The main source of polyphenols is dietary, since they are found in a wide array of phytochemical-bearing foods.For example, honey; most legumes; fruits such as apples, blackberries, blueberries, cantaloupe, pomegranate, cherries, cranberries, grapes, pears, plums, raspberries, aronia berries, and strawberries (berries in general have high polyphenol content [5]) and vegetables such as broccoli ...
Natural phenols are a class of molecules found in abundance in plants. Many common foods contain rich sources of polyphenols which have antioxidant properties only in test tube studies. As interpreted by the Linus Pauling Institute, dietary polyphenols have little or no direct antioxidant food value following digestion. [7]
Others, such as some polyphenols and flavonoids, may be pro-oxidants in high ingested amounts. [23] Non-digestible dietary fibers from plant foods, often considered as a phytochemical, [24] are now generally regarded as a nutrient group having approved health claims for reducing the risk of some types of cancer [25] and coronary heart disease. [26]
Hence, many larger polyphenols are biosynthesized in situ from smaller polyphenols to non-hydrolyzable tannins and remain undiscovered in the plant matrix. Most polyphenols contain repeating phenolic moieties of pyrocatechol, resorcinol, pyrogallol, and phloroglucinol connected by esters (hydrolyzable tannins) or more stable C-C bonds ...
Sun-dried tomatoes boast the highest concentration of lycopene among tomato products, with 45.9 milligrams of lycopene per 100 grams. A 130-gram serving of fresh tomatoes contains 4 to 10 milligrams.
Each ¼ cup (1 ounce) of pumpkin seeds provides about 2.4 mg of iron, about 15% of the daily recommendation, plus a boost of magnesium, phosphorus, potassium and zinc.
C 6-C 7-C 6 Diarylheptanoids are not included in this Harborne classification.. They can also be classified on the basis of their number of phenol groups. They can therefore be called simple phenols or monophenols, with only one phenolic group, or di-(bi-), tri-and oligophenols, with two, three or several phenolic groups respectively.
