Quality control
Microscopy is less useful in quality control here, so phytochemical methods are predominant.
In the case of the crude drug, TLC is only feasible for the flavonoids. The terpene lactones are only present in a small concentration and they are accompanied by substances which interfere with the analysis. The special extracts can be analysed using the following TLC methods:
• Flavonoids: ethyl acetate/formic acid/glacial acetic acid/water (100:11:11:26), detection with diphenylboryloxyethylamine.
• Biflavones: chloroform/acetone/formic acid (75:16.5:8.5 |

The value of integrating ethnobotanical with phytochemical and pharmacological studies has been clearly demonstrated. While, for example, the likelihood of developing new therapeutic agents for use in biomedicine is relatively low (although it is certainly much higher than with many other approaches), such studies confirm the therapeutic value and contribute to our general scientific knowledge about medicinal plants (Heinrich 2003).
Some plants have many side effects or are highly toxic. |

Most beans also possess isoflavones, a phytochemical that blocks the entry of estrogen into the cell, which might slow the progress of hormone-dependent cancers like breast cancer and cancer of the cervix, depending upon a woman's estrogen status. The use of isoflavones in the treatment of hormone-dependent cancers is controversial, since isoflavones have a slight estrogenic ability. There is concern that they may fuel such cancers. There are ongoing studies being conducted to evaluate their effects. |

Both spices contain curcumin, a phytochemical renown for its antioxidant and anti-inflammatory powers. It may even work as well as ibuprofen and other NSAIDs, according to recent research.
To try curcumin's healing powers, add fresh ginger to your next stir-fry or brew some ginger tea. And getting turmeric is as easy as ordering curry at your local Indian restaurant.
If you have gallbladder trouble or take NSAIDs or blood thinning medication, like warfarin, talk with your doctor before treating your gout with these spices. |

Phytochemical screening found that alkaloids, flavonoids, and saponins were absent. Some antibiotic activity was also demonstrated. The seed extract of L. watsoni has hemagglutin activity, inactivated by heat. If this change due to heating is true also of the bark (although no such test has been reported), chewed bark may be more effective than boiled.

Peaches
What could be more welcome than the first peach of summer? Fresh peaches are fair sources of beta-carotene and good sources of ascorbic acid and fiber. A cup of sliced peaches provides one-tenth of the daily requirement of vitamin A and fiber. Yellow peaches are probably richer sources of beta-carotene than the white variety.

Bias from the established scientific research community is another reason phytochemical research has faltered. For many years, traditional researchers avoided any type of science that was related to nutrition. "Serious scientists have stayed away from the field because it gets tied up with all the supplementation people and the anti-aging crowd," said Dr. Barry Halliwell of the University of California at Davis. Dr. H. Leon Bradlow, who has been studying the link between breast cancer and hormones since 1957, expressed a similar sentiment. "Like Rodney Dangerfield, I got no respect. |
After analyzing the components of tomatoes, they concluded that lycopene, a phytochemical that is a member of the carotene family, which has potent antioxidant capabilities, might offer an answer to the question "How can we prevent prostate cancer?"
The body of knowledge continues to expand. In Vidalia, Georgia, home of Vidalia onions, it was noticed that stomach-cancer rates are half the national average. Then, this information was connected to data from an ecological study done through a cooperative effort of scientists from Cornell University Medical School and the Chinese government. |

92. Is it true that a poison such as sulfur dioxide is used on grapes?
You are confusing the colorless gas sulfur dioxide with the chemical that is used on foods as a bleaching agent or preservative. It is mildly toxic to humans when inhaled as a gas, but after being used on grapes to prevent darkening, it dissipates and is harmless to the consumer. |

Little phytochemical study has been conducted on species in the Aristolochia genus despite frequent use in various parts of the world. A series of alkaloidal acids (e.g., aristolochic acid I) has been reported from a variety of species. The root of A. brevipes was found to be highly active against Bacillus subtilis (Encarnacion and Keer 1991). No other studies of the Aristolochia species of the American and Mexican West were located. Norman Farnsworth (i993a:36D) has stated that "no herbal medicine in the genus Aristolochia should ever be used by humans over an extended period of time. |

The main immunomodulating phytochemical is plumbagin and its analog.16
Together plumbagin and its analog (hydroplumbagin) provide a variety of pharmacological properties, including antitumor, antibacterial, antiviral, and antiprotozoal activities.
A primary mechanism of action of the digestive juices produced by the Venus flytrap is the inhibition of protein-kinases. Tumor cells require protein-kinases (enzymes) to synthesize proteins. By blocking protein-kinases, the cancer cells are inhibited and die. |

According to napralert, phytochemical screening has revealed the presence of alkaloids. Like other Malvaceae, Sphaerakea has emollient properties, and its root may be used to substitute for Althea officinalis L.

MCP is a phytochemical product manufactured by modifying the carbohydrate chain length of commercial citrus pectin, the type used in jellies and jams.
To date, preliminary studies have demonstrated that MCP can inhibit the spread of prostate cancer in laboratory animals. An Italian research team established specifications and standards for clinically effective MCP. The cancer-stopping power of MCP seems to depend on whether it can be absorbed by the digestive tract into the bloodstream. It is within the bloodstream that the binding action on the migrating cancer cells takes place. |

Lycopene is a type of phytochemical, an anti-disease compound in food. It is also found in red grapefruit.
Robert Rountree, M.D., cofounder of the Helios Health Center in Boulder, Colorado, "prescribes" a teaspoon a day of tomato paste for his patients with prostate cancer. "Lycopene has more potent antioxidant properties than beta-carotene, and it has anti-cancer properties," he says. |

The uncertainties can be lessened by choosing phytochemical classes of marker compounds (flavonoids, essential oil, oligomeric pro-cyanidins, etc.) rather than just individual chemical constituents. In addition, testing for different marker compounds (or groups of marker compounds) in the one plant can lead to a better assessment of activity. However, none of this should occur at the expense of the chemical totality of the plant's extractable material. |

Fiber found in plant foods is a phytochemical. Dietary fiber is found in vegetables, fruits, legumes, nuts, seeds, and grains.
The type of fiber found in whole grains is mostly insoluble, which means that it does not break down in water. It is also indigestible, so it adds bulk to the digestive contents, speeding up the movement of food through the digestive tract. It provides relief from constipation and di-verticulosis and may help to reduce the risk of colon cancer. The role that insoluble fiber plays in disease prevention is well documented. |
