| Use | Broccoli extract is an active ingredient extracted from Brassica cruciferous broccoli. It contains protein, sugar, fat, vitamins, carotene and other nutrients. In addition, it also contains isothiocyanate, flavonoids (Flavonoids), volatile oil and other pharmacological components. Broccoli extract can prevent breast cancer, rectal cancer and gastric cancer and other cancers, and also has a strong ability to remove DPPH free radicals; ascorbic acid can enhance the detoxification ability of the liver and improve the body's immunity. The flavonoids contained in it have the function of regulating and preventing hypertension and heart disease. |
The nutritional ingredients of broccoli are very comprehensive. The main ingredients are protein, carbohydrates, minerals, fat, dietary fiber, carbohydrates, carotene, vitamin A, vitamin C, vitamin E, calcium, etc., especially broccoli The protein content is twice that of cabbage flowers, vitamin A is 240 times and 6 times that of cabbage flowers and tomatoes, and the calcium content is twice that of tomatoes.
Anticancer effect
An enzyme called radish extracted from broccoli has the effect of increasing the detoxifying enzyme activity of carcinogens, thereby preventing the occurrence of cancer. The most important anti-cancer active ingredient in broccoli extract is isothiocyanate, which has high biological activity and can induce apoptosis of human liver cancer cells and gastric adenocarcinoma SGC-7901 cells.
Antioxidation
Broccoli extract has a strong ability to scavenge DPPH free radicals, indicating that broccoli contains antioxidant substances that can scavenge hydroxyl free radicals, alkyl free radicals or peroxy free radicals, and can block lipid peroxygen chain reaction, and the ability to scavenge DPPH free radicals is positively correlated with the amount of broccoli extract. The DPPH free radical scavenging ability of broccoli water-soluble extract is stronger than that of fat-soluble extract, which indicates that broccoli contains a variety of antioxidant substances with different polarities.
Other effects
Broccoli is also rich in anti-blood acid, so eating more broccoli can not only prevent cancer, but also enhance the detoxification ability of the liver and improve immunity. The high fiber can effectively reduce the absorption of glucose in the stomach, lower blood sugar, and effectively control the condition of diabetes.

Extraction process of broccoli polysaccharide
Broccoli & rarr; Drying and crushing & rarr; Degreasing and depigmentation & rarr; Ultrasonic extraction & rarr; Extraction and slag removal & rarr; Decompression concentration & rarr; Alcohol precipitation & rarr; Drying & rarr; Crude polysaccharide
Weigh 100g broccoli, dry it in a drying oven to constant weight, crush it and pass through an 80-mesh sieve. Degreasing with petroleum ether according to the solid-liquid ratio of 1:3, removing monosaccharides, oligosaccharides and pigments with 80% ethanol, and repeatedly operating for 3 times. After drying at 65 ℃, different solid-liquid ratios, extraction time and ultrasonic power were designed for ultrasonic extraction, and the extract was centrifuged at 4000r /min for 10min. Then use a rotary evaporator to concentrate under reduced pressure, dialyze for 24 hours, add 95% ethanol to the dialysate, make the ethanol concentration 80%, stand overnight, filter, wash the solid with absolute ethanol, petroleum ether, acetone, and dry After obtaining broccoli refined polysaccharide.
originated in Europe, broccoli can be regarded as a high-end vegetable with complete nutrients, rich in protein, carbohydrates, fats and a variety of vitamins. it mainly eats green buds and stems, with good flavor and high nutritional value, so it is loved by consumers. In addition, broccoli also contains many antioxidants, such as flavonoids and polyphenols, which can effectively prevent lung cancer, intestinal cancer and other diseases, so it is known as the "vegetable crown".
