimized composition. Further, this extract composition may be formulated with one or more other dietary nutrients, such as vitamins, minerals, amino acids, etc., to provide a nutritional supplement further optimized for a desired health effect. All these ingredients may be combined with necessary binders, excipients, preservatives, colors and the like known to those in the industry in order to produce a suitable tablet, capsule, pill, liquid, cream, powder or food ingredient.

These phytochemicals may be packaged and provided in final form by means known to the supplements and food ingredient industries. The materials are intended to provide health and well-being benefits.

DETAILED DESCRIPTION OF THE INVENTION

The improved composition is obtained by fractionating a plant source high in isoflavones, lignans and other phytochemicals such as defatted soybean flakes, soy molasses, soy whey, red clover, alfalfa, flax, cocoa, tea, or kudzu root. These may be fractionated along or in combination with these other plants known to be high in the various isoflavones, lignans, saponins, catechins and phenolic acids. The fractionation results in substantially removing water, carbohydrates, proteins, and lipids from the source material. The fractionation method may be preferably that disclosed in co-pending U.S. Pat. No. 5,702,752 or U.S. Pat. No. 4,428,876, or an extraction using ethyl acetate or n-butanol may be used. U.S. Pat. No. 5,702,752 is assigned to the assignee of this invention.

Other extraction processes, which may be used alone or in combination, include differential solubility, distillation, solvent extraction, adsorptive means, differential molecular filtration and precipitation.

The preferred composition is an improvement over known commercial materials regarding the amount of phytochemicals per gram of substance and the amounts of different phytochemicals present which affect physiologic function.

These natural substances have been consumed in food sources for long periods of time and more closely relate to the substances consumed which provide the basis for the epidemiological evidence for health benefits. Additional benefits may be derived from improved physical properties relative to phytochemicals chemically modified from their original food source form.

The resulting composition is expected to comprise in a preferred form: between 5% and 95% isoflavones, between 0% and 70% lignans, and between 2% and 70% saponins and sapogenins. In a more preferred form, the composition will be extracted from soy. In another preferred form, the composition will contain a ratio of (saponins plus saponogenins) to isoflavones from 1:100 to 100:1, with the isoflavones consisting predominantly of naturally occurring derivatives of genistein and/or its precursor biochanin A and daidzein and/or its precursor formononetin, with a ratio of the genistein derivatives to daidzein derivatives from 100:1 to 1:100. Preferably, the isoflavones are predominantly glycosylated derivatives.

The composition's ratios may be readily varied by changing the plant source or by combining several plant sources for extraction. Thus, as further study shows which phytochemical combinations are more efficacious for certain health effects, the particular composition will also vary.

It is known that isoflavones, lignans, and saponins can be used advantageously to treat or prevent various cancers, including breast cancer, prostate cancer, skin cancer, and colon cancer.

It is believed that the improved composition will provide increased benefits in the form of chemoprevention. Recent experiments appear to confirm this belief.

Claim 1 of 37 Claims

What is claimed is:

1. A method of treating a neurological condition selected from the group consisting of migraine headaches, inflammations, dementia and Alzheimer's Disease comprising administering to a person an amount therapeutically effective in treating said neurological condition of a composition comprising at least two fractions selected from the group consisting of isoflavones, lignans, saponins and saponogenins, catechins, and phenolic acids, said at least two phytochemical fractions being different from each other.
