High Purity Broccoli seeds Extract Sulforaphane 98%

100% Natural Broccoli /Broccoli Seeds Extract Sulforaphane 

Sulforaphane belongs to a class of compounds known as isothiocyanates. In 1992, Dr Paul Talalay of Johns Hopkins University School of Medicine and colleagues identified sulforaphane as the most potent natural inducer of phase II detoxification enzymes to date. These enzymes eliminate multiple types of free radicals and environmental pollutants, triggering sustained antioxidant effects lasting up to three days. These compounds and their mechanisms have been extensively studied, supported by over 1,700 scientific publications.

Sulforaphane (1-isothiocyanato-4-methylsulfonylbutane), also known as ‘ rapeseed isothiocyanate ’ , is an isothiocyanate with a relative molecular mass of 177.3 and the molecular formula C6H11S2NO. It is primarily produced through the hydrolysis of glucoraphanin (4-methylsulfinylbutyl thioglucoside) in Brassicaceae plants by myrosinase.

In 1992, Professor Talalay of Johns Hopkins University in the United States announced the discovery of sulforaphane's potential anti-cancer properties.

Subsequent extensive research both domestically and internationally has demonstrated that sulforaphane exhibits broad-spectrum anti-cancer effects across cells, animals, and humans, making it applicable for treating lung cancer, colon cancer, gastric cancer, breast cancer, ovarian cancer, prostate cancer, and others.

Sulforaphane functions as an Nrf2 inducer, primarily activating the Nrf2 signalling pathway to induce phase II enzyme expression while simultaneously suppressing phase I enzyme production.

Phase II enzymes block metabolic pathways required for carcinogens to exert their oncogenic effects, preventing carcinogens or their metabolites from entering target cells while also facilitating their clearance.

1.The Relationship Between Glucoraphanin and Sulforaphane

Glucoraphanin: A naturally occurring glucosinolate found in broccoli.

Sulforaphane: An isothiocyanate formed through enzymatic conversion of glucoraphanin, representing its biologically active form.

2.Biological Activity and Mechanism of Action

1. Activation of the Nrf2 Signalling Pathway:

Sulforaphane ranks among the most potent activators of Nrf2 (Nuclear Factor Erythroid 2-related Factor 2), initiating the body's cellular protection and detoxification responses.

2. Antioxidant and Anti-inflammatory Effects:

By activating Nrf2, sulforaphane promotes the production of antioxidant enzymes, combats oxidative damage, and exerts anti-inflammatory effects.

5. Anti-Cancer Effects:

Sulforaphane also induces phase II detoxification enzymes to eliminate carcinogens, thereby inhibiting cancer cell growth and metastasis to exert its anti-cancer effects.

3.Extraction Sources and Applications

1.Primary Sources:

Sulforaphane is present in cruciferous vegetables such as broccoli and cabbage, with particularly high concentrations found in broccoli seeds and sprouts.

2.Extraction Process:

Commercially, sulforaphane is primarily extracted from broccoli seeds, requiring advanced techniques including defatting, hydrolysis, and chromatographic purification.

3.Applications:

Due to its potent biological activity, sulforaphane has been developed into health products including dietary supplements and skincare formulations, enjoying widespread consumption in markets such as North America and Europe.
