Chaparral's resin also contains other promising chemicals, such as flavones, which have also been shown to exert anticancer effects. Four of the chaparral flavones demonstrated potent antiviral activity (7). Fluid extracts of this Western bush have also been shown to have germicidal activity against five different kinds of bacteria (8). Side Effects: Contact with the resins of the creosote bush can cause an allergic skin reaction called "contact dermatitis" (9). Taken internally, NDGA's ability to harm the kidneys has also been known for years.

One system breaks bioflavonoids into isoflavones, anthocyanins, flavans, flavonols, flavones, and flavanones.1 Some of the best-known bioflavonoids, such as genistein in soy (p. 332) and quercetin (p. 328) in onions, can be considered subcategories of the categories. Although they are all structurally related, their functions are different. While they are not considered essential, some bioflavonoids do support health as anti-inflammatory, antihistaminic, and antiviral agents.

Flavonoids with unsaturated rings, such as flavones, are defined by stereoisomerism. Biosynthetic Origin In this classification scheme, one group of flavonoids includes those that are both intermediate steps in biosynthesis and end products, such as chalcones and flavanones. The other flavonoids constitute a second group in that they are known only as end products. These include anthocyanins and flavonols. Molecular Size This scheme differentiates among monomeric, dimeric, trimeric, and polmeric flavonoid structures.

In some breast cancers, for example, the aromatase enzyme is responsible for causing androgens to convert to estrogen. flavones, such as those found in Chinese skullcap, and isoflavones, like those found in red clover and soy products, interrupt that process and actually redirect androgens for ultimate elimination rather than conversion into estrogen. In prostate cancer, the importance of androgens to fuel the cancer is significant; at least 75 percent of all tumors in men with metastatic prostate cancer are androgen-dependent at initial diagnosis.

Cyclization can then occur to give a pyranone ring containing flavanone nucleus, which can either have the C2-C3 bond oxidized (unsaturated) to give the flavones or be hydroxylated at position C3 of the pyranone ring to give the flavanol group of flavonoids. The flavanols may then be further oxidized to yield the anthocyanins, which contribute to the brilliant blues of flowers and the dark colour of red wine.

The most common flavonoids are called flavonols, flavones, and isoflavones. Large studies prove that people who regularly eat foods rich in flavonoids are much less likely to develop heart disease or have a stroke than those who avoid such foods. Also, the flavonoids in green tea have shown an amazing ability to reduce the risk of cancer. Organosulfur compounds. Garlic, the best-known food containing these, makes your immune system stronger, destroys germs, and keeps cancer-causing substances from forming. Isothiocyanates are a type of organosulfur compound found in cruciferous vegetables.

While there are numerous structural classes within the flavonoids, the most commonly occurring are flavones (e.g. apigenin) and flavonols (e.g. quercetin). Role in plant physiology Flavonoids are universal within the plant kingdom—they are the most common plant pigments next to chlorophyll and carotenoids. They are recognised as the pigments responsible for autumnal leaf colours as well as for the many shades of yellow, orange and red in flowers.

Wogonin also suppresses production of hepatitis B virus surface antigen. The flavones interact with the benzodiazepine-binding site of the GABAA receptor, with wogonin and baicalein being the most potent; this supports the sedative use of the herb. Baicalein is antigenotoxic in vitro and inhibits adhesion molecule expression induced by thrombin and cell proliferation of OH-Y\ OH O Baicalin several types of cells. Wogonin inhibits nitric oxide production in activated C6 rat glial cells, acting via NF-kB inhibition and thus suppressing cell death.

Almost 600 'chemopreventive' agents are known; they are usually classified as: inhibitors of carcinogen formation (ascorbic acid, tocopherols, phenols), inhibitors of initiation (phenols, flavones) and inhibitors of postinitiation events ((3-carotene, retinoids, terpenes). Many are items of food or beverages (e.g. tea) and are sometimes called 'functional foods' or 'nutraceuticals'. Those that are used purely as foods are not covered here, but some others can be found in the chapters for which they are most useful (e.g. ginger, Chapter 13; garlic, Chapter 14).

When fresh, the mature plant contains protoanemonine (an acrid and vesicant substance), saponins, flavones and reportedly an alkaloid (jervine) and a glucoside (helleborin). But while very young, its content in irritating principles is s ) low that it can be eaten raw; often it is a ided to salads in moderate quantities. Lat sr, it needs to be boiled in several cha iges of water. The plant loses its acridity on drying, as t le protoanemonine is transformed into anc monine, a nonirritating substance.
