The broccoli-derived compound at the centre of chemoprevention research — and broccoli microgreens carry 10–100× more of its precursor than mature florets.
Glucoraphanin is a glucosinolate concentrated in young Brassica seedlings. When the plant tissue is damaged, the plant enzyme myrosinase converts glucoraphanin into sulforaphane, an isothiocyanate studied for antioxidant, anti-inflammatory, chemopreventive and neuroprotective activity through activation of the Nrf2 cellular-defence pathway.
Broccoli microgreens are among the richest known dietary sources of glucoraphanin, which makes them a strategic feedstock for standardized extract manufacturing.
| Broccoli microgreens | 10–100× glucoraphanin vs mature broccoli — Fahey et al., 1997 (Johns Hopkins) |
|---|---|
| 3–5-day broccoli sprouts | 20–50× glucoraphanin per gram vs mature florets |
| Kale, radish, mustard microgreens | additional glucosinolate profiles |
Studied in oncology, neurodegenerative and cardiovascular research programmes.
Broccoli extracts standardized to glucoraphanin / sulforaphane yield.
Antioxidant and skin-protection actives (Nrf2 pathway).
Young Brassica seedlings front-load defence compounds, so glucoraphanin runs 10–100× higher per gram than in mature florets — far less biomass for the same yield of active.
Yes — cultivar, light recipe and harvest day are controlled to hit a target precursor level, and we can supply to a specification.
Glucoraphanin is the stable precursor stored in the plant; the enzyme myrosinase converts it to the active sulforaphane when tissue is disrupted.
