Sulforaphane (sometimes sulphoraphane in British English) is a phytochemicalThe Impact of Sulforaphane on Sex-Specific Conditions and Hormone Balance: A Comprehensive Review. By: Fahey, Jed W., Raphaely, Mirran, Applied Sciences (2076-3417), 20763417, Jan2025, Vol. 15, Issue 2 within the isothiocyanate group of organosulfur compounds.{{cite web |title=Isothiocyanates |url=https://lpi.oregonstate.edu/mic/dietary-factors/phytochemicals/isothiocyanates |publisher=Micronutrient Information Center, Linus Pauling Institute, Oregon State University |access-date=21 January 2025 |date=2025}} It is produced when the enzyme myrosinase transforms glucoraphanin, a glucosinolate, into sulforaphane upon damage to the plant (such as from chewing or chopping during food preparation), which allows the two compounds to mix and react.
Sulforaphane is present in cruciferous vegetables, such as broccoli, Brussels sprouts, and cabbage.
Sulforaphane has two possible stereoisomers due to the presence of a stereogenic sulfur atom.{{cite journal | vauthors = Janczewski Ł | title = Sulforaphane and Its Bifunctional Analogs: Synthesis and Biological Activity | journal = Molecules | volume = 27 | issue = 5 | pages = 1750 | date = March 2022 | pmid = 35268851 | pmc = 8911885 | doi = 10.3390/molecules27051750 | doi-access = free }}
The R-sulforaphane enantiomer occurs naturally, while the S-sulforaphane can be synthesized.{{cite journal | vauthors = Zhang Y, Lu Q, Li N, Xu M, Miyamoto T, Liu J | title = Sulforaphane suppresses metastasis of triple-negative breast cancer cells by targeting the RAF/MEK/ERK pathway | journal = npj Breast Cancer | volume = 8 | issue = 1 | pages = 40 | date = March 2022 | pmid = 35332167 | doi = 10.1038/s41523-022-00402-4 | pmc = 8948359 }}

Occurrence and isolation
Sulforaphane occurs in broccoli sprouts, which, among cruciferous vegetables, have the highest concentration of glucoraphanin, the precursor to sulforaphane.{{cite journal | vauthors = Houghton CA, Fassett RG, Coombes JS | title = Sulforaphane: translational research from laboratory bench to clinic | journal = Nutrition Reviews | volume = 71 | issue = 11 | pages = 709–726 | date = November 2013 | pmid = 24147970 | doi = 10.1111/nure.12060 | doi-access = free }} It is also found in cabbage, cauliflower, Brussels sprouts, bok choy, kale, collards, mustard greens, and watercress.
Research
Although there has been basic research on how sulforaphane might exert effects in vivo, there is no conclusive clinical evidence that consuming cruciferous vegetables or sulforaphane supplements reduces the risk of cancer or other diseases, as of 2025.{{cite journal | vauthors = van Die MD, Bone KM, Emery J, Williams SG, Pirotta MV, Paller CJ | title = Phytotherapeutic interventions in the management of biochemically recurrent prostate cancer: a systematic review of randomised trials | journal = BJU International | volume = 117 | issue = Suppl 4 | pages = 17–34 | date = April 2016 | pmid = 26898239 | pmc = 8631186 | doi = 10.1111/bju.13361 | doi-access = free|url=https://bjui-journals.onlinelibrary.wiley.com/doi/full/10.1111/bju.13361 }}
