Broccoli seed extract (sulforaphane & glucoraphanin)

Probably the most significant role of broccoli is in the prevention and fight against cancer. Broccoli contains more vitamin C than cabbage, tomato and celery, especially in the treatment of gastric cancer and breast cancer.
Studies have shown that serum selenium levels in patients with gastric cancer are significantly lower. And the concentration of vitamin C in gastric juice is also significantly lower than that of normal people. Broccoli can not only supple a certain amount of selenium and vitamin C, but also supply rich carotene. Which can prevent the formation of precancerous cells and inhibit the growth of cancer.
According to research by American nutritionists, broccoli contains a variety of indole derivatives, which can reduce the level of estrogen in the human body and prevent the occurrence of breast cancer.
In addition, studies have shown that an enzyme extracted from broccoli, called sulforaphane, can prevent cancer by increasing the activity of carcinogen-detoxifying enzymes.
The broccoli seed is one of best source for making glucoraphanin and sulforaphane.

Sulforaphane & Glucoraphanin

Sulforaphane is an isothiocyanate, which is obtained by the hydrolysis of glucosinolate (Glu for short) by myrosinase enzyme in plants. The molecular formula is C6H11NOS2. It is rich in cruciferous plants such as broccoli, kale, and northern round carrot. It is a common antioxidant and is the plant active substance with the best anti-cancer effect found in vegetables.


Glucoraphanin, a precursor of sulforaphane with natural anticancer properties, is found in high amounts in cruciferous vegetables, especially broccoli seeds or sprouts.


The effect of sulforaphane is very powerful, but the product with high content is very unstable, and it is very easy to destroy when the temperature is not controlled well. Glucoraphanin, a precursor of sulforaphane with natural anticancer properties, exhibits very good stability.  Glucoraphanin is converted into sulforaphane through the action of intestinal flora and myrosinase enzyme, which will be absorbed by the human body.
